Tennessee Investment in Student Achievement (TISA) - As introduced, revises the weighted allocations generated by a student for purposes of the TISA based on the number of student members of the LEA in which the student resides; establishes a $50 direct allocation for each student member of each LEA to assist each LEA with maintenance and infrastructure. - Amends TCA Title 49, Chapter 3.

SB 426 (Tennessee Investment in Student Achievement, or TISA) adjusts how Tennessee funds public school districts based on their size. It revises weighted funding allocations for districts with 1,000-4,999 students - assigning higher percentages to smaller districts (e.g., 1,000-1,999 students receive 4% instead of the previous 5%). The bill also adds a new $50 direct allocation per student for each district’s maintenance and infrastructure, effective for the 2025-2026 school year. These changes directly affect all Tennessee school districts (LEAs) by altering their state funding formula and providing dedicated resources for physical facilities.
