AFT Pushes Boston Public Schools to Become Part of AI Scourge in the Classroom

 

This could not have happened without a push from BTU—an AFT affiliate. Randi Weingarten, who heads the AFT, has been working overtime to promote her $$$ deal with tech bros to “train” teachers to bring this shit into the classroom: www.schoolsmatter.info/2025/07/aft-...

Get Ready for Boston Schools' CorporatePower Compact

With the Mayflower Compact having been signed just down the road from here way back in 1620, the present-day Lord High Mayor Menino's appointed toadies will meet publicly Monday evening at English High School to formalize a brand new compact that will govern relations between the public schools and the separatists of the corporate welfare charter school sect.  As indicated in an earlier notice, "the draft Compact is similar to agreements announced in December 2010 involving nine cities that were part of an initiative supported by Royalty's Bill & Melinda Gates Foundation."

The outcome of this coming Monday's meeting is a forgone conclusion, so any citizen who may have hoped to influence the final contents to the new compact (read the Boston Globe editorial on the proposed Compact) should not waste your time crafting a public comment.  King William (Gates) already has his tax-sheltered corporate jet scheduled to fly him here on Tuesday for the ceremonial signing by the Elect (not to be confused with the elected).

The CorporatePower Compact is between Boston Public Schools and the Boston Alliance of Charter Schools, even though the latter group does not yet exist as an entity recognized by Massachusett's Secretary of State, or Google.  Those kinds of details cannot stop progress, however.  After all, there is a crisis that requires immediate action without a second more of the time-wasting democratic dilly-dallying. In the words of another separatist of the Mayflower era, John Winthrop,  “A democracy is ... accounted the meanest and worst of all forms of government.”
 
The text of the CorpPower Compact:

Loyal Subjects of our dread Sovereign Lord, King William (Gates), by the Grace of Mammon, of Taiwan, the U.S. and China, the Broad and Walton Foundations, etc. King, Defender of the Faith in Capitalism, e&;. Having undertaken for the Glory of Profit, and Advancement of the Philanthrocapitalist Faith, and the Honour of our King and and Oligarchy, a mission to plant the first publicly funded schools of corporate governance in the Northeast; do by these presents, solemnly and mutually in the Presence of Mammon, King William (Gates) and one of another, covenant and combine ourselves together into a corporatized Body Politick, for our better Ordering and Preservation of the Business Roundtable's Bottom Lines and Illusion of Competition, and Furtherance of the Ends aforesaid; And by Virtue hereof to enact, constitute, and frame, such unjust and unequal Laws, Ordinances, Acts, Constitutions and Offices, from time to time, as shall be thought most meet and convenient for the General good of the Plutocrats; unto which we promise all due submission and obedience. In Witness whereof we have hereunto subscribed our names at Boston the ____ of September, in the Reign of our Sovereign Lord, King William of Redmond, Silicon Valley, Bangalore, etc. Anno Domini, 2011.

Boston's Appointed Superintendent and School Board Couldn't Be More Polite and Undemocratic

Last updated December 17 8:30 AM
The air of irony last evening could not have been thicker at the first public high school of Boston, as all the children in the audience at Boston's Public High got an unforgettable lesson in what democracy does and doesn't look like.

On the "doesn't" side was the feckless School Committee, peering down from the stage of the school auditorium at speaker after speaker, 70 in all, most of whom came to speak against the impending school closures.  The seven appointed Board members and their appointed Superintendent of Schools sat, some leaning forward, some flouncing, some yawning, some chatting, and all waiting patiently for the anticlimactic climax, to make the centrally-planned backroom decision official, while thumbing their noses at the citizenry, regardless of pleas, logic, tears, begging, demonstrations, catcalls, raps, and the rest.

The school closing decision, of course, had been made for them, and they were there last evening to play their bit parts in the democratic farce that has come to the Commonwealth where Horace Mann battled for the creation of public schools, where Benjamin Roberts, Robert Morris, Frederick Douglas, and Charles Sumner made the case for integrated public schools a hundred and sixty years ago.  Now looms the incredible specter of a system based on apartheid, zero-tolerance charter school chain gangs in the black and brown areas of the City.

