Tax Code Section 5.10 requires the Comptroller's office to conduct a ratio study to measure the performance of each appraisal district in Texas at least once every two years and to publish the results.
The purpose of the Appraisal District Ratio Study is to measure the uniformity and median level of appraisals performed by an appraisal district within each major category of property.
To conduct the Appraisal District Ratio Study, the Comptroller’s office applies appropriate standard statistical analysis techniques to data collected through the school district property value study required by Government Code Section 403.302.
The published report provides ratio study results for each appraisal district studied that year and includes:
