A CADC, or Certified Alcohol and Drug Counselor, is a professional credential that qualifies you to provide substance use disorder counseling. It’s one of the most widely recognized certifications in the addiction treatment field, covering everything from screening and assessment to individual and group therapy. The specific requirements vary by state, but the credential generally involves a combination of education hours, supervised clinical experience, and passing a standardized exam.
What a CADC Does
A CADC works directly with people struggling with alcohol and drug use disorders. The scope of practice is broader than many people expect. It includes conducting clinical evaluations and screening for substance use disorders, developing treatment plans (including relapse prevention), providing individual and group counseling, coordinating care with other providers, and educating clients and their families. Trauma-informed care is also part of the role, reflecting the strong overlap between addiction and past trauma.
CADCs work in a range of settings: outpatient substance abuse centers, residential treatment facilities, hospitals, community mental health agencies, and programs that combine medication-assisted treatment with behavioral therapy. Some work in correctional facilities or employee assistance programs. The median annual wage for substance abuse, behavioral disorder, and mental health counselors was $59,190 in May 2024, according to the Bureau of Labor Statistics. Pay varies by setting. Hospital-based positions averaged about $61,930, while residential treatment facilities came in lower at around $49,610. The top 10% of earners made more than $98,210.
Certification Tiers and Levels
Most states offer multiple tiers of CADC certification, typically labeled CADC-I, CADC-II, and in some states CADC-III. The tiers reflect increasing levels of education and clinical experience. A CADC-I generally requires the most supervised work hours (up to 6,000 in some states) because the educational requirements are lower. A CADC-II typically requires fewer supervised hours (around 4,000) paired with more formal education. At the CADC-III level, you’ll usually need a bachelor’s degree in a behavioral science or allied mental health field, along with about 4,000 hours of supervised experience including practicum hours and 315 hours of approved coursework.
These tiers determine what you can do independently and who you can supervise. At lower tiers, you’ll practice under the direction of a more senior clinician. Higher tiers open the door to greater clinical autonomy and supervisory responsibilities.
How It Differs From Licensed Credentials
The CADC is a certification, not a license, and that distinction matters. In many states, a separate credential called the LCADC (Licensed Clinical Alcohol and Drug Counselor) or LADC (Licensed Alcohol and Drug Counselor) exists alongside or above the CADC. The key differences come down to education, independence, and diagnostic authority.
An LCADC requires a master’s degree in a related field. The most significant practical difference: an LCADC can practice independently without supervision, while a CADC must work under an approved supervisor. Both can conduct assessments, but only the licensed clinical credential allows you to make formal diagnoses. LCADCs can also supervise CADCs and counselor interns, a role the CADC cannot fill. If you’re planning a long-term career in addiction counseling, the CADC is often the starting credential, with licensure as the next step.
Requirements to Earn a CADC
Requirements differ by state, but the general framework includes three components: education hours, supervised work experience, and a written exam.
On the education side, many states require around 300 hours of coursework covering the core functions of addiction counseling. These hours must span specific topic areas, including at least 6 hours each in professional ethics, telehealth counseling, HIV/AIDS or Hepatitis C education, and trauma-informed care for substance use disorders. Some states require a bachelor’s degree for higher tiers, while others allow candidates with a high school diploma or GED to pursue entry-level certification with additional supervised hours.
Supervised clinical experience requirements are substantial. Depending on your education level and the tier you’re pursuing, expect anywhere from 4,000 to 6,000 hours of direct work experience under a qualified supervisor. That translates to roughly two to three years of full-time work in a treatment setting.
The Certification Exam
Most states use the ADC exam developed by the International Certification and Reciprocity Consortium (IC&RC). It’s a 150-question test, with 125 scored items and 25 unscored pretest questions mixed in (you won’t know which are which). Scores range from 200 to 800, and you need a 500 to pass.
The exam covers four domains:
- Treatment, counseling, and referral (30% of the exam): the largest section, focused on evidence-based therapeutic approaches
- Scientific principles of substance use and co-occurring disorders (25%): how addiction works biologically and psychologically, plus common co-occurring mental health conditions
- Professional, ethical, and legal responsibilities (25%): boundaries, confidentiality, documentation standards
- Screening and assessment (20%): identifying substance use disorders and determining appropriate levels of care
Keeping Your Certification Active
A CADC isn’t a one-time achievement. Most states require recertification every two years, which involves completing continuing education units (CEUs). The exact number of required hours varies by state and certification level, though there are typically limits on how many hours you can earn through home study (in Illinois, for instance, the cap is 15 hours per two-year cycle). The rest must come from live workshops, conferences, or approved training programs. Your credential must remain current and valid at all times. If it lapses, you’ll need to go through a recertification process before you can practice again.
Transferring Your CADC to Another State
Because each state has its own certifying board, moving to a new state means transferring your credential through a process called reciprocity. The IC&RC coordinates this between its member boards, but it’s not automatic. You’ll contact the board in your new state to learn their specific entry requirements, then file a reciprocity application through your current board. IC&RC verifies and forwards your credentials, and the receiving board follows up within 10 business days.
A few things to know: not all certification levels are eligible for reciprocity, and your credential must be current with at least 60 days of validity remaining when you apply. Some states may have additional requirements beyond what your original state required. The IC&RC also offers international certificates, such as the Internationally Certified Alcohol and Drug Counselor (ICADC), for professionals who want to work outside the U.S. These are tied to your existing state credential rather than being standalone certificates.
