The following domains are included in CFOL: story coherence/text structure, listening and reading comprehension, vocabulary and oral language (e.g., formal definitions, morphological awareness, figurative language, syntax), and fluency with expository and narrative texts. These relatively brief diagnostic assessments are cost- and time-efficient, yet comprehensive enough to provide specific information to better target or differentiate instruction for students who are struggling in their reading development. The measures are untimed and designed to be user-friendly and adaptable across instructional settings.
