HB 2129 modifies Tennessee's reporting requirements for pre-kindergarten programs by changing the frequency from annual to triennial (every three years). The bill directs the Department of Education's Office of Early Learning to submit a detailed report to the governor and legislature every three years, including data on provider locations, program types, and the number of at-risk children served. The report must also be published on the department's website. This change directly affects the Department of Education's Office of Early Learning, altering its administrative reporting obligations.
