Cal. Educ. Code § 69743

The program is intended to supplement, and not to replace, existing loan repayment programs operated by law schools. Prior to participating in the program, an applicant shall apply for any educational loan assistance from his or her educational institution for which he or she may qualify. Only if an applicant has received no loan repayment assistance, or only partial assistance, from other available sources, may he or she apply to the program for assistance in repaying the balance of his or her educational loans.
