Intelligence Assessments: This type of testing is often required as part of eligibility determination for advanced (gifted)  academic programs and can typically be administered in a single test session from about 9:00 a.m. to noon. If you let me know your ultimate objectives, I will make sure that the tests I administer meet county or program requirements for eligibility determination. The general ability factor of intelligence, usually estimated with an overall IQ score, is the best available predictor of a person’s likely academic and vocational success, so intelligence assessments can be very informative in educational decision-making.
Psychological and Psychoeducational Assessments: Psychoeducational testing is oriented toward identifying areas of academic difficulty (e.g., reading, written language, or mathematics) and the specific cognitive processes that may explain performance problems. Intelligence tests are also typically given. Psychoeducational assessments typically require two half-day (9:00 a.m. to 2:00 p.m.) test sessions. Other measures are typically given for specific presenting concerns, including possible ADHD, anxiety or mood difficulties, or oppositional defiant behavior.  
Neuropsychological Assessments: Usually following an acquired or development brain injury, this type of assessment is the most comprehensive, as it measures performance across multiple mental functions and processes. It includes all of the content measured in psychoeducational assessments, but it extends coverage beyond intellectual and educational performance alone. A comprehensive neuropsychological assessment in my practice typically requires two to four half-day test sessions. I administer a flexible battery, usually a highly modified Halstead-Reitan battery with many process measures. The typical battery measures intelligence, academic skills, attention and  executive functions, memory and new learning ability, and social and emotional adjustment / personality. Other domains that may be assessed, depending on need, include language and communication, visual-spatial processing, and sensory-motor abilities.  
ASSESSMENTS

An Individualized Approach

My approach to psychological assessment is highly individualized. First we talk about the purpose of the assessment and identify the questions you would like the assessment to answer. Next we complete a history--sometimes brief and over the telephone, and sometimes requiring a meeting and interview of one to two hours. Then I select the best-fitting tests for the needs (and unique style) of your child. For gifted eligibility decisions, I will select the measure that is most likely to highlight your child’s strengths. For more comprehensive assessments, I may measure intelligence, academic skills, learning and memory, attention and executive functions, auditory processing, visual-spatial processing, and/or social and emotional adjustment, as well as any other mental functions in question. I administer and score all tests myself, with no student examiners. My comprehensive assessment reports are light years beyond anything available through the public school system, often representing the most in-depth study that will ever be completed of how your child’s mind works. Most children find the tests interesting and enjoyable, and they leave with a toy of their choice from our treasure chest!
