Tutor Quality Is Not Tutor-Student Fit: Evidence from Online Secondary-School Tutoring
Tutoring platforms screen tutors on quality, yet families often say a tutoring relationship failed because the tutor did not suit the student. This study tests whether tutor quality and tutor-student fit are really different things, using administrative records for 220 tutoring relationships on an online IGCSE platform, 178 student questionnaires, 163 parent questionnaires and 134 matched student-parent pairs.
They are. Quality and fit were essentially uncorrelated and loaded on separate factors, and each was independently associated with student satisfaction, with fit carrying the larger weight. About a third of the variation in perceived quality lay between tutors, while fit showed essentially none: the same tutor suited some students and not others. On the parent side, perceived value and platform responsiveness were each linked to satisfaction, while the session fee added nothing once value was accounted for.
The practical conclusion: selecting better tutors and matching them better are different problems. The paper proposes a short pair-level check after the first or second lesson, asking about pace and suitability rather than the tutor's competence, to catch a mismatch before it ends the relationship.
I provided the study setting and administrative records and contributed to the design of the questionnaires. Data were collected in May and June 2026 under formal ethics approval.
