I use this form in grades 7-12 to encourage students to correct tests. I give back half of the lost points for each corrected answer, but I require students to explain first how they messed up and how to arrive at the correct answer. I fill out the top portion with the points possible to earn back before I hand assessments back. I also require a parent signature to keep everyone involved. There are two pages that I copy front to back. Suitable for all subject areas.
