Five hundred Field Services deputy probation officers "investigated 25,000 adult and 16,500 juvenile cases each year and supervised 24,500 adult and 15,000 juvenile probationers from 11 area offices," and an additional hundred deputies "worked with almost 1,000 boys in 10 camps." In 1961, the California State Legislature adopted juvenile court reform laws, following recommendations from the Governor's Commission, in the first major reform since 1903.
