California Code, Education Code - EDC § 76224

(a) When grades are given for any course of instruction taught in a community college district, the grade given to each student shall be the grade determined by the instructor of the course and the determination of the student's grade by the instructor, in the absence of mistake, fraud, bad faith, or incompetency, shall be final.

(b) No grade of a student participating in a physical education class, however, may be adversely affected due to the fact that the student does not wear standardized physical education apparel where the failure to wear such apparel arises from circumstances beyond the control of the student.