The children in the audience last night also saw the promise of a democracy renewed in the strong, eloquent voices of their friends, teachers, parents, bus drivers, school helpers, and community activists, who are now galvanized by the decision of the Mayor, the Chamber of Commerce, and the corporate foundations to turn their backs on so many amazing school programs and committed teachers and energized parents.

The School Committee vote last evening was one of the first bombs lobbed into the laps of Boston's public school parents, teachers, and students, and there are sure to be more.  Waiting with their anti-public strategies wrapped in measured, unyielding, Puritan politeness are the charter zealots and the corporate CMOs, EMOs, and CEOs who see education as a controllable commodity whose production cannot be exported but can be exploited for economic gain.

The next bomb will try to blow apart teachers and parents, with school resources or teacher salaries on either side of the crater.  And waiting in the wings for the empty school properties are the charter schools, which in fact are the reason for the $63 million shortfall to begin with.  If Boston were not paying for these charter schools and the incredibly expensive and inefficient transportation to them, there would be no shortfall of $63 million.

The day before yesterday the Mayor was the invited speaker at the Annual Breakfast hosted by Chamber, where he stood before a backdrop of Bank of America and Chamber of Commerce logos to announce the closings or mergings that got formalized last evening.  And even though the mayor got his first standing ovation in all his speeches to the Chamber of Commerce, he should enjoy it while he can.  The Boston public is aroused and angry and ready to act.  If you thought you saw repudiation in Washington, DC in November, just wait.  This could easily be the event that signaled the beginning of the restoration of public control of the Boston Public Schools.  

Finally, one of two elected official to speak last evening was City Councilman, Felix Arroyo, whose eloquent appeal to save the schools fell on the same deaf ears.  When the Councilman's 2 minutes were almost up, he was reminded by the Committee's timekeeper on the stage.  Someone in the audience yelled, LET HIM SPEAK--HE WAS ELECTED!

Perhaps in the not so distant future, those on the stage will be elected as well.  Let's make it happen.  Let's restore Democracy to the Cradle of Democracy in America.

Boston Cutting Property Deals with Charters as Charters Recruit Top Scorers and Private School Students

