This indispensable book helps school practitioners go beyond putting a label on student behavior problems--it shows how to use assessment to partner with teachers and students to develop effective solutions. The authors provide a framework for determining the types of behavioral data that are needed in a given situation, selecting appropriate measures, and interpreting and organizing the results. Case examples tie it all together, demonstrating how different assessment strategies can be used to support positive behavior and monitor progress at the level of the individual, the classroom, or the entire school. In a large-size format with convenient lay-flat binding, the volume features 15 reproducible checklists and forms. This book is in The Guilford Practical Intervention in the Schools Series.
