This online research compendium summarizes 143 studies (including 49 reviews of research) referenced in the recent report: Community Schools as an Equitable School Improvement Strategy: A Review of the Evidence. It is intended to serve as a resource for policymakers, practitioners, and researchers who are interested in the community schools evidence base.

The study reviewed research regarding community schools as a comprehensive approach, and research about each of four pillars of community schools, listed below. Accordingly, this document is organized into the following sections:

- Integrated student supports (often called wraparound services)
- Expanded learning time and opportunities
- Family and community engagement
- Collaborative leadership and practice
- Comprehensive community school programs
- Cost-benefit studies

In order to view studies within a particular section, click on the tab at the bottom of the page. Within each section, studies are grouped by original research (at the top of the page) and research syntheses (lower down the page). Within each subsection, studies are organized by Every Student Succeeds Act (ESSA) evidence tier, and then alphabetically within ESSA tiers by study name. According to the law, ESSA evidence tiers are designated as follows:

- Tier 1: Strong Evidence - At least one well-designed and well-implemented experimental study
- Tier 2: Moderate Evidence - At least one well-designed and well-implemented quasi-experimental study
- Tier 3: Promising Evidence - At least one well-designed and well-implemented correlational study with statistical controls for selection bias
- Tier 4: Emerging Evidence - Demonstrates a rationale based on high-quality research findings or positive evaluation that the intervention is likely to improve student outcomes. Includes ongoing evaluation efforts.
