The study, which was posted online in late August 2024, tracked almost 7,000 students who were tutored in Nashville, Tennessee, and calculated how much of their academic progress could be attributed to the sessions of tutoring they received at school between 2021 and 2023. Kraft and his research team found that tutoring produced only a small boost to reading test scores, on average, and no improvement in math. Tutoring failed to lift course grades in either subject.
