Education - As enacted, requires the department of education to establish enrollment deadlines for voluntary pre-kindergarten programs so that at-risk students who will be four years old by August 15 must be enrolled by the beginning of the school year and students who are four-year-olds who do not have a disability or who meet the qualifications for enrollment at three years of age must be enrolled by August 30. - Amends TCA Title 49.

HB 623 sets specific enrollment deadlines for Tennessee's voluntary pre-kindergarten programs. It requires the state education department to establish two deadlines: at-risk students turning four by August 15 must enroll by the start of the school year, while other four-year-olds (without disabilities or qualifying at age three) must enroll by August 30. The bill directly affects families and local schools offering pre-K, ensuring consistent enrollment timing for these student groups. Key provisions mandate the department to create these deadlines, applying to the 2025-2026 school year and beyond. This policy change standardizes enrollment windows without altering program eligibility criteria.
