Universal Screening Comes to Colorado Schools

Colorado Governor Jared Polis signed Senate Bill 25-200 into law in May 2025, making the state one of the latest to require universal dyslexia screening for all students in kindergarten through third grade. Starting with the 2027-28 school year, every Colorado school district must either develop its own screening process or adopt a universal screener that meets state criteria. The bill also mandates that all K-3 teachers receive training in screening administration and result interpretation.

The legislation addresses a significant gap in early identification. According to the Colorado Department of Education, approximately 15 to 20 percent of the population experiences reading differences consistent with dyslexia, making it the most commonly identified learning difference. Before this law, Colorado was one of only seven states without mandatory screening, leaving many children unidentified until performance gaps widened—typically between third and fourth grade, when intervention becomes more challenging.
