In my ten years of teaching, I have been tutoring for 8 of them and have found that the financial benefits are worth my extra time at school - as long as they're planned well and executed properly. I've put together a packet of forms that I have created to make sure that my year goes well with each individual I tutor.
Students need that one on one time, to continue their success and get the extra boost they need in the classroom. You've already spent time planning for 30+ other students that are your responsibility on your evaluation. Use your resources - the work you have already put in to your own students, will most likely still apply to the individual(s) that you're working with.
Included in this packet are planning forms, data forms, space for notes on each session, and a handful of assessment documentation that you would be able to hand back to any parent/teacher showing the progress you're making during your time together. All are in a word document that you can easily edit to your liking!
