1. When very few students in the group are assessed.
   If performance is revealed for a group of very few students, then it is possible that the result for an individual student could be known, which violates that student's right to privacy.
   
2. When all students have the same result (for example, either all passing or all failing).
   Revealing that 100 percent of the students passed or 0 percent passed has been deemed to violate the privacy of all students tested in that the result for every student tested is known. In cases where STAAR or TAKS results are 100 percent or round to 100 percent, then the expression >99% is shown. In cases where STAAR or TAKS results are 0 percent or round to 0 percent, then <1% is shown.

The tables below show each of the masking situations that are possible on the 2012 AYP data tables. Note that an asterisk ('*') is used for a number of different conditions. The symbols in the shaded bars (rows with case labels) will appear on the reports in place of the data shown in the examples.

• Denominator is five or more and,
• Number passing is more than two; and,
• Number failing is more than two; and,
• Percent is not 100 or 0 and does not round to either 100 or 0.
