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.

Christina Riggs's Response:

Looking at data is crucial to effective teaching. After my first year of teaching, I was able to examine the CST data from that first class to see that my teaching was ineffective. I was therefore able to change elements of my practice to become much more effective the following years as a fourth grade teacher. Unfortunately, data from the 09-10 school year is not included in these results. I am interested in seeing a growth model for teachers over their years of teaching. For example, rating teachers on their effectiveness on separate graphs for each of the last five school years to see growth over time.
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.
