Comprehensive evaluations are necessary to provide the most effective treatment.  Assessing resources and strengths are viewed as important as evaluating current problems.  Both subjective and objective information are obtained.  Subjective information includes behavioral questionnaires completed by parents and teachers as well as self-rating scales completed by the patient.  Objective information includes the patient's performance on computerized attention and cognitive-skills tests.  Traditional intelligence and achievement testing, administered one-to-one, is also often given. 

An added evaluation feature often used at the Attention and Learning Clinic is a simple quantitative analysis of the patient's EEG.  With ADHD patients who choose to use medication, the most promising medication can usually be recommended by analyzing the person's brain wave patterns.  The method is similar to Daniel Amen's use of SPECT scans to choose the most appropriate medications.
