Some Philadelphia programs have been evaluated to show positive impacts. Here are some recent evaluations.

Philadelphia Low Intensity Community Supervision Experiment

This program reduced the amount of community supervision of low-risk criminal offenders in Philadelphia. Participants in the program received fewer visits per year from their probation officers than they would normally. The study found no increases in crime from reducing the amount of supervision from probation officers.

The Impacts of Philadelphia’s Accelerated Schools on Academic Progress and Graduation

Philadelphia’s accelerated schools are full-time academic programs for students who are at risk of failing to graduate. In 2010, researchers from Mathematica Policy Research evaluated the effectiveness of Philadelphia’s accelerated schools. This evaluation demonstrates that these schools increase graduation rates among students who are at high risk of dropping out of school.
