Research Database

This tool allows education practitioners and researchers to quickly access quantitative research on tutoring program effectiveness. These 150+ research studies were selected due to their rigorous research designs which align with What Works Clearinghouse and Every Student Succeeds Act standards for moderate and strong evidence of intervention efficacy. Many studies were originally identified by their inclusion in recent meta-analyses (Baye et al., 2018; Neitzel et al., 2021; Nickow et al., 2020). Research may be sorted by grade level, subject, and tutor type in order to explore the evidence base for particular program designs. This database does not include qualitative research on best practices for tutoring implementation, for which we recommend exploring our District Playbook and Toolkit for Tutoring Programs.
