Students who won a lottery to attend a KIPP school in Lynn, Massachusetts learned more in the following three years than those who applied but lost the lottery, concludes a working paper posted on the National Bureau of Economic Research site.
The school predominantly serves Hispanic students, many of whom are still learning English, reports Inside School Research.
MIT, Harvard and University of Michigan researchers found overall learning gains for KIPP lottery winners with the biggest gains for “English-language learners, special education students, and those who started out with low baseline scores.” In other words, the school did the most for the kids with the greatest needs.
The study also challenges the idea that KIPP schools have high attrition rates by offering some evidence that, in this case at least, the lottery winners were actually less likely to change schools.
With a longer school day and year, KIPP students spend a lot more time in school than students at traditional public schools, Debra Viadero notes. That seems to pay off.
