Personalized Learning
High dosage tutoring – defined as tutoring embedded during the school schedule that ensures students work consistently on individualized instructional content with their tutor throughout the school year – is among the most effective and cost-effective learning interventions studied to date.
However, schools still face barriers to bringing high dosage tutoring to all students who could benefit. We work in partnership with school districts to understand whether and how we can scale high dosage tutoring programs to reach tens of thousands more students without compromising effectiveness.
The COVID-19 pandemic has exacerbated long-standing disparities in educational performance and attainment along race and class lines. Without dramatic intervention, we risk permanently reversing decades of steady, incremental progress in improving student outcomes. More importantly, we risk shortchanging students–primarily Black and low-income students–the opportunity to learn for decades to come. Despite the scale and gravity of the challenge, we know that there is an effective solution to address learning loss: high dosage tutoring. Research by the Education Lab, in partnership with CPS and Saga Education, shows that when done well, this approach can double or even triple the rate of student learning.
The Education Lab, in partnership with MDRC and Saga Education, is helping districts scale and rigorously study high dosage tutoring supports so that more students might benefit.
Our evaluation of Saga Education found that students who participated in Saga’s high dosage tutoring program for a single year gained 1-2.5 years of additional learning compared to students who did not.
At least 30 minutes of intensive, individualized instruction three or more days per week is one of the most effective learning interventions studied to date.