What is that smell wafting up over the Charles River this morning?  Oh, it's the stench of corruption as a whole bunch of public schools are shuttered, kids are dispersed, communities blown up, and fat cats in in the corporate foundations get ready to carve up the empty school properties for their corporate welfare charter schools.  
After I reported that Roger Clap Elementary School would be spared from closure, the Boston Public Schools “Redesign” site appeared to be updated with a list of proposed closures and mergers. And now, about 10 minutes later, the list is gone.
We were able to grab the list before it disappeared. Here it is:
  • Merge Lee Academy with Lee Elementary, create a K-8
    Lee Academy would become a K0-1 program and Lee Elementary would operate a Grade 2-8 program. Both would exist in the same building as they do today.
  • Merge Alighieri and Umana
    These schools would merge to create a K-8 in the Umana building. The Umana is also scheduled for a major renovation within the next two years, so the K-8 would be phased in.
  • Merge Urban Science Academy and Parkway Academy of Technology and Health
    These schools would merge to create one school, led by USA. The programs would stay in the same building.
  • Merge Brook Farm Business & Service Career Academy and Media Communications Technology High School
    These schools would merge to create one school. The programs would stay in the same buildings.
  • Merge Excel High School and Monument High School
    These schools would merge to create one school, led by Excel. The programs would stay in the same buildings.
  • Expand Holland Elementary
    Add one K1 classroom.
  • Expand Trotter Elementary
    Add one K1 classroom.
  • Expand King K-8
    Current East Zone ELC K1 and K2 students move to the King.
  • Relocate Community Academy of Science and Health
    Relocate program to the Cleveland Building in Dorchester (East Zone).
  • Unite and expand TechBoston Academy
    TechBoston Academy will become a unified Grade 6-12 program at Dorchester Education Complex, and increases high school seats.
  • Move Dorchester Academy
    Program moves from Dorchester Education Complex to the Wilson Building.
  • Close East Zone ELC
    Current K1 and K2 students are relocated to King K-8 if they choose
  • Close Fifield Elementary
    Students have priority for available East Zone schools, after sibling preference is taken into account.
  • Close Middle School Academy
    Program moves to the current Gavin building
  • Close Emerson Elementary
    Regular education students have priority for available seats in the North Zone, after sibling preference. Cape Verdean SEI students move together to a different school.
  • Close Farragut Elementary
    Students have priority for available seats in other North Zone schools, after sibling preference.
  • Close Agassiz Elementary
    Students have priority for available seats in other West Zone schools, after sibling preference.
  • Close The Engineering School
    Students have priority for available seats in other high schools, after sibling preference.
  • Close Social Justice Academy
    Students have priority for available seats in other high schools, after sibling preference.
  • Clap Elementary becomes our first “Innovation School”
    Students remain in the school but the program gets a “fresh start.” Apply for Innovation School status granted under new state law.
  • Convert Gavin Middle School to “Up Academy”
    Current Gavin students are guaranteed enrollment in UP Academy as long as they fill out a simple application form. Incoming 6th grade students can apply from anywhere in the city.
A BPS spokesman confirmed the list was published prematurely and the information is correct.
Update: Afer BPS made the list officially official tonight, I see a new item:
  • Expand Dearborn to a 6-12 STEM program
    Dearborn Middle School will become a 6-12 STEM program, focusing on Science, Technology, Engineering, and Mathematics.
And while the BPS tries to figure out how to close the 63 million dollar hole in its budget largely created by the $55 million it will pay out to charter schools, the corporate charters are already sending recruiting letters to high-flying students from the closing public schools, while getting ready to put out the welcome mat for private schoolers, too.  Special ed and ELL students?  Need not apply.

The Globe has a story this morning about backroom deals to carve up the real estate before the announced closing even reached the parents and kids affected:
The Boston Teachers Union is accusing city and school leaders of “meeting secretly’’ last week to offer charter school officials the chance to lease city schools slated for closure, even before parents and students at those schools knew their fate.
In fliers that its 7,000 members will receive today, the union said charter school leaders “are salivating at the possibility of leasing ‘surplus’ Boston School buildings.’’
Richard Stutman, president of the Boston Teachers Union, said he was taken aback by the meeting.
“I don’t get shocked by much, but I was shocked that they met with these folks prior to a School Committee vote and having meetings with the schools,’’ Stutman said yesterday. “This is an economic decision, and this is a decision based on, I think, trying to give charter schools what they’ve desperately needed, which is space.’’
School Superintendent Carol R. Johnson recommended Thursday that more than a dozen schools close or merge as a way to plug a potential $63 million budget gap in a time of declining enrollment and charter school growth. The system has about 5,600 empty seats throughout the city and the suggested capacity reductions would shrink that number by about one-quarter.
The day before Johnson made her recommendations, her staff met with city and charter school leaders to start strategically planning for the growth of charter schools in Boston, instead of just ignoring them, school officials said. The group discussed about two dozen issues, including transportation and students learning English. Capacity was only a sliver of the discussion, school officials said. . . .
You expect this kind of corrupt privatization in areas where disaster capitalism has used economic or natural emergencies to rush in with its shock and awe solutions, but here in the shadows of MIT and Harvard?  How unseemly, indeed.  Tsk tsk.

Boston's Charterizers on the Prowl, Pushing for Closure of Public Schools

Boston's corporate education deform movement has been a study in contrasts to the fuming, snarling Michelle Rhee of DC fame and others of the public education bombardier wing.  The bombers of Boston act with the restraint of Harvard dons in contrast to Rhee and, let's say, the super-sized governor of New Jersey.  Maybe it's because there are, indeed, Harvard dons among them, like master chef of voucher research, Paul Peterson, who is apparently training a new generation of ideologues like himself who can abuse the reputation of a great university to push for the demolition of all things public.  Of course, Peterson is not the only academic turned corporate pawn among the edupreneurs and corporate welfare ditto heads who take orders from the big time oligarchs running the Billionaire Boys' Club.

