Study: Harlem charter boosts ‘human capital’

The Harlem Children Zone‘s Promise Academy, a charter middle school, raises test scores, concluded Harvard EdLabs researchers Will Dobbie and Roland Fryer. Sixth-grade lottery winners close the black-white achievement gap by the end of eighth grade.

A new study finds that students are more likely to graduate from high school and enroll in college, less likely to experience teen pregnancy or incarceration.

That’s a huge human-capital boost, notes Education Gadfly.

Six years after winning the admissions lottery, Promise Academy students not only score higher on the nationally normed Woodcock-Johnson math achievement tests than lottery losers, but they are more likely to enroll in college, by 24 percentage points. Additionally, female lottery winners are 12 percentage points less likely to become pregnant in their teens, while males are 4 percentage points less likely to be incarcerated. The Harlem Children’s Zone social and community-building services are well documented, but Dobbie and Fryer attribute Promise Academy’s success to the markers that make it a high-performing school (extended school time, high-quality teachers, data-driven decision making, and heightened expectations).

Winning the charter lottery had little effect on students’ health or likelihood of using drugs and alcohol.
