Tennessee Investment in Student Achievement (TISA) - As introduced, increases, from $200 to $500, the amount each LEA and public charter school is required to pay each teacher in kindergarten through grade 12 for the purchase of instructional supplies. - Amends TCA Title 49, Chapter 3.

SB 184 increases the required annual payment for instructional supplies from $200 to $500 per teacher in Tennessee's public K-12 schools and public charter schools. It amends Tennessee Code Annotated § 49-3-359(a) to mandate this higher funding level for local education agencies (LEAs). The bill explicitly states it does not create new spending, requiring future legislative appropriations to fund the increase. The change would take effect July 1, 2025, if enacted. This directly affects school districts and charter schools responsible for distributing these supplies to teachers.
