The most recent of these, from researchers at Stanford University’s SCALE Initiative, examined math and reading tutoring programs in a large, urban district during the 2022-23 and 2023-24 school years. Neither led to overall gains in academic achievement.
But when researchers dug deeper into the data, they identified implementation problems that could be driving these null effects.
The findings add to a growing body of evidence around tutoring in a post-COVID landscape that suggests the effectiveness of a program hinges on the nitty-gritty details of how it is run—how often students meet with their tutors, for instance, or whether lessons are tailored to their specific needs.
Studying these implementation details could help school systems build more effective tutoring initiatives in the long run, said Elizabeth Huffaker, an assistant professor of educational leadership and policy at the University of Florida, and the lead author on the SCALE paper.
