Assessments for AD/HD typically include 2 to 4 hours of formal testing, as well as parent/teacher questionnaires and interviews. Your doctor may request such an evaluation if the diagnosis of AD/HD is unclear from his/her medical examination.
For learning disabilities, more testing is often required (typically 6 to 8 hours) in order to delineate strengths and weaknesses in the areas of phonemic awareness, orthographic awareness, academic fluency, language, memory, and problem solving. A LD assessment is often requested when a child’s learning abilities are not clear from the results of a school-based assessment or parents seek a comprehensive, outside-of-school evaluation.
Assessment of more complex neuropsychological and neurobehavioral disorders (traumatic brain injury, autism spectrum disorders, medical/genetic disorders) and Independent Education Evaluations for school districts are additional areas of expertise. Evaluations are highly individualized, depending on referral questions.
