The 2011-12 AEIS reports employ masking of performance 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 is masked under the following conditions:
- When very few students in a 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 pass or all students fail. Revealing
that 100 percent of the students passed or 0 percent passed
is considered to be a violation of the privacy of all students,
because the result for every student tested is known. In cases
where TAKS is 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 2011-12 AEIS Reports. Different rules apply
for the TAKS indicators compared to other performance indicators.

Symbols Used for Masking Campus Comparison Group Values
- If the campus group median value is based on 16 or fewer campuses,
an asterisk (*) is reported and a -1 is stored on the download
file.
- If the campus group value does not exist at all, a dash (-)
is reported and a period (.) is stored on the download file.
Symbols Used for Masking Profile Values
If values reported on school and district staff, finances, and
student demographics are outside a reasonable range, a question
mark (?) is printed on the report and a -2 is stored on the download
file.
