UPDATE:
Within the first week, my son showed a marked improvement in disposition. After 2 weeks, his focus improved slightly. I enlisted the help of a counselor, who suggested behavior inventories based on these attributes: Attention, Compliance, Completion and Quality. Each teacher rates his performance and returns the form to me each week. Also suggested was filming his homework sessions so that he can see and understand how he floats off task. He is back on a low dose of medication which has helped even more with his focus. I see a light at the end of the tunnel, and through therapy, love and behavior awareness, I know that my son will be able to learn and use the tools he needs to succeed academically.
