This indispensable volume presents an up-to-date conceptual model and practical tools for meeting the challenges of severe problem behavior in elementary and middle-school settings. The focus is on developing and implementing team-based support plans for the 1-5% of students who require intensive, individualized behavioral assessment and intervention. Outlined are field-tested procedures that enable the practitioner to evaluate student needs using functional behavioral assessment; transform assessment results into practical, function-based interventions; develop school-wide systems that support the assessment and intervention process; establish clear roles for leaders and members of behavior support teams; and work collaboratively with administrators, teachers, students, and parents. A much-needed resource and text, the book features illustrative case examples, figures, and charts. Also included are reproducible assessment instruments, parent and teacher forms, sample meeting agendas, and other useful materials. Note: A less intensive, prevention-oriented intervention for students with moderate problem behavior is presented in the complementary volume, Responding to Problem Behavior in Schools.
