If after conducting the annual study for a tax year the comptroller determines that the local value for a school district is not valid, the comptroller shall adjust the taxable value determined under Subsections (a) and (b) as follows: (1) for each category of property sampled and tested by the comptroller in the school district, the comptroller shall use the weighted mean appraisal ratio determined by the study, unless the ratio is more than four percentage points lower than the weighted mean appraisal ratio determined by the comptroller for that category of property in the immediately preceding study, in which case the comptroller shall use the weighted mean appraisal ratio determined in the immediately preceding study minus four percentage points; (2) the comptroller shall use the category weighted mean appraisal ratios as adjusted under Subdivision (1) to establish a value estimate for each category of property sampled and tested by the comptroller in the school district; and (3) the value estimates established under Subdivision (2), together with the local tax roll value for any categories not sampled and tested by the comptroller, less total deductions determined by the comptroller, determines the taxable value for the school district.
