Sandra Colloca's Response:

My name has not been on class CST roster for past 3 years as I am part-time and my partner's name is recorded. I was also part-time years prior (TEACHING KINDERGARTEN in 2005 which is not tested). I taught full time in 2006 when most of my students' CST scores improved, as analyzed with my administrator during my stull conference. I would be very interested to see a more detailed break-down of analysis to see how score was determined. According to FAQ to right, complications ("errors") in LAUSD data reporting (split classes, departmentalization, part time)may cause "unusual results".

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?
