Comparable Improvement (CI) is a measure that shows how student
performance on the TAKS reading/ELA and mathematics tests at a given
school has changed (or grown) from one year to the next, and then
compares that change to that of the 40 schools that are demographically
most similar to the given, or "target" school.
From this web page you can access a school's comparison group to
see a list of the 40 schools most similar to the school, as well
as the performance growth of each school on that list. Simply go
to the Campus Group and CI Report.
These 2-part reports are calculated for every school in the state,
along with their AEIS reports every year. An explanation of the
grouping methodology and Comparable Improvement can be found in
the AEIS Glossary.
Two other items are available through this web page: the District
Summary (in PDF and HTML format) provides a list of
all the schools in a district with their CI quartiles; and the Quartile
Summary provides an analysis of the quartile positions
of the 40 schools in a target school's group.
Please note that comparison groups and CI are calculated only for
schools, not districts.
