High-dosage tutoring (HDT) is one of the most effective interventions to boost student learning, but cost and staffing remain barriers to scaling. We ran an RCT with ~4,000 students in two large districts (2018–19, 2019–20), testing a hybrid tutoring model where half of student time was spent with a tutor and half on computer-assisted learning (CAL). This reduced costs by ~30% relative to 2-to-1 tutoring, while producing math test score gains nearly as large as those in prior HDT models. The findings suggest technology can help expand HDT while preserving effectiveness.
