HB 351 seeks to implement an annual inflation adjustment to the basic allotment for school funding under Texas' Foundation School Program. Starting in the 2026-2027 school year, this adjustment will either be a 3% increase from the previous year or an increase based on the Consumer Price Index (CPI), as determined by the Texas Comptroller, whichever is lower. Additionally, if inflation is negative, the increase will be zero. The bill allows the Texas Legislature to set a lower amount than calculated, provided it does not fall below the existing base funding amount.
