Employment services combine a variety of pre-employment, job development and post-employment services to maximize a successful job match and job retention. Specific programs are typically designed to serve a defined population or group of people (e.g. referrals from the Department of Mental Health & Addiction Services(DMHAS), the Bureau of Rehabilitation Services (BRS), the Department of Social Services (DSS), the Department of Developmental Services (DDS), or persons with a history with the Department of Correction (DOC) and are staffed with appropriately qualified personnel.
