Colorado Mandates Early Reading Screening

Colorado Senate Bill 200, signed into law May 23, 2025, requires all public schools to conduct universal dyslexia screening for kindergarten through third grade students beginning in the 2027-28 school year. The legislation expands the state’s existing READ Act to include specific screening for characteristics associated with dyslexia—including difficulties with sound-symbol relationships, word decoding, and phonological awareness—within the first 90 days of school for first through third graders and the last 90 days for kindergarteners.

Districts can choose between adopting a state-approved screener or creating their own screening process that meets bill criteria. When risk factors appear, schools must conduct diagnostic assessments within 60 days and develop targeted intervention plans. Rachel Arnold, president of the Rocky Mountain branch of the International Dyslexia Association, notes that early data from pilot districts showed universal screening identified children who would have been missed by existing benchmarks alone.

The law builds on grassroots momentum from communities like those in Eagle and Summit counties, where 80 parents and children gathered in November for a dyslexia awareness event at Vail Mountain School—wearing red to symbolize the corrections that mark so many struggling readers’ papers.