For Boston's"creative destruction" disruptors, the game is subterfuge, influence peddling, and stealth bombing of the public schools and the teaching profession, when compared to open warfare that has been waged in Chicago and Detroit and New York.  So it must come as a rude and embarrassing shock to see hundreds of parents and teachers and students openly and loudly trying to save their public schools, none of which are on the state's Worst list, from being turned into segregated charter properties to benefit the Eli Broads of the Commonwealth.

From WBUR:
BOSTON — Hundreds of parents and teachers turned out Tuesday night to protest a Boston Public Schools plan to close or merge eight schools.

The district says the cuts are necessary because of an expected $50 million shortfall next year. There are also as many as 5,000 unfilled school seats because so many kids have transferred to charter schools.

WBUR’s Monica Brady-Myerov joined Morning Edition Wednesday to break down the meeting.

Bob Oakes: What was the mood like at the meeting?
Monica Brady-Myerov: It was loud and angry. Before the meeting started, a crowd was chanting, “Save our schools.” This chanting went on for about 20 minutes. Several hundred parents — some with their children — and teachers came with signs and T-shirts. When the meeting started, they charged the stage as school committee members started to take their seats. Boston school police had to get in front of the stage to keep them away.
This shows how hard it is for any district to close a school because every single one of the schools had a representative there Tuesday night, and they’re fighting this.

What has the school committee told these parents about why their schools need to close or merge?
Tuesday night was a hearing, so the committee members didn’t speak, but in previous communications they’ve told parents their top priority is giving students access to stronger programs. And the schools they want to close just aren’t good enough. So the district is citing MCAS scores or the high-school dropout rate to explain why each school should close, but I should note that none of the schools selected by the district are on the state’s “under-performing” list; they’re not in turnaround status. So there are many schools that are doing much worse in the district and they’ll stay open.

What did the teachers, parents and students tell the school committee?
They each had very personal stories, but the message was the same — these schools are being misrepresented by the district as under-performing as an excuse to be shut down. Kenny Jervis, a parent at Roger Clap Elementary School, says he was taken by surprise when he learned his child’s school would close:
Never before have us as parents, our administrators or those children been told they were an under-performing school. We find we had a bad year. Many people, many things, many teams have bad years. The answer is not closing.
Parents also said they learned about these closures through a notice sent home in their kids’ backpacks in early October, and the note said there’d be a meeting that night. They say it’s just all happening too quickly and it’s not fair.

So, what are they asking for now? And are the committee and officials listening?
The parents want the process to start over. The school committee is scheduled to vote on this plan next week and they say the schools would close by the end of this year. And Tuesday night they didn’t say anything about it, so they say they’re listening, but they’re voting in a week. So it’s unclear how much they heard is going to affect their vote.
Richard Stutman, president of the Boston Teachers Union, spoke for teachers:
To close these schools primarily because they are small, or because they want to reuse their buildings or give them to a charter school, is a disservice to all of us who care about good schools, and it will only drive more people away from our schools, especially those schools that work.
Superintendent Carol Johnson shows she is listening to some people because she changed one of the plans Tuesday night: She said the district would not close the Community Academy of Science and Health (CASH School) in the Hyde Park complex. They didn’t give a reason why, but the school officials believe it’s because they refuted the district’s numbers and showed that they do have high MCAS scores. So they’ve shown a willingness to change their minds, but the vote is next week.

So there’s no indication at this moment that they’re not going to ram this thing through?
That’s right.

The Boston Charter School Miracle Turns Mirage

A new study of Boston charter schools shows them to be more mirage than the miracle that the Boston Globe and the Boston Foundation would have the public believe. The clip at left from page 17 (click it to enlarge) shows exactly how the Commonwealth Charter Schools have recently been shown to edge out the Boston Public Schools in MCAS scores.

