California Code, Education Code - EDC § 51410

No diploma, certificate or other document which is conferred upon a pupil as evidence of his completion of a prescribed course of study or training shall bear any distinctive marking or words which indicate that the pupil upon whom it was conferred was, for purposes of his course of study or training, placed within a particular classification based upon his intellectual or mental capacity.

The provisions of this section shall not be construed to prevent a diploma, certificate or other document from indicating that the pupil upon whom it is conferred maintained exceptionally high grades during his course of study or training, or that he completed his course with honors, or to prevent the governing board of any school district from publicizing such information.
