New York City released its study of the SHSAT. Here’s why it won’t end the admissions debate.

Still, the study doesn’t address key questions about whether the SHSAT is any better at predicting student success than the alternative system de Blasio put forward. And it can’t get at the heart of the debate about the importance of diversifying the elite schools.

The study uses data from every single eighth grade student who took the SHSAT between 2005 and 2009, looking at whether a student’s score seemed to predict early success in high school. It finds a relatively strong relationship between SHSAT scores and early high school performance.
