The Alcohol and Drug Counselor (ADC) exam measures the knowledge and skills needed to provide effective substance use disorder counseling. Developed by the International Certification & Reciprocity Consortium (IC&RC), the exam covers addiction science, screening and assessment, treatment and counseling, referral, and professional, ethical, and legal responsibilities.
What Is the Alcohol and Drug Counselor Exam?
The Alcohol and Drug Counselor (ADC) examination is developed by IC&RC for professionals who provide counseling and related services to people affected by substance use disorders.
IC&RC develops the examination and establishes minimum credentialing standards. Actual certification or licensure is handled by IC&RC Member Boards and other administering boards, which may establish requirements beyond the IC&RC minimums.
Requirements vary by jurisdiction. Your state or local administering board determines whether you are eligible, what application documents you need, how much you pay, and any additional requirements for receiving the credential.
ADC Exam Format
The examination contains multiple-choice questions with three or four answer choices. Each question has one best answer.
Twenty-five questions are unscored pretest questions being evaluated for possible use on future exams. They are mixed throughout the test and are not identified.
There is no penalty for guessing. Your score is based on the scored questions you answer correctly, so answer every question even when you are unsure.

How Do I Register for the ADC Exam?
You do not apply directly to IC&RC to take the ADC exam.
1. Find your administering board.
Contact the IC&RC Member Board or other approved credentialing board serving your jurisdiction.
2. Complete its eligibility process.
Your board reviews your education, experience, supervision, and any other local requirements.
3. Receive examination approval.
Once the board determines that you are eligible, it preregisters you for the ADC examination.
4. Schedule your exam.
You receive instructions for selecting an available testing appointment through the IC&RC testing system.
How Much Does the ADC Exam Cost?
There is no single national ADC examination fee.
Exam fees are established through administering boards and can vary by state or jurisdiction. Candidates may also have separate application, certification, licensing, or administrative fees.
Check with your administering board before budgeting for the exam. A fee listed by one state, certification board, or testing website does not necessarily apply in another jurisdiction.
Where Is the ADC Exam Taken?
IC&RC examinations are delivered through computer-based testing.
Depending on your administering board, you may have one or both of the following options:
Take the exam at an approved computer-based testing location using the scheduling instructions supplied after registration.
Some administering boards permit candidates to test remotely from home using Prometric’s remote-proctoring system.
Remote testing is not available automatically. Your administering board decides whether remote proctoring is permitted for its candidates.
What Should I Bring on Test Day?
For an in-person examination, you must bring:
A valid government-issued photo ID
Your Candidate Admission Letter issued through the examination process
If you do not have the required identification or admission documentation, you may be treated as a no-show and forfeit the examination fee.
Phones, study materials, books, paper, and other unauthorized items cannot be used during the examination.
Can I Reschedule the ADC Exam?
Current IC&RC policy requires an examination to be canceled or rescheduled at least 5 days before the scheduled testing date.
Changes are made through the testing provider, and a cancellation or rescheduling fee may apply.
If you miss the exam, arrive without the required identification or admission documentation, or otherwise receive a no-show status, your exam fees can be forfeited and you may need to register and pay again through your administering board.
How Is the ADC Exam Scored?
ADC examination scores are reported on a scale from 200 to 800.
Passing score: 500. You must earn a scaled score of at least 500 to pass the ADC examination.
Your raw score is determined by the number of scored questions answered correctly. That result is then converted to the 200–800 reporting scale.
A score of 500 should not be interpreted as answering a particular percentage of the exam correctly. IC&RC uses a standard-setting process and scaled scoring so that different forms of the examination use the same passing standard.
When Will I Get My ADC Score?
You receive a preliminary computer-based testing result immediately after completing the examination.
Your official result is sent to your designated administering board for distribution. Official CBT results generally take approximately two to three weeks.
Your official report states whether you passed or failed. Candidates who do not pass receive their final scaled score and percentages of questions answered correctly in each content domain to help identify areas for additional study.
What If I Don’t Pass?
The IC&RC minimum retest waiting period is 90 days after your examination date.
An administering board may require a waiting period longer than 90 days. The minimum waiting period cannot be waived.
After four consecutive unsuccessful attempts, IC&RC requires the administering board to assign remedial action before another attempt. Some boards require remediation after three unsuccessful attempts.
How Long Does the ADC Credential Last?
IC&RC’s minimum recertification standard requires 40 hours of continuing education every two years.
Your administering board may use a different renewal interval or impose additional continuing-education, ethics, fee, or documentation requirements.
How Can I Prepare for the ADC Exam?
Use the official four-domain blueprint to organize your study time. The exam tests application as well as factual knowledge, so practice with realistic counseling scenarios rather than relying only on memorization.
