About MHACBO, est. 1977

The Mental Health and Addiction Certification Board of Oregon (formerly ACCBO) was founded in 1977 with the mission of certifying behavioral health professionals through competency-based evaluation of education, experience, and exams. The Board utilizes autonomous professional psychometric examinations through CES (Comprehensive Examination Services), NAADAC (National Association of Alcoholism and Drug Abuse Counselors) and the IC&RC (International Certification Reciprocity Consortium). The primary purpose of certification is an assurance that behavioral health workers have met minimum standards of competence, are ethically accountable to the general public at-large, and have contemporary knowledge evidenced through continuing education.