By having almost no students who are Limited English Proficient (LEP), significantly lower numbers of special education students (with milder disabilities, by the way), and fewer poor students (FRLP), there is no wonder that the charterizers have been able to claim the test score edge.

Subsequent posts will highlight other differences that make a difference in test score performance. The entire study can be downloaded here. And here is Web summary from the MTA site:

The state’s largest teachers union released a report today documenting very high attrition rates and low enrollment of high-need students in Commonwealth charter schools in Boston. The report warns that expanding the number of charter schools without addressing these enrollment practices threatens to separate students based on language proficiency, special education status and poverty.

The report documents that enrollment in Boston’s charter high schools falls precipitously over the years. Fewer than half of the students enrolled in charter high schools as freshmen are still enrolled as seniors. This attrition pattern can be captured by snapshot of any single year. In 2008, for example, there were only two seniors for every five freshmen in the charter schools, while there were four seniors for every five freshmen in the Boston Public Schools.

"Far too many charter schools have established enrollment and exclusion practices that have winnowed out students with greater needs," said Kathleen Skinner, director of the Massachusetts Teachers Association’s Center for Education Policy and Practice. Skinner authored the report, Charter School Success or Selective Out-Migration of Low-Achievers? "By law, public schools are supposed to serve all students in the Commonwealth. In practice, charter schools do not fulfill that mission. We need to face this reality as the Legislature and the public begin debating whether to increase the number of charter schools in this state."

The report focuses on Boston’s charter schools because they have been the subject of recent studies that claimed to find they were doing a better job educating students than the Boston Public Schools. Recent national studies, by contrast, continue to find that most charter schools perform the same or worse than comparable district schools.

"This report shines a light on the shocking loss of students in most Boston charter schools between the year of initial enrollment and the final year," said MTA President Anne Wass. "Students who are not meeting a school’s academic and behavior standards are being sent back to district schools or to the streets, and then exaggerated claims of success are being made based on the small number of students who remain.

"U.S. Secretary of Education Arne Duncan recently described as ‘dropout factories’ schools where two out of five of their freshmen are not enrolled at the start of their senior year," Wass continued. "By that standard, Boston’s charter high schools are among the worst ‘dropout factories’ in the state."

One way to look at the high school attrition rate is to compare the number of students enrolled in grades 9 and 12 in a given year. In Boston’s five charter high schools in 2008, there were only two seniors enrolled for every five freshmen -- a reduction of 57 percent. By contrast, the senior class in BPS high schools that year was four-fifths the size of the freshman class -- a reduction of just 19 percent.

Looking at it another way, how many students leave Boston’s charter high and middle-high schools from the year they enroll (generally grade 9, but earlier in some schools) until the start of their senior year? Again, the loss is dramatic.

For example, the MATCH school is often cited as a success story since the school claims that 99 percent of its graduates are accepted at four-year colleges. However, that is 99 percent of a greatly diminished pool of students. For the class of 2009, 72 students were enrolled in grade nine but only 34 were enrolled by grade 12, a loss of more than half of MATCH’s students.

The report also provides new details on the major differences in student characteristics. It has been reported previously that charter schools enroll fewer special needs, English language learner and low-income students than their sending districts. This report breaks down the data further, showing that the special needs students enrolled in charters have far fewer disabilities and that their low-income students are less poor.

ELL: ELL students comprise one in five BPS students -- 19 percent -- but only one in 50 (2 percent) in Boston charter schools.

SPED: Twenty percent of BPS students have special learning needs compared to 15 percent in the charters. More significant, however, is that the charter school students on Individual Education Plans have milder special needs.

Special needs students are classified by levels: full inclusion (mostly educated in the general education classroom), partial inclusion (in the middle), and substantially separate (mainly or exclusively taught outside the general education classroom). Students with the most severe needs are placed out of district.

Nine out of 10 (91 percent) of the special needs students in Boston’s charter schools are full inclusion compared to only one-third (33 percent) of BPS students. Nearly half (48 percent) of BPS SPED students are either taught in substantially separate classrooms or placed out of district, compared to only 3 percent in the charter schools.

