The Reading Universe Taxonomy

Our taxonomy is a scope and sequence for teaching all the skills needed for fluent reading. This interactive tool shows how the major skills are connected — including word recognition, language comprehension, reading comprehension, and writing — and breaks the instructional process down into manageable pieces. Use it as a roadmap for ensuring students get all of the necessary, research-backed skills.
