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: functional behavioral assessment, interviews, classroom observations, curriculum-based measurement, rating scales, and 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 in a convenient 8 ½ x 11 size.
