This technical report examines whether high-dosage tutoring can be scaled across diverse districts in ways that meaningfully accelerate learning. Drawing on decades of evidence, the report reinforces that tutoring is most effective when it is frequent, individualized, delivered during the school day, and aligned with core instruction—not treated as informal homework help.
Across 2022–23 implementation efforts in districts including Chicago Public Schools and Fulton County Schools, results suggest that in-school tutoring can generate large gains in math achievement (about two-thirds of a year of learning), while reading results are still emerging.
