Relating to the definition of "eligible school district" for purposes of the study of school district property values conducted by the comptroller of public accounts.

HB 121 amends Texas law to define which school districts qualify for a property value study conducted by the comptroller. An "eligible school district" must have had invalid local property values (but not exceeding state values) in the most recent study, while maintaining valid local values in the two prior studies. The bill does not change the study process but sets specific eligibility criteria based on historical valuation compliance. This definition applies only to studies for tax years starting on or after January 1, 2026.
