Problem-­solving assessment is an essential component of multi-­tiered systems of support such as response to intervention (RTI) and positive behavioral interventions and supports (PBIS). This authoritative work provides a complete guide to implementing a wide range of problem­-solving assessment methods, including: (1) functional behavioral assessment; (2) interviews; (3) classroom observations; (4) curriculum-­based measurement; (5) rating scales; and (6) cognitive instruments. Prominent experts demonstrate the key role of assessment throughout the process of supporting at-­risk students, from identifying academic and behavioral problems to planning and monitoring interventions. Several chapters include reproducible forms that can be downloaded and printed. This updated second edition: (1) Reflects current education policy and best practices; (2) Contains an updated chapter on problem solving by Stanley Deno, including a revised model; (3) Discusses assessment in the context of multi-­tiered systems of support in each chapter; and (4) Features a new chapter on working with culturally and linguistically diverse learners, and a new chapter on graphing student data.
