Education and Training Requirements
CADC applicants must complete 225 clock hours of substance abuse counseling coursework. The 2025 ICB Counselor Model breaks those hours down as follows: 100 hours in AOD-specific content (including 15 hours on treatment services for women and/or their families and 15 hours on treatment services for adolescents and/or their families), 6 hours in professional ethics and responsibility, 10 hours in race and equity, and 109 hours in the four performance domains. The current performance domains are: Scientific Principles of Substance Use and Co-Occurring Disorders; Evidence-Based Screening and Assessment; Evidence-Based Treatment, Counseling, and Referral; and Professional, Ethical, and Legal Responsibilities.
College or university courses can count toward these hours. One semester credit hour equals 15 clock hours, so a 3-credit course covers 45 clock hours. ICB approves a number of alcohol and other drug counselor training programs in Illinois, including programs at community colleges and organizations such as the Haymarket Center in Chicago. Check the ICB website for a current list of approved programs.
Work Experience Requirements
As of July 1, 2025, new CADC applicants in Illinois need 2,000 hours of supervised work experience in the alcohol and drug addiction field. ICB defines qualified work experience as paid, supervised work in a position where at least 51 percent of the applicant’s time is spent providing direct, primary alcohol and other drug counseling. Volunteer work and unpaid internships do not qualify. At least 150 hours must be supervised practical experience across the 12 core skill areas, with no fewer than 10 hours in any single area.
Work experience must have been earned within the past four years prior to application. The previous tiered system, which allowed degree holders to substitute education for a portion of work hours, was discontinued effective July 1, 2025. All new applicants are now subject to the same 2,000-hour requirement regardless of degree level.
Application and Exam
Illinois moved to an online application process through Certemy. Applications are no longer accepted by mail. The $100 application fee is submitted through the platform. The application flows through four phases; each phase is reviewed within up to 30 days. Applicants have one year from the application date to complete the full process. All applicants are subject to a background screening.
Once your application is approved, you can register for the IC&RC Alcohol and Drug Counselor (ADC) exam. The exam includes 150 questions (125 scored, 25 pre-test) and has a 3-hour time limit. The exam fee is $225. An official IC&RC ADC Candidate Guide is available through the ICB website to help you prepare. After passing the exam, you’ll receive an invoice for the $170 biennial certification fee. Certificates are issued electronically through your Certemy account.
Recertification
CADC certification must be renewed every two years. Before renewing, you need to complete 40 ICB-approved clock hours of continuing education. At least 15 of those hours must cover alcohol and other drug topics. ICB recommends completing 20 CE hours per year to stay on track. Up to 15 of the 40 hours can be fulfilled through home-study or distance learning coursework. The $170 biennial fee is submitted through your Certemy portal.

Advanced Credentials
The CADC is the starting point. Illinois also recognizes three higher-level credentials through IC&RC for counselors with more experience and education. Each builds on the CADC and opens doors to supervisory, clinical, and advanced practice roles. Counselors who also pursue state licensure should review Illinois clinical counseling licensure requirements, which operate on a separate track from ICB certification.
CRADC: Certified Reciprocal Alcohol and Other Drug Counselor
The CRADC is Illinois’s reciprocal credential, recognized by participating IC&RC member jurisdictions. Reciprocity portability can vary depending on the receiving state’s laws, so confirm requirements with the destination state before applying. Applicants must hold the CRADC before applying for either the CSADC or CAADC. Contact ICB directly or download the 2025 IC&RC Counselor Model from the ICB credentialing page for current requirements.
CSADC: Certified Supervisor Alcohol and Other Drug Counselor
The CSADC adds a clinical supervision component and is designed for counselors moving into leadership or training roles within treatment programs. Applicants must hold the CRADC before applying. Download the current 2025 IC&RC Counselor Model from the ICB credentialing page for full requirements.
CAADC: Certified Advanced Alcohol and Other Drug Counselor
The CAADC is the highest credential in the Illinois system and requires a master’s degree in counseling, psychology, or a related field. It’s suited for counselors in advanced clinical roles or those seeking national recognition through IC&RC. Applicants with a CRADC may apply for the CAADC directly, without first obtaining the CSADC. Some counselors at this level also hold or pursue the Licensed Professional Counselor (LPC) credential, which carries independent practice authority in Illinois. Download the current model from the ICB credentialing page for full details.

Frequently Asked Questions
How long does it take to become a CADC in Illinois?
Timeline varies based on how quickly you can accumulate your work hours. With 2,000 required hours at a typical full-time pace in a qualifying AOD counseling role, most candidates complete the experience requirement in roughly one year. Add application processing time, exam scheduling, and the 225 education hours (which can run concurrently with work experience), and most people complete the full process within one to two years.
Did CADC requirements change in 2025?
Yes. Effective July 1, 2025, the ICB updated the CADC credentialing model. The most significant change reduced the required supervised work experience to 2,000 hours for all new applicants, replacing the previous tiered system that required 4,000 hours at baseline. The application process also moved fully online through Certemy, and the education hour requirements were updated to include new topic areas, including race and equity.
Can I get my CADC in Illinois online?
You can complete some or all of the required 225 education hours through ICB-approved training programs that offer online or distance learning delivery. You must apply through the Certemy online platform. The exam is administered in person at computer-based testing sites. Work experience must be gained in a supervised clinical or treatment setting with at least 51 percent of your time in direct AOD counseling.
What’s the difference between CADC and CRADC in Illinois?
The CADC is the entry-level certification for practitioners working in Illinois. The CRADC (Certified Reciprocal Alcohol and Other Drug Counselor) is an advanced credential recognized by other IC&RC member jurisdictions, which can make it easier to practice across state lines. The CRADC requires substantially more experience than the CADC and serves as the prerequisite for the CSADC and CAADC. Review the current 2025 IC&RC Counselor Model on the ICB website for the full CRADC requirements.
Is there financial assistance available for CADC applicants in Illinois?
Yes. ICB runs a CADC Workforce Expansion Program that accepts applications from eligible candidates. Funding availability varies. Check ilcadcworkforce.org for current program status and eligibility requirements.
