ADHD is a disorder of attention that manifests itself across settings, home, academic and social. To determine if a student has this condition we conduct a multi-pronged assessment. First. We conduct a psychoeducational evaluation which determines if the student has good basic cognitive and academic skills. We look at language, non-verbal processing, working memory, processing speed, language arts and mathematics. Next we collect information from home and school to determine base activity and attention levels and to see if there are any differences in the two arenas. Finally, students complete a computer based visual and auditory measure which assesses attention and response time. A diagnosis if ADHD is based upon the results of all three of these areas.
