TISA Impact on Districts

TISA's impact varies dramatically depending on a district's size, demographics, and local tax base. Urban districts with large populations of economically disadvantaged students and English learners generally see increased funding under TISA compared to the BEP. The weighted allocations for these student groups were minimal under the old formula but are substantial under TISA, directing significantly more money to the districts that serve the highest-need students.

Suburban districts present a more mixed picture. Many of these districts have relatively affluent student populations that generate fewer weighted dollars, but they also have strong local tax bases that reduce their state share. Some suburban districts are essentially flat, receiving roughly the same total funding under TISA as they did under the BEP. Others see modest increases, particularly if they have growing populations of English learners or students with disabilities.

Rural districts face the most uncertainty. Tennessee's rural counties often have shrinking populations, limited local tax revenue, and high fixed costs for transportation and facilities. Under a student-based formula, fewer students means less funding, even if the cost of running a school building or a bus route does not decrease proportionally. The hold-harmless provision provides a temporary buffer, but rural superintendents are planning for a future where every lost student means a real reduction in revenue.

One area where TISA has had an immediate and visible impact is in special education funding. The BEP provided a flat allocation for special education that did not differentiate between a student with mild learning disabilities and one who requires full-time support. TISA uses a tiered weight system that provides significantly more funding for students with intensive needs. Districts with large special education populations have seen meaningful increases in their allocations.

Charter schools also felt the impact of TISA. The formula includes a specific facilities weight for charter schools, acknowledging that they do not have access to local capital funding in the same way traditional public schools do. This provision was controversial, with some traditional public school advocates arguing it diverts money from existing buildings, while charter supporters argued it levels a longstanding inequity in how facilities are funded.
