Education and Experience Requirements

Illinois offers four certification levels for substance abuse counselors: certified alcohol and drug counselor (CADC), certified reciprocal alcohol and other drug abuse counselor (CRADC), certified supervisor alcohol and drug abuse counselor (CSADC), and certified advanced alcohol and other drug abuse counselor (CAADC).

While some Illinois certifications don't require a college degree, advancement in the addictions field increasingly requires postsecondary training. The following sections describe the academic and experience requirements to become a substance abuse counselor in Illinois.

Academic Requirements

Educational requirements for substance abuse counselors in Illinois vary by the type of certification. While CADC, CRADC, and CSADC credentials only require a high school diploma or GED, an associate or bachelor's degree reduces the practical experience requirements of these credentials. Candidates for the CAADC credential, the highest level of certification in the state, need a master's degree in a behavioral science, such as counseling, social work, psychology, or marriage and family therapy, that includes a supervised clinical application.

Substance Abuse Counseling Coursework

Most drug and alcohol counseling bachelor's degrees require 120 semester credits, while a master's degree usually comprises 60 credits. Undergraduate courses vary by program but typically include classes in case management, causes and treatment of addictive behavior, pharmacology, and group counseling. Some schools structure their curriculum to fit the core competencies recommended by the Substance Abuse and Mental Health Service Administration. Coursework in a master's program often addresses professional development and ethics, the social and cultural context of counseling, and specialized substance abuse topics.

Practicum and Supervised Practice

All substance abuse programs require students to participate in supervised field experiences or practicums. Most bachelor's programs require 350 hours of clinical work, while master's programs may require several hundred additional hours of supervised clinical experience. The more clinical hours that a student completes during a degree program, the fewer supervised work hours they need for Illinois certification.

The Exam and Application Process for Illinois Substance Abuse Counselors

This section describes the four levels of certification administered by The Illinois Certification Board (ICB): the basic CADC, and three certificates issued in partnership with the International Certification and Reciprocity Consortium (IC&RC). All certificates require a criminal background check. ICB charges a $75 application fee and a $175 examination fee for each credential.


Requirements include a high school diploma or GED, 4,000 hours of paid counseling experience over the past four years, and 150 hours of supervised practical experience. In addition to passing the CADC examination, applicants must complete 225 training hours on treatment services for women, adolescents, and their families; professional ethics; and performance domains that cover professional responsibility, counseling, case management, client education, and assessment.


While this certificate does not require college credits, an associate or higher degree reduces the total required supervised practical work hours. All applicants must complete 300 training hours and pass the state-administered CRADC exam and the IC&RC reciprocal exam.


Applicants need CRADC certification and 10,000 hours of counseling experience within the past seven years, including 300 hours of supervised practical experience and 350 training hours in treatment services, professional ethics, clinical supervision, and state performance domains. Candidates must pass the CADC Illinois exam, the IC&RC supervisor exam, and the IC&RC reciprocal exam.


CAADC requires a master's degree in a behavioral science from an accredited school. Applicants must complete 2,000 hours of paid counseling work, 2,000 hours as a clinical supervisor, 300 hours of supervised practical experience, and 180 training hours in treatment services and professional ethics. Certification requires a passing score on the IC&RC AODA exam.

Out-of-State Substance Abuse Counselor Candidates

Addiction professionals certified by IC&RC member boards in other states may apply for equivalent credentials from the ICB. Illinois does not require retesting. IC&RC charges a $100 certification fee to transfer the credential to Illinois. The new credential will have the same expiration date as the previously earned certificate.

Each jurisdiction uses different terminologies for their credentials. The Illinois reciprocal alcohol and other drug abuse counselor credential corresponds to the IC&RC alcohol and drug counselor credential, while the certified supervisor alcohol and other drug abuse counselor credential is equivalent to the IC&RC clinical supervisor credential.

Substance Abuse Counselor License Maintenance and Renewal Requirements

ICB requires all certified substance abuse counselors to renew their certification every two years. Renewal costs $140-$190, depending on the level of certification. Counselors seeking recertification must submit evidence of completing 40 ICB-approved continuing education units within the two-year certification period. Candidates must acquire an average of 20 CEUs each year to maintain certification. ICB awards 15 CEUs for one semester hour of college credit, 12 CEUs for one college trimester hour of credit, and 10 CEUs for one quarter hour of college credit.
