Explanation of 2017–18 TAPR Masking Rules

The 2017–18 Texas Academic Performance Reports (TAPR) and Downloads employ masking of performance data in order to comply with the federal Family Educational Rights and Privacy Act (FERPA). Generally, the term "masking" refers to the use of special symbols to conceal the performance results.

The tables below show each of the masking situations that are possible on the reports. Different rules apply for the STAAR indicators compared to other performance indicators. STAAR performance has three levels: the Approaches, Meets, and Masters Grade Level. The Masters Grade Level numerator will trigger the masking of all three numerators and rates if there are 0 – 4 tests for the Masters Grade Level numerator.
