In this paper the authors extend recent work on mediation in a multilevel setting and on causal inference under interference among units to develop a template for the mediation analysis of group randomized educational interventions. The present work will contribute to the literature on interference, in particular on interference in the context of…

Summer setback, which is defined as a decline in academic achievement over the summer months, occurs in many academic areas but seems especially problematic in reading.

When attempting to determine if an intervention has a causal impact, the "gold standard" of program evaluation is the randomized controlled trial (RCT). In education studies random assignment is rarely feasible at the student level, making RCTs harder to conduct. School-level assignment is more common but this often requires considerable resources…

After-school programs receive federal support through the 21st Century Community Learning Centers, established in 1999. A primary purpose of the program is to provide opportunities for academic enrichment to help students meet state and local standards in core content areas.
