The U.S. Department of Education (ED) has released determination letters on state implementation of the Individuals with Disabilities Education Act (IDEA), Parts B and C. States participating in Part B, which serves individuals age 3-21, and Part C, which serves infants and toddlers birth through age 2, are scored against four ratings based on the state’s performance on its State Performance Plan (SPP): Meets Requirements; Needs Assistance; Needs Intervention; and Needs Substantial Intervention. According to analysis provided by The Advocacy Institute of the determination letters on Part B performance, when compared to 2025, ratings improved for four states: AL, FL, RI, SD; ratings dropped for seven states: ME, MD, MN, NM, NY, ND, VT; and just 5 states have received a “Meets Requirements” rating each of the past 13 years (2014-2026): KS, MA, MO, PA, WI. COPAA member Candace Cortiella and founder of The Advocacy Institute has analyzed the letters and provided map of state ratings.
