The fourth edition of this popular text is again written specifically for the majority of future teachers—those who will teach in public school special education classrooms. This text offers everything these teachers will need in order to assess pupils with mild to moderate disabilities—and presents these complex concepts in a straightforward, step-by-step manner complete with practice exercises for every step, case studies, and plenty of measurement examples. From calculating chronological age scores and raw test results, to effectively writing educational objectives required for IEPs, every pertinent issue is thoroughly addressed, including the most recent federal mandates of the 1997 IDEA Amendments.
