This authoritative guide gives parents the inside scoop on how psychological testing works and how to use testing to get the best help for their child. Two Harvard experts spell out the entire process of testing for dyslexia, ADHD, math and reading disorders, Asperger syndrome, depression, anxiety, and other common childhood problems. Parents learn what different tests actually measure and how to "crack the code" of jargon-filled reports, numerical scores, and educational recommendations. Also discussed are key qualifications to look for in evaluators, what kinds of testing schools are required to provide, and when to consider paying for private testing instead. Comprehensive and accessible, the book includes tips on making testing less stressful for children and loads of resources, FAQs, and examples.
