Allison,
Sounds like a good system! I do something similar by having the student complete a "fill in the blanks" statement regarding what they believe has interfered with their focus, what they could do differently, and moving forward, what they plan to do as a personal commitment to themselves to acheive the skills, knowledge and understanding needed. Although it's not binding, it forces a degree of accountability and in the end contributes to overall better student performance.
