Working Paper - Recruitment, Training, & Support: Impacts of A District-Partnership Tutoring Model to Support Elementary Literacy Skills

December 2025

This study presents findings from a multi-site student-level stratified randomized evaluation of Ed Corps, a tutoring program that provides tutor recruitment and training as well as implementation support for high-impact tutoring. We find that relative to a business-as-usual control, students in grades K-3 assigned to receive Ed Corps-supported tutoring score 0.15 SD higher on their end-of-year DIBELS Composite scores and 0.18 SD higher on a researcher-developed index aligned to the specific literacy skills each student struggled with at the beginning of the year. While we find positive (though not significant) impacts for a wide variety of student and school subgroups, there is some evidence that boys may benefit more than girls, potentially due to different experiences in Tier 1 instruction.
