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 2003-04 through 2009-10 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.

About this rating

The red lines show The Times’ value-added estimates for this teacher. Butts falls within the “most effective” category of district teachers in math and within the “most effective” category in English. These ratings were calculated based on test scores from 130 students.

Because this is a statistical measure, each score has a degree of uncertainty. The shading represents the range of values within which Butts’s actual effectiveness score is most likely to fall. The score is most likely to be in the center of the shaded area, near the red line, and less likely in the lightly shaded area. Teachers with ratings based on a small number of student test scores will a have wider shaded range.

The beige area shows how the district's 11,500 elementary school teachers are distributed across the categories.

Steven Butts's Response:

Just a thought
How about publishing the names of the highly effective and effective teachers only. This would recognize the successes of those teachers, and also let parents know if their son's or daughter's teacher were not in the top brackets. I've never once posted my students' scores on the board for all to see, as I don't believe that public humiliation brings about positive change (not in the classroom, not in sports, and not in the job world). I do however believe that more positive recognition for the successful teachers would encourage all teachers to strive for excellence and seek the guidance from those who have proven results year after year.


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.
