This book provides a practical guide to curriculum-based evaluation (CBE), which helps educators solve learning problems by making data-based decisions about what and how to teach. CBE offers clear procedures for analyzing PreK-12 students' academic skills, determining where instruction needs to focus, and evaluating progress. Written in an engaging, step-by-step style, the book features examples throughout that illustrate the problem-solving process. The use of curriculum-based measurement (CBM) as a data collection technique is discussed. Reproducible planning and implementation tools are included; the large-size format facilitates photocopying. Purchasers also get access to a Web page where they can download and print the reproducible materials. This book is in The Guilford Practical Intervention in the Schools Series, edited by Sandra M. Chafouleas. See also The ABCs of CBM: A Practical Guide to Curriculum-Based Measurement, by Michelle K. Hosp, John L. Hosp, and Kenneth W. Howell, which provides hands-on instructions for implementing a core technique used in CBE.
