> California State Bar Law Office Study Program The California State Bar Law Office Study Program allows California residents to become California attorneys without graduating from college or law school, assuming they meet basic pre-legal educational requirements.[19] (If the candidate has no college degree, he or she may take and pass the College Level Examination Program (CLEP).) The Bar candidate must study under a judge or lawyer for four years and must also pass the Baby Bar within three administrations after first becoming eligible to take the examination. They are then eligible to take the California Bar Examination.
