More Reform Funded Research: KIPP Graduates Persist In College At The Same Rate As Their Mothers

Education Reform propaganda at The74 would try to make you believe that while low income students generally graduate from college at a rate of about 9%, charter school graduates complete college at a rate of 3 to 5 times that.

The main flaw in any comparison between the college graduation rates of charter school graduates to low-income students, in general, is that the charter school students do not represent a random sampling of the general population of low-income students.

In The Alumni, Richard Whitmire says that charter schools that have 5 times the expected college completion rate are ones that only counted their students who persisted until 12th grade in their charter schools.  Since for some charter schools, this only represents about 25% of the students who started in that charter school, this even more of a biased sample.  But, Whitmire explains, the one network that has the most valid way of doing a fair comparison is the famed KIPP network.  Since KIPP counts, in their data, any students who enrolled in KIPP, even if they left soon after starting.  And he says that KIPP students, including ones who didn’t persist at KIPP, graduate college 3 times the expected rate.

Reform supporting billionaire John Arnold commissioned Mathematica, a data analysis company, to study the college enrollment and college persistence of KIPP students.  Instead of comparing KIPP students to the general population, they compared KIPP students to students who had applied to the KIPP lottery but did not get into KIPP through the lottery.  This is a much more valid way of measuring the impact of KIPP.  The big takeaway, as I wrote about in my previous post, was that students who applied to KIPP, whether or not they got into KIPP, had a college persistence rate of about 3 times the general low-income population and that students who applied but didn’t get into KIPP had about the same college persistence as students who applied and did get into KIPP.  So students to apply to the KIPP lottery are the ones who, on average, were much more likely to persist in college — something that Whitmire never mentions in The Alumni.

But this Mathematica report includes some other relevant data that I didn’t pick up on when I wrote the last post.  Fortunately there was a discussion among some readers who commented on the last post which pointed this out.

In 2018 the National Center For Education Statistics published a report called ‘First-Generation Students College Access, Persistence, and Postbachelor’s Outcomes.’  In it they say that about 70% of students who have a parent who completed college also complete college compared to about 35% of students who do not have a parent who completed college.  This confirms what most people would expect for so many reasons and this is why we celebrate when students are the first in their family to graduate college.  It means that the descendants of those students will also be more likely to go to college.

In the Mathematica study, they collected statistics about the pool of students who applied to the KIPP lottery.  Among those statistics was the level of education attained by the mother of the KIPP lottery applicant.  Here’s what it says (page 6 of the report):

Notice that last line.  It says that of the students entering the lottery about 27% of them had mothers who finished college.  This makes the fact that about 30% of the students in the study (which includes students who got into KIPP and also students who did not get into KIPP) have persisted in college through four semesters even less surprising.

Someone like Richard Whitmire suggests in his analysis that has been quoted in USA Today and The Wall Street Journal, that had these students not gone to KIPP they would have only persisted in college at around 9%.  But it can be clearly seen now that even without going to KIPP, these students should be expected to have about a 30% college persistence rate.

Data, like what percent of charter school applicants have parents who are college graduates, are so important but nearly impossible to actually learn.  Thanks to the John Arnold Foundation for commissioning this study and shedding light on a truth that we already knew but didn’t yet have hard data to support.

    Don’t forget to (always) mention that John Arnold became a billionaire through Enron, wreaking massive destruction as he amassed riches.

    It’s not news that parent education level is a strong predictor of student achievement and college persistence. We’ve known this at least since the 1966 Coleman Report and other studies have indicated it, too, including in different countries such as the UK (see:, as with family income.

    A few years ago, when KIPP was boasting that one of their schools was outperforming the local public school they were co-located with in California, I looked into it and discovered the parent education levels of KIPP students were considerably higher than the education levels of parents of the students in the public school. I don’t know if that’s typical for KIPP parents, but I think it should be examined closely in every efficacy study of KIPP.
