Specific tuition programs often involve comprehensive training for the educators involved. In these cases, tuition delivered by para-professionals can be as effective as tuition delivered by teachers. Para-professionals can come from a range of backgrounds, but they tend to be well-educated, well-trained, and compensated for their time. The majority of studies use pre-service teachers, university graduates, or teaching assistants. As would be expected, qualified teachers are very effective tutors, whereas non-professional tutors without training tend to be ineffective.
Previous research highlights the importance of regular communication between educators delivering small-group tuition and classroom teachers. This might involve establishing a plan for ongoing collaboration and updates about student progress.
