This trusted text and teacher resource is now in a revised and updated fifth edition, reflecting key advances in the science of reading. It covers the “whys,” “whats,” and “how-tos” of systematic reading assessment in grades K–8. The authors provide a roadmap and practical tools for evaluating students’ strengths and needs in each component of reading, resulting in a seamless integration of assessment, evidence-based instruction, and intervention. Essential topics include evaluating the comprehension of beginning readers, assessing older struggling readers, supporting English learners, and preparing diagnostic reading reports. In a convenient large-size format, the book includes 30 reproducible and downloadable tools, plus an online-only appendix with an additional multipage assessment.
