Colorado Mandates Universal K-3 Dyslexia Screening

Senate Bill 200, signed into law in May 2025, amends Colorado’s READ Act to require universal dyslexia screening for all kindergarten through third grade students starting in the 2026-27 school year. The legislation takes a comprehensive approach: all K-3 teachers must receive training in screening administration and result interpretation, and any student showing risk factors receives a diagnostic assessment within 60 days, followed by a READ learning plan with dyslexia considerations.

Districts can choose between adopting an approved screener or creating a local screening process by fall 2027. Rachel Arnold, president of the Rocky Mountain branch of the International Dyslexia Association, notes that some districts had already begun implementing free dyslexia screeners before the legislation passed. “We just wanted to see, if we had universal screening and screened all kindergarteners for dyslexia, would there be children that we would have missed if we had just relied on existing benchmarks,” Arnold explained. “We found that was yes.”

The legislation received bipartisan support, with sponsorship from both Republican and Democratic legislators. According to the Rocky Mountain IDA, between 15 and 20 percent of the population processes print differently, though a large portion of these individuals often go unidentified through traditional assessment methods.
