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.

Alfreda Soriano's Response:

Your grading system looks almost identical to the individual Language Arts and Math report cards that are routinely sent to teachers each school year. Even the color bar graph is the same, but I think the numerical gradations are missing.

I do believe that the teacher is the single most important factor is a child's education, but I know that parental support is also a critical factor. All students are not equal, so comparing the scores of a class of gifted and high achieving students with the scores of those students at the opposite end of the spectrum seems blatantly unfair as a measure of teacher effectiveness. The teacher with the students at the bottom end of the spectrum must, on a daily basis, work many times harder to teacher his/her students.

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.

Do the ratings in this database reflect your experience or your child's experience in the teacher's classroom? Do you believe this is a helpful tool for parents?
