This book features the most up-to-date versions of assessment instruments to measure individual achievement and learning disabilities. The authors' pragmatic approach offers practitioners an innovative, systematic assessment framework that applies Cattell-Horn-Carroll (CHC) cognitive theory and blends cognitive testing and Response-to-Intervention (RTI) methods into one seamless process for diagnosing learning disabilities. Replete with case studies, checklists, and worksheets, this reference assists practitioners in choosing appropriate tests, organizing comprehensive assessments, and interpreting results using a cross-battery approach. Part One focuses on the evaluation and identification of learning disabilities, particularly from the perspective of IDEA 2004. Current cognitive theory, research, assessment methods, and interpretive techniques are all set forth and reviewed. Part Two is the 'Desk Reference' section. It features descriptions and reviews of the psychometric, theoretical, and qualitative features of more than 50 achievement tests published between 1995 and 2006. Part Three provides a comprehensive, step-by-step explanation of evaluating suspected learning disabilities according to IDEA 2004 guidelines, using the principles and procedures described in the previous two parts. This reference concludes with fifteen appendices providing practitioners with a host of useful information and tools, including reproducible worksheets, conversion tables, and learning disability resources.
