Typical Tutor-to-Supervisor Ratios in High-Impact Tutoring Programs

What is the typical ratio of tutors to supervisors in tutoring programs across the country? While a robust body of research exists documenting the optimal ratio of tutors to students in high-impact tutoring programs serving P-12 students, little published information exists on the typical or optimal ratio of tutors to supervisors.

The Partnership for Student Success (PSS), based at the Johns Hopkins University Everyone Graduates Center, set out to learn more about this question during the summer of 2026 by conducting a survey of tutoring providers in its national network of hundreds of nonprofit organizations, school districts, and higher education institutions that work to expand evidence-based and people-powered K-12 student supports.

Through a convenience sample survey of tutoring programs, PSS was able to glean initial insights into tutor-to-supervisor ratios used by a range of tutoring programs. Overall, tutoring programs that responded to the survey reported a wide range of tutor-to-supervisor ratios in their programs, from two tutors to every supervisor, to 80 tutors per supervisor.
