Relating to reading instruction, assessment instruments, and interventions provided to public school students.

HB 3583 requires Texas public school districts and open-enrollment charter schools to use research-based reading assessment tools for students in kindergarten through grade three. The bill limits schools to administering reading assessments no more than three times per school year and mandates that approved tools must cover foundational literacy skills (like phonemic awareness and phonics), diagnose reading difficulties, and guide targeted instruction. The Texas Education Commissioner must adopt a list of approved instruments meeting specific criteria, including progress monitoring and identifying students needing intervention. This directly affects K-3 students and school staff implementing reading assessments.
