The purpose of this case study was to determine specific academic and social deficits in executive functioning exhibited by students diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). The subject in the study was an eighteen-year-old male. Baseline data were gathered from researcher observations and teacher surveys. Self-evaluation surveys were implemented to determine how the subject perceived deficits in executive functioning in relation to his academic performance. This study shows that further research is needed in specific areas of executive functioning.
