New Data on KIPP presented in the Big Easy (April 8, 2011)
Posted by GRitter | Arkansas, Education, Politics | April 14, 2011
It’s too bad that the obviously-flawed Western Michigan study targeting KIPP received so much media attention. Author Gary Miron (Fellow at NEPC) was covered in Education Week, the New York Times, and numerous other lower-profile outlets throughout cyberspace. It was even covered here in our Democrat Gazette on April 1 (“Study assails charter school network’s feats; KIPP calls data flawed”). KIPP provided its official response here very quickly after the Miron report came out.
So, who should we believe? Where should we turn for the truth? KIPP – of course, it seems clear that KIPP has an interest in presenting a positive picture. As for Miron – it is at least the case that Miron’s past work has been critical of charters with potentially shaky methodology and that he belongs to groups that are typically antagonistic to charters and choice-based reform (Fellow at NEPC). Given all of that, let’s skip past the criticisms of Miron and the responses of KIPP and look for answers elsewhere, by somebody with no dog in this hunt.
Fortunately, just this past week, I was at AERA (American Educational Research Association) in New Orleans and attended two presentations at which researchers from Mathematica Policy Research , or MPR, (a well respected third party research firm) presented results from its multi-year evaluation of KIPP schools across the country. Here are the key findings, taken verbatim from report:
***
In the first report from that evaluation, “Student Characteristics and Achievement in 22 KIPP Middle Schools” (Tuttle et al. 2010a), we presented preliminary findings from a matched, longitudinal analysis designed to estimate KIPP’s effect on student achievement in a nationwide sample, the first study of its kind. Students entering these 22 KIPP middle schools typically had prior achievement levels that were lower than the average for the local school districts. Still, for most of the KIPP schools studied, quasi-experimental impacts on students’ state assessment scores in mathematics (18 of 22) and reading (15 of 22) were positive, statistically significant, and educationally substantial.

AND, regarding alleged high rates of attrition:
***
Second, the report examined rates of attrition from KIPP schools relative to attrition from nearby traditional public schools. The data in that report showed that students do not leave KIPP middle schools before completion (finishing eighth grade) at higher rates than do students in local district schools. The cumulative attrition rate (defined below) in KIPP was 34 percent, compared to 33 or 35 percent, depending on how one defines the comparison group of “local district schools.”
***
Mathematica will report next year on a random assignment study of KIPP schools to further investigate the academic impacts of KIPP. But as of now, it looks like KIPP is doing well by its students. And these good results are not due to smoke, mirrors, or attrition; it looks like these results stem from strong leadership, great teaching, and hard work!
Congratulations KIPPsters!
