Education - As enacted, creates an advisory committee on innovations in K-12 education. - Amends TCA Title 8 and Title 49.

HB 675 amends Tennessee education law to change how teachers and principals are evaluated. It requires 60% of their evaluations to be based on student achievement data - 35% from growth measures like the state’s TVAAS system and 25% from other approved metrics, with teachers/principals agreeing on the specific measures used. The bill directly affects all public school teachers and principals in Tennessee, impacting decisions about their promotion, retention, and compensation. Key mechanisms include rules for challenging evaluation accuracy, using alternative growth models for non-tested subjects, and ensuring evaluations align with teaching assignments. (Note: The bill’s title mentions an advisory committee, but the actual provisions focus on evaluation rules, not committee creation.)
