The rapport with the parent is as just as important as the tutee. In order to make a success of the tuition, it's paramount to have a good professional relationship with both. I use feedback from the tutee's parent (via a school report) and informal feedback from the tutee to create an Individual Tuition Plan which includes setting three clear targets. Depending on the key stage and ability of the tutee, this can range anything from parenthetic comma use to translating Chaucerian poetry!
