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 modifies Tennessee law to reduce the state funding limit for school nurses from $3,000 to $750 per student. The change directly affects school districts that rely on state allocations to hire or support nursing staff. By lowering the maximum allowable funding amount, the legislation reduces the financial resources available for school health services. The act amends specific sections of the state code to reflect this new cap and takes effect immediately upon becoming law.
