Acadience Reading Diagnostic: Comprehension, Fluency, and Oral Language Assessment (CFOL) is an individually administered diagnostic assessment published by Acadience Learning for students in kindergarten through sixth grades. The measure purportedly provides diagnostic information in story coherence/text structure, listening and reading comprehension, vocabulary and oral language, and fluency with expository and narrative texts. The skills assessed with the CFOL are designed to provide information about skills related to students' comprehension difficulties so educators can better target comprehension interventions to support students' specific learning needs.