Type of School% Full Inclusion% Partial Inclusion% Substantially Separate% Out of District
BOS3319417
Boston Charters91630

FRPL: Charter schools claim they serve nearly the same number of low-income students as the BPS system: 71 percent versus 74 percent. But a closer look reveals that they serve fewer very low-income students.

The family income limits to qualify for a free lunch are significantly lower than those for a reduced-price lunch. Two-thirds (65 percent) of BPS students qualify for a free lunch while only half (52 percent) of Boston’s charter school students do.

Type of School% Reduced Lunch% Free lunch
BPS965
Boston Charters1852

Wass said that charter schools were first established to be laboratories of experimentation. "Over time," she said, "they have changed into something else -- essentially a state-managed system of publicly funded private schools." She noted that many are opened by the state over the objections of the local residents and taxpayers who must fund them.

"If we are to have charter schools paid for with public dollars, they should serve all students," said Wass. "They should be accountable to their communities. And they should be funded in a way that does not hurt the quality of education provided to students who remain in the district schools."

Boston Globe Escalates Shilling for Charter Movement

The Boston Globe was panting to get to press last week as the ink was still drying on a new non-refereed charter school study paid for by the Boston Foundation, the prime mover and financial backer of the charter school movement in Massachusetts. The Boston Foundation has a long history of supporting good causes, but it is not good that they are now selling their institutional reputation to Business Roundtable ideologues to advance an agenda for the de-professionalization of teaching, the corporatizing of schools, the elimination of unions, and the intellectual sterilization of urban school children, all to be accomplished while collecting dollar-for-dollar tax credits and pats on the back by those who are clueless on the self-serving nature of this new social entrepreneurial movement—where even acts of giving must be self-serving.

So then the Boston Globe has become the carrier of the corporate message of the “bold reformers,” or the reckless corporatizers, depending on your views of the relative importance of renewing the public commitment to public education—as opposed to embracing private entrepreneurial investments at taxpayer expense, all disguised as public giving and philanthropic goodness.

The Globe first ran a big news piece with graphs and stats last Monday ("Charter Schools Grade Highest), followed up with editorials and op-eds heavy with quotes from insiders at the Boston Foundation. In none of these pieces will you find any of the caveats and limitations that the authors of the study carefully detailed to keep respectable news sources and other readers from doing what the Globe has done. I don’t blame Boston Foundation President, Paul Grogan, from pumping his study. And pump he did in, of course, the Boston Globe:
Paul Grogan, president of the Boston Foundation, which funded the research, was more direct. "There is no justification for keeping a charter cap in place that is denying urban, mostly black and brown children the opportunity for a demonstrably better result," Grogan said.
After all, Grogan's non-profit Boston Foundation (with almost a billion dollars in non-profit) paid for the study and has a huge vested, shall we say, interest in removing the cap on charter schools, thus removing the top on the tax credit cookie jar for all those hungry edu-entrepreneurs seeking to do good. But it is unconscionable that the Boston Globe offer such a one-sided presentation of a schooling situation that is anything but one-sided.

So, then, a few observations on the limitations of the study, since it is obvious that the Globe and the folks at the Boston Foundation are trying their best to paint a picture that only exists in the sunny side of the heads of the “bold reformers.” I will leave the statistical surgery for someone more competent, and I will use largely quotes from the authors, themselves.

The study, Informing the Debate: Comparing Boston’s Charter, Pilot, and Traditional Schools is really two separate research designs under the same cover. It can be downloaded at the Boston Foundation website.

