CADC-II Pass Rate 2026: What the Data Shows

Why There's No Official CADC-II Pass Rate Number

If you're searching for a single published pass rate for the Certified Alcohol and Drug Counselor II credential, you'll come up empty. CCAPP Credentialing, the California Consortium of Addiction Programs and Professionals, administers this certification using the IC&RC Alcohol & Drug Counselor (ADC) examination, delivered through Prometric via ISO-Quality Testing (IQT). Neither CCAPP nor IC&RC publishes a rolling public pass-rate percentage the way some other testing bodies do.

That absence of a headline number is actually useful information in itself. Instead of chasing a statistic that doesn't exist, the smarter approach is to look at what the exam's own structure tells you about difficulty and preparation. The scoring model, question count, domain weighting, and prerequisite hours all shape how likely a candidate is to pass - and all of that is documented and verifiable, unlike an unofficial pass-rate rumor circulating in a study group.

What the Passing Score Actually Tells You

The IC&RC ADC exam used for CADC-II certification is scored on a 200-800 scaled range, with 500 required to pass. This is not a raw percentage-correct score. IC&RC uses scaled scoring specifically so that different exam forms with slightly different item difficulty can still be compared fairly across candidates and testing windows.

Practically, this means two things for anyone trying to estimate their odds:

• You cannot simply count "I got roughly 75% right" and assume that's a pass - the scale adjusts for question difficulty.
• A borderline scaled score close to 500 doesn't tell you which domain cost you points; only a domain-level review of your preparation will reveal that.

For a full breakdown of how the 500 threshold works and what it means relative to the 200-800 range, see the CADC-II Passing Score guide.

Exam Format and Question Style That Shape Outcomes

The ADC exam behind the CADC-II credential is a closed-book, computer-based test administered at Prometric testing centers. Candidates need approved identification and their admission letter to sit for the exam. The format itself is straightforward on paper but demanding in practice:

• 150 total multiple-choice questions - 125 scored and 25 unscored pretest items mixed in without identification, so every question must be treated as if it counts.
• Three-hour time limit, which averages out to roughly 70-75 seconds per question if you want a comfortable buffer for review.
• Closed-book conditions mean no reference materials, no notes, and no external resources - everything must be internalized before test day.

Because 25 of the 150 questions are unscored pretest items you can't identify, pacing discipline matters more than trying to guess which questions "count." Treat every item with equal seriousness and move on quickly from questions you're unsure of rather than burning disproportionate time on them.

The Domain Weighting That Drives Difficulty

The single most useful predictor of where a candidate's preparation will be tested hardest is the domain weighting itself. The current ADC blueprint, effective November 2022, breaks the exam into four domains:

Because Evidence-Based Treatment, Counseling, and Referral makes up nearly a third of the entire exam, it deserves proportionally more study time than the other three domains combined would suggest at first glance. Candidates who under-prepare this domain - treating it as "just counseling technique review" - are disproportionately likely to see it drag their scaled score down, since it's simply worth more raw points than any other single area.

The remaining two domains - Professional, Ethical, and Legal Responsibilities and Evidence-Based Screening and Assessment - round out the blueprint at 25% and 20% respectively. A full topic-by-topic breakdown of all four domains, including subtopics within each, is available in the CADC-II Exam Domains 2026: Complete Guide to All 4 Content Areas.

Prerequisites as a Hidden Filter on Outcomes

One reason it's hard to compare CADC-II outcomes to other certifications is that the eligibility bar to sit for the exam is already substantial. Before a candidate can even register, CCAPP requires:

• 315 hours of approved alcohol/drug education
• 255-hour supervised practicum
• 6,000 supervised experience hours, which include the practicum hours
• Required verification documentation and signed ethics commitments

This front-loaded experience requirement functions as a natural readiness filter. By the time a candidate reaches the testing center, they've typically spent years in supervised clinical practice - which means exam performance is less about last-minute cramming and more about whether that accumulated experience has been organized into exam-ready recall. For the complete eligibility breakdown, see the CADC-II Requirements 2026 guide.

Who Sits for This Exam and Why It Matters

Most candidates pursuing this credential are already working in California substance use disorder treatment settings - residential programs, outpatient clinics, county behavioral health departments, and sober living organizations that require or strongly prefer state-recognized counselor credentials. Because CCAPP Credentialing ties CADC-II directly into a broader career ladder, many candidates are counselors advancing from an entry-level credential toward CADC-II as a documented step up in scope of practice and employability.

This matters for pass-rate intuition because it means the candidate pool isn't a mix of total newcomers and veterans - it's overwhelmingly people already embedded in clinical practice, working toward a credential that employers actively look for when hiring. If you're evaluating whether pursuing the credential fits your career plans, the CADC-II Jobs overview and the CADC-II Salary Guide 2026 outline what the credential unlocks on the employment side.

Where Candidates Typically Lose Points

Without a published item-analysis report, it's not possible to state exact percentages of candidates missing specific question types. But the structure of the exam itself points to predictable friction areas:

• Ethics and legal scenario questions (Professional, Ethical, and Legal Responsibilities, 25%) often require applying a rule to a nuanced situation rather than recalling the rule itself - candidates who only memorize definitions struggle here.
• Screening and assessment tool selection (20%) tests whether candidates know which validated instrument fits which clinical scenario, not just that the instruments exist.
• Treatment and counseling questions (30%) frequently present multiple plausible-sounding answers, requiring candidates to identify the best evidence-based response rather than just an acceptable one.
• Pacing under the three-hour limit causes some candidates to rush the final block of questions, particularly within the largest domain, simply because it appears in greater volume.

Building a Study Plan Around the Data You Do Have

Since there's no public pass-rate percentage to reverse-engineer, the smartest use of preparation time is allocating study hours in rough proportion to domain weight - with extra buffer time for the domain that carries the most points.

Spacing repeated review sessions across weeks rather than cramming a single domain in one sitting tends to improve retention - but the sequencing above is deliberately weighted toward the domain worth the most exam points first, while it's freshest heading into test day. A step-by-step walkthrough of this kind of plan is available in the CADC-II Study Guide 2026: How to Pass on Your First Attempt, and you can build timed practice familiarity using the full-length simulations on the main practice test site.

The Real Cost of a Retake

Because there's no published pass rate to gauge risk against, it's worth being concrete about what a failed attempt actually costs. The exam fee alone is $174 for CCAPP members or $338 for non-members. That's separate from the application-review fee of $165 or $310. Combined, first-time candidates are already looking at $339 (member) or $648 (non-member) before training costs. A failed attempt means paying the exam fee again to reschedule - the review fee typically isn't repeated, but the exam cost is.

For the full fee structure, including renewal costs of $150 (members) or $400 (non-members) every two years with 50 continuing-education hours, see the CADC-II Certification Cost 2026: Complete Pricing Breakdown.
