Mathematica's latest report shows that 21st Century after-school programs, which currently spend $1 billion a year in federal funding, changed where and with whom students spent some of their after-school time. But our analysis also reveals that programs had only limited influence on academic...

Describes how various components of Mathematica's complex study fit together and explains perspectives and principles related to 1) distinguishing implemented programs from intended ones, 2) ensuring broad coverage to explore competing theories of effective programming, 3) collecting...

This article presents evidence from the elementary school component of Mathematica’s national evaluation of the 21st Century Community Learning Center afterschool programs. The findings indicate that the programs affected the supervision students received after school, with parents less likely...