The first part of the study is an observational study, and it examines MCAS test score differences among charters, pilot schools (a sort of hybrid with some charter and some traditional characteristics) and Boston Public Schools (BPS). As indicated by the researchers, themselves, the findings of the observational design are easy to fault because of the selection bias background characteristics that are unaccounted for in the study. Besides attracting parents, for instance, who are more eager to seek out opportunities for better academic results for their children, we know that the charter schools in this study have fewer special education students, fewer English language learners, and fewer poor students. No wonder, then, that these charters outperform the BPS schools and the Pilots.
Charter Schools also serve a smaller proportion of special education students, free- and reduced-price lunch students, and English learners than do the traditional BPS schools. In addition, high school Charter students tend to come in with substantially better math and ELA performance on the MCAS than those in traditional BPS schools (.412 standard deviations higher in math and .412 standard deviations higher in ELA) (p.15).
The authors of the study further concede that
students who go to Pilot and Charter Schools are different in important ways from those that do not. We need to take account of these differences before judging the relative effectiveness of these different school models” (p. 18).
In an earlier section the authors entitled “Caveats,” they go further:
Each design is described in detail on page 8. This study is limited by the constraints of our two research designs. The observational study includes all schools but does not control for unobserved differences in background characteristics. The lottery study controls for all differences in students’ background, including unobserved differences, but does not include all schools.

A second caveat relates to the observed control variables used in our study. These include indicators for participation in special education and limited English proficiency. These broad categories may disguise large differences in student groups. Special education students range from those needing intensive all day services to students needing a little extra time in a resource room. English learners may know no English at all or have some proficiency. It is possible that Pilot and Charter Schools serve different proportions of these subgroups. Unfortunately, our state data set does not provide finely detailed breakdowns for these two variables in a manner consistent or comprehensive enough to be useful for this study (p. 6).
The second research design is what the authors call a lottery study. Students who applied for and were selected into pilot and charter schools were compared to students who applied and were not selected to attend. Their individual test scores were tracked over time to compare the effect of charter schools, pilot schools, and BPS schools. Quite ingenious in design, but extremely limited in the sampling—as noted in the Caveats above. What results is a skewed picture based on a handful of the most popular charters compared with pilots with a much more limited lottery selection compared to the BPS who accept any student who walks in the door (remember public schools?).

. . . it's important to keep in mind that while the lottery study uses a stronger research design than the observational study, both the Charter and Pilot lottery results come only from schools and years in which the demand for seats exceeds the number of seats. Our Charter lottery results also omit schools and years for which lottery records are missing or incomplete. These considerations have the largest impact on the sample of Charter middle schools in the lottery study, where the estimated test score effects are largest.

On balance, our lottery-based findings provide strong evidence that the charter model has generated substantial test score gains in high-demand Charter Schools with complete records. On the other hand, these results should not be interpreted as showing that Boston Charters always produce test score gains. In Charter Schools with lower demand and incomplete lottery records, we have to rely on non-experimental results (p. 39).
And the non-experimental results, remember, are the ones from the observational study that the authors told us that we have to take with a big grain of salt. What does this mean? It means that this study, the one that the “bold reformers” are crowing about did not include test data for students from the lower tier of charter chain gangs, where, of course, the scores are most likely to be equally bad or worse than they are in the poorest public schools that the edu-preneurs don't give a damn about. If they did, they would be putting their money where their mealy mouths are.

And what about this lottery business—didn’t this “scientifically-based” study show the charter schools superior in test results than the pilot schools? Well, just like charter schools, not all lotteries are equal. The lotteries for the pilot schools were conducted after all the guaranteed seats were filled, which means that most of the students attending the pilot schools are there not because of a lottery draw but because they live within a guaranteed proximity of the school. Here comes the self-selection bias again, yes, because ALL of the charter school students are there because their parents cared enough to fill out the app to get them into the lottery. Apples to oranges!

And how many charter school kids are we talking about in this earth-shaking study? Well, in the middle schools, where the significant math gains earned a big chart placement in the Boston Globe, the total number of students was 953 students from four (4) charter schools. A pretty meager sample to use in order to build an argument that charters have kicked butt over the pilots and BPS.

But remember, it doesn’t take much when the media hammer the intended distortion until it becomes an all-pervasive meme that is passed from newspaper to TV and back again. After all, it was just one study, and one that could not even cover its own statistical contortions, by another Harvard rock star, Paul Peterson, that launched the urban voucher movement.
