K-3 reading program; curriculum requirements

HB 2021 establishes Arizona's K-3 reading program to improve early literacy for students in kindergarten through third grade. It requires school districts and charter schools to develop annual reading improvement plans, ensure at least one teacher per school receives dyslexia training, and use state funding (from the "K-3 reading support level weight") exclusively for evidence-based reading instruction. The bill mandates annual reporting on program results, including student reading proficiency data and spending, and prioritizes support for schools with higher percentages of struggling readers. It directly affects K-3 public school students, teachers, and school districts by setting specific curriculum, training, and funding requirements.
