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.

HB 88 increases the annual requirement for Tennessee public schools and charter schools to provide teachers with funds for classroom supplies, raising the amount from $200 to $500 per K-12 teacher. This change directly affects all local education agencies (LEAs) and public charter schools by mandating a higher per-teacher supply allowance. The bill amends Tennessee Code § 49-3-359 to reflect this funding increase but clarifies that no funds will be spent unless specifically allocated in the state budget. The policy change would take effect on July 1, 2025, pending legislative appropriation.
