Intended for teachers of the learning disabled (LD), the guide addresses philosophical and procedural issues in assessment. The first section introduces a philosophical framework which views assessment as an ongoing, goal-directed, integral part of the overall educational process. The remainder of the guide focuses on Wisconsin's procedures for assessment and touches upon the following aspects: the state's criteria for LD; the multidisciplinary team's role; LD assessment report guidelines; classroom teacher reports; classroom observation cues and guides; interview ideas for students, parents and teachers; diagnosis through teaching; curriculum-based assessment; and instrumentation and technical adequacy of commonly used tests. A list of selected professional readings is followed by a glossary of approximately 70 terms. (CL)
