The Flynt/Cooter Comprehensive Reading Inventory-3 (CRI-3) is an evidence-based informal reading inventory for assessing the five components of reading in PreK-12 classrooms and research. It offers a straightforward miscue analysis method for assessing students’ levels of competency in reading comprehension and fluency as well as easily administered assessment tools for discerning students’ development in phonemic awareness, phonics, and vocabulary. Updated to incorporate the latest evidence-based literacy research and best practices in assessment, the new format includes an Examiner’s Manual and reusable Student Booklet that allows teachers to administer assessments more quickly while reducing the need for printing and photocopying.
