Click Start Test above to launch a full-length CADC practice test weighted like the real IC&RC ADC exam, or drill a single domain — Scientific Principles, Screening and Assessment, Treatment, Counseling and Referral, or Professional, Ethical, and Legal Responsibilities. Every question includes a clear explanation so you learn the reasoning, not just the answer.

The Certified Alcohol and Drug Counselor (CADC) credential is awarded by IC&RC member boards and earned by passing the IC&RC Alcohol and Drug Counselor (ADC) examination.

The ADC exam is a 150-question, 3-hour, multiple-choice test that measures the core competencies entry-to-mid-level counselors need to assess, counsel, and refer people affected by substance use and co-occurring disorders.[1]

Of the 150 questions, 125 are scored and 25 are unscored pretest items, and scores are reported on a 200–800 scale with 500 required to pass. Our practice questions mirror the official four-domain blueprint and weighting so you can train the way the real exam is built.

Note: “CADC” is a board-issued credential name used by many state and member boards (the underlying national exam is the IC&RC ADC); some states instead use the NAADAC NCAC exam, so always confirm which exam your certifying board requires.[5]

To reinforce each domain, pair these with our free study guide, flashcards.

What Is on the CADC (ADC) Exam?

The CADC (IC&RC ADC) exam covers four content domains: (I) Scientific Principles of Substance Use and Co-Occurring Disorders (25%), (II) Evidence-Based Screening and Assessment (20%), (III) Evidence-Based Treatment, Counseling, and Referral (30%), and (IV) Professional, Ethical, and Legal Responsibilities (25%).[1]

Domain III (Treatment, Counseling, and Referral) carries the most weight at 30%, so prioritize it in your study plan, but every domain appears on every form. The practice drills below are organized by these official domains so you can target the areas that count most:

Practice Questions by Domain

Use Start Test for a full weighted ADC simulation, or open the hub and pick a single domain to drill your weak area. After each full exam, your results show a per-domain breakdown so you know exactly where to focus — most candidates need the most reps on treatment and counseling methods and on screening and assessment tools.

What Are the Requirements for CADC Certification?

CADC eligibility is set by each IC&RC member board — not by IC&RC itself — and varies by state and credential level.[3] Typical requirements include:

  • Education: a high school diploma/GED (some boards require an associate or bachelor’s degree)
  • SUD coursework: board-approved substance use disorder education, commonly ~150–300 hours
  • Work experience: supervised experience, often 2,000–6,000 hours depending on state and level
  • Practicum: a block of supervised practicum hours across the IC&RC performance domains

Always confirm exact education, experience, and supervision requirements with your specific certifying board before applying.

How Do You Register for the CADC Exam?

You register for the CADC (ADC) exam through your state or member IC&RC certifying board, which verifies your education and experience and authorizes you to sit for the exam.[3]

After authorization you register and schedule the computer-based exam (delivered via the testing vendor’s network of testing centers and, where offered, online proctoring). Exam fees vary by board but are commonly around $200–$275. Bring an approved government-issued photo ID on test day.

What Is the Passing Score for the CADC Exam?

The passing score for the CADC (ADC) exam is a scaled score of 500 on a 200-to-800 range, based only on the 125 scored questions.[1] The 25 pretest questions do not affect your score. Scaled scoring adjusts for slight differences in form difficulty so a passing standard means the same competency level across versions.

Candidates typically receive a pass/fail result with a scaled score; a diagnostic breakdown by domain is usually provided to those who do not pass.

How Hard Is the CADC? (Pass Rate)

The CADC (ADC) first-attempt pass rate is commonly cited in roughly the 60–75%range, though IC&RC does not publish a single official pass rate and results vary by board and candidate preparation.[4] The exam is passable but rewards focused, blueprint-aligned study rather than general counseling experience alone.

The ADC is a moderately challenging professional credentialing exam. The content is broad, spanning pharmacology and the neuroscience of addiction, screening and assessment tools (such as ASAM Criteria and biopsychosocial assessment), evidence-based counseling methods (like motivational interviewing and CBT), and ethics and confidentiality law (including 42 CFR Part 2). Many questions are application- and scenario-based rather than simple recall, so candidates who drill realistic questions and review the four-domain blueprint tend to do best.

What to Expect on Exam Day

Arrive at your testing center at least 15 minutes early to check in — bring a valid, unexpired government-issued photo ID whose name matches your exam authorization.[1]You’ll store phones and personal items before entering; no outside notes are allowed.

A short tutorial precedes the exam, then you have 3 hours to answer 150 multiple-choice questions. If you test via online proctoring, expect a similar room scan and ID check. Your certifying board processes the results, typically reporting a pass/fail outcome with a scaled score.

Having simulated the full timing with practice tests makes that clock feel routine.

How to Use This CADC Practice Test

  • Recreate exam conditions. Take the full test timed, with no notes.[5]
  • Diagnose, then drill. Use a full ADC simulation to find weak domains, then drill them.
  • Prioritize Domain III. Treatment, Counseling, and Referral is the biggest score-mover at 30%.
  • Learn the why. Read every explanation — understanding beats memorizing.
  • Answer everything. There’s no guessing penalty, so never leave a question blank.

Why Get CADC Certified?
