Tennessee Investment in Student Achievement (TISA) - As enacted, makes changes to the law relative to TISA funding for school nurses or school health services. - Amends TCA Title 49 and Title 68.

This bill, known as the Tennessee Investment in Student Achievement (TISA) amendment, adjusts the funding threshold for school nurses within Tennessee public schools. Specifically, it lowers the student population limit from 3,000 to 750 students, meaning districts with fewer than 750 students now qualify for TISA funds to support school health services. By amending state law, the legislation directly impacts how smaller school districts allocate resources for nursing staff and related health programs. The change ensures that smaller schools receive financial support for these essential services under the existing TISA framework.
