These graphs show a teacher's "value-added" rating based on his or her students' progress on the California Standards Tests in math and English. The Times’ analysis used all valid student scores available for this teacher from the 2002-03 through 2008-09 academic years. The value-added scores reflect a teacher's effectiveness at raising standardized test scores and, as such, capture only one aspect of a teacher's work.

Robert Moore's Response:

"Value-added models provide important information, but that information is error-prone
and has a number of other important limitations. Moreover,
these methods are still under development, and the various
approaches now in use do not always paint the same picture.
Value-added estimates can be an important part of an evaluation
of teachers and schools, but they are not sufficient by themselves
for this purpose.” –David Koretz

The Times gave LAUSD elementary school teachers rated in this database the opportunity to preview their value-added evaluations and publicly respond. Some issues raised by teachers may be addressed in the FAQ. Teachers who have not commented may do so by contacting The Times.
