Colorado Requires Reading Screening for Every Young Student

Colorado’s Senate Bill 200, signed into law in May 2025, directly amends the state’s READ Act to require universal dyslexia screening for all kindergarten through third-grade students beginning in the 2026-27 school year. Districts can choose between adopting an approved screener or creating their own local screening process, but all K-3 teachers must receive training in both screening administration and result interpretation by fall 2027.

When screening reveals risk factors, schools must complete a diagnostic assessment within 60 days and develop a READ learning plan that considers how the child processes print. Rachel Arnold, president of the Rocky Mountain branch of the International Dyslexia Association, explained that several districts had already begun implementing free screening before the mandate. Research shows that 15 to 20 percent of children develop reading differently, yet most go unidentified until they’ve already internalized years of academic struggle.

The legislation builds on Colorado’s existing READ Act, which already required screening for learning differences in younger students. But Arnold noted that even with those earlier supports, data showed schools were missing children who would benefit from targeted intervention. Universal screening eliminates the gatekeeping that kept many families waiting years for answers.
