Colorado Implements Universal K-3 Screening

Starting in the 2026-27 school year, Colorado will require all public schools to screen kindergarten through third grade students for dyslexia under Senate Bill 200, signed into law by Governor Jared Polis in May 2025. The legislation builds on the state’s existing READ Act by adding universal dyslexia screening requirements that earlier mandates missed. Districts can choose from state-approved screening tools or develop their own local processes, with all K-3 teachers required to complete training in screening administration and result interpretation by fall 2027.

When screening identifies risk factors, districts must provide a diagnostic assessment within 60 days, followed by a READ learning plan that considers dyslexia-specific needs. The Colorado Department of Education is finalizing implementation guidance, with detailed rules expected when the State Board of Education meets this summer. Rachel Arnold, president of the Rocky Mountain branch of the International Dyslexia Association, explains that early universal screening reveals children who would have been missed by existing benchmarks alone.
