The 2011 accountability data tables employ masking of assessment data,
in order to comply with the federal Family Educational Rights and
Privacy Act (FERPA). Generally speaking, the term "masking"
refers to the use of special symbols to conceal the performance results.
TAKS, TAKS Commended Performance, and English Language Learners (ELL) Progress Indicator results are masked under the following conditions:
 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.
 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 TAKS results are 100 percent or round
to 100 percent, then the expression >99% is shown. In cases
where 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 2011 accountability 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.

In summary for there to be no masking of assessment data, all
of the following conditions must be met:
 Denominator is five or more (ten or more on the TAKS Progress
Indicator under AEA Procedures); 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.
