Revising and updating the first edition of a best-selling text, this volume is organized around a four-step conceptual framework for the direct assessment of academic skills. Illustrated with numerous case studies, the book contains step-by-step instructions for assessment of the instructional environment, assessment of curriculum placement, instructional modification, and progress monitoring. Revisions to the text reflect important changes in teaching practices since the first edition was published, as well as new intervention strategies; and references, forms, and charts have also been completely updated. A companion workbook offers practice exercises that supplement the book's presentation of assessment and intervention strategies.
