Which is better: one-to-one or small-group tutoring?
Neither format is always better. The Education Endowment Foundation (EEF) rates both approaches as effective on average: about five months of additional progress for one-to-one tuition and four months for small-group tuition. Those figures summarise school-focused studies; they are not a promise for an individual child, subject or private tutor.
“Studies comparing one to one with small group tuition show mixed results.” — Education Endowment Foundation
One-to-one is usually easier to justify when a child needs a private space to admit confusion, has unusually uneven gaps or needs the tutor to change pace and explanation immediately. A genuinely small, well-matched group can be a strong fit when learners share a goal, stay active and benefit from discussion or shared practice. For this guide, small-group tutoring means one tutor working with two to five learners, following the EEF evidence definition rather than a statutory UK-wide rule.
