California Code, Education Code - EDC § 94355

(a) As a condition of doing business in this state, each postsecondary educational institution governed by Chapter 7 (commencing with Section 94700), and each organization that administers educational testing for use in the admissions process by any public or private postsecondary educational institution, shall, in administering any test or examination, permit any student who is eligible to undergo the test or examination to do so, without penalty, at a time when that activity would not violate the student's religious creed.

(b) This requirement shall not apply in the event that administering the test or examination at an alternate time would impose an undue hardship which could not reasonably have been avoided.  In any court proceeding in which the existence of an undue hardship that could not reasonably have been avoided is an issue, the burden of proof shall be upon the institution.

(c) This section shall become operative on January 1, 1997.
