To be clear, very few people become licensed lawyers in CA taking this path. The vast majority can't pass the Bar and the state often goes years without a single person passing via the apprenticeship track.
Oh sure, I was referring primarily to people who attend non-accredited law schools. There are several law schools that are not ABA-accredited but that are CA-accredited. There are a few more that are not accredited by either. The apprenticeship track is probably less popular than either of these routes, although recently it's been made famous by Kim Kardashian.
