This case study describes use of the Homework Success Program (HSP) for a child with attention-deficit/hyperactivity disorder (ADHD), predominantly inattentive type. Larry, an 8-year-old boy, presented with homework-related difficulties, including difficulty “focusing” and “sustaining attention,” becoming “easily distracted,” spending 3 to 4 hr per night on homework, forgetting to bring home books, and inconsistently writing down assignments in his planner.Treatment with the HSP included a seven-session intervention with a 1- and 7-month follow-up,which resulted in parent-reported improvements in Larry’s homework performance, homework completion time, and the percentage of homework completed. Parental satisfaction with the program was noted. Results of treatment revealed minimal change in teacher-reported academic performance. Recommendations for successful implementation of the HSP are provided.
