Citations are quoted from California Department of Social Services inspection and complaint reports. Type A citations are the state’s most serious category (an immediate risk to children’s health, safety or personal rights); Type B citations are a potential risk. A citation is a finding about one rule, not a judgment about a center overall. Complaint allegations appear here only when the state substantiated them.
