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.

Sharon Dornberg's Response:

I teach at a math/science gifted/high achievement magnet where the students are expected to score well. When we had the norm reference test CAT6 we could see the true extent of our students and get a better idea of where to improve our instructions. On a criteria reference test CST it is difficult because our students will always score well because there is no way of showing the results of the enrichment and the push beyond grade level. When 88% of my 48 students (I team teach with another teacher, I teach the math and science) score advanced in math, I am still shown as an average teacher. I have an NBC, Bilingual/Bicultural competency certificate (a forerunner of the bilingual credential), and am the lead support provider in LD8 for the BTSA program. But according to your results I am an average teacher.

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?
