KIPP followed its 8th grade graduates, who were overwhelmingly from poor (85%) and minority (95%) families, and found that, ten years later, 1/3 of them had graduated from college, a rate that was about four times their expected graduation rate and the same as that of white students.
Together, the four schools began with a combined total of 312 fifth graders in 2003-04, and ended with 173 eighth graders in 2006-07 (see Exhibit 2-3). The number of eighth graders includes new students who entered KIPP after fifth grade (p.12) (my bolds).
A major issue in higher education is the disparities in enrollment, persistence, and attainment among low-income students. IPEDS [Integrated Postsecondary Education Data Systems] does not collect income data on students and therefore does not have the ability to provide graduation rates by student income (American Council on Education, 2010, p. 9).
