The school may have cleaned its act up some, but one wonders how much. The "primary counseling staff" are all "certified" by ACSTH, which is linked to Narconon (a known Scientology "brand name"), and which lists its business address as being in the same building as the L. Ron Hubbard Library on Hollywood Boulevard.
Private agency (as opposed to government agency) certification is typical in the substance abuse field. The better-regarded CAADAC certification is given by a private agency, after a two-year course at a public junior college. But as is the case with the ACSTH "life counselor" certification (following a much less rigorous course of study than for the CAADAC), it is recognized by the state of California.
Benchmark operates under state Dept. of Consumer Affairs licensure as a "California Sober Living Program." The CSLP is, in my direct experience, very poorly monitored by the CDCA, which really doesn't monitor so much as it responds to inquiries, investigations and consumer complaints. CSLP is actually fairly typical of mental health oversight in general: it's not proactive.
All that said, Benchmark is no worse in my indirect experience than are many of the residential mental health facilities in this region, and actually quite a bit better than a number of them. Sigh.
