Superintendent Ramon C. Cortines said an approach called "value added" would tie student test scores to teacher evaluations, the Los Angeles Times reported Thursday.
That approach isn't popular, and the teachers union must approve the proposal, the report said.
Cortines outlined the proposal in a meeting of administrators Wednesday, and said he wants the rating to account for 30 percent of a teacher's evaluation.
The superintendent also said he was disappointed California did not qualify for an estimated $700 million in funding from a federal school improvement plan called Race to the Top. The district's portion of those funds would have been $153 million.
Race to the Top winners were announced Tuesday. However, Cortines said he learned Tuesday the district would receive $52 million in unrelated federal grants.
