What Does CADC-II Stand For?

What "CADC-II" Actually Stands For

CADC-II stands for Certified Alcohol and Drug Counselor II. Each part of that name describes a specific idea, and understanding them helps explain why the credential is structured the way it is:

• Certified - the title is awarded after meeting education, supervised experience, and examination standards, not simply after completing a training course.
• Alcohol and Drug - the scope covers substance use disorders broadly, including co-occurring mental health conditions that show up alongside addiction.
• Counselor - the role is clinical and relational, not administrative; the exam tests screening, treatment planning, and counseling skills, not just paperwork.
• II - this signals a mid-tier level on a multi-tier career ladder used by CCAPP Credentialing, distinguishing this credential from entry-level and advanced designations that share similar names.

If you're just getting oriented, the companion piece What Is CADC-II? covers the practical day-to-day of the role, while CADC-II Meaning digs deeper into how the title is used across California's addiction treatment workforce.

Who Issues the CADC-II Credential

The Certified Alcohol and Drug Counselor II credential is issued by CCAPP Credentialing, the credentialing arm of the California Consortium of Addiction Programs and Professionals. Rather than writing its own proprietary exam, CCAPP Credentialing uses the IC&RC Alcohol & Drug Counselor (ADC) examination as the testing component for CADC-II applicants. The exam itself is delivered through Prometric, using ISO-Quality Testing (IQT) as the administration partner, in a closed-book, computer-based format.

This two-organization structure - CCAPP Credentialing handling eligibility and certification, IC&RC/Prometric handling the exam - is worth understanding before you register, because fees, scheduling, and identification requirements come from different sources depending on which step you're on.

Where CADC-II Fits on the SUD Career Ladder

CCAPP Credentialing structures its substance use disorder credentials as a ladder, with CADC-II sitting in the middle tier between entry-level counselor designations and higher advanced certifications. The "II" in the name reflects the additional supervised experience and education expected at this rung compared to a first-tier credential.

Exam Format: What the Letters Translate Into on Test Day

Once you understand what CADC-II stands for, the practical question becomes: what does the exam actually look like? The IC&RC ADC exam used for CADC-II certification is:

• 150 multiple-choice questions total - 125 scored items plus 25 unscored pretest items mixed in without being identified.
• Three hours in length, administered as closed-book, computer-based testing at a Prometric/IQT test center.
• Scored on a 200-800 scale, with a passing score of 500 - not a percentage-correct threshold. For a deeper explanation of how that scaled score works, see CADC-II Passing Score 2026: Exactly What You Need to Pass.

You'll need approved government identification and your admission letter to be let into the test center, so administrative readiness matters just as much as content knowledge. If you're weighing how demanding this actually is relative to other certifications, How Hard Is the CADC-II Exam?

The Four Domains Behind the Name

The exam blueprint (effective November 2022) is organized into four content domains. Because 125 questions are scored, each domain's percentage tells you roughly how many questions to expect from that area.

Fees and Registration Mechanics

The letters "CADC-II" also carry a set of concrete costs behind them. The exam fee is $174 for CCAPP members or $338 for non-members, and a separate application-review fee applies on top of that - $165 for members or $310 for non-members. Combined, that puts the exam-plus-review total at $339 for members or $648 for non-members, before accounting for training coursework and other preparation expenses.

Once certified, renewal happens every two years and requires 50 continuing-education hours, including nine hours specifically in ethics/confidentiality, along with a renewal fee of $150 (members) or $400 (non-members).

Prerequisites Behind the Credential

Because CADC-II sits mid-ladder, its prerequisites are more substantial than an entry-level designation:

• 315 hours of approved alcohol/drug education coursework
• A 255-hour supervised practicum completed as part of that education
• 6,000 supervised experience hours total, which include the practicum hours
• Required verification paperwork and signed ethics commitments submitted with your application

These requirements exist because the "Counselor" in the name reflects real clinical responsibility - you're expected to have logged substantial supervised practice before CCAPP Credentialing will approve you to sit for the IC&RC ADC exam. CADC-II Training covers how education providers structure coursework to satisfy the 315-hour requirement.

Who Hires Someone With the CADC-II Title

Once certified, the CADC-II title is recognized across California's licensed and certified substance use disorder treatment settings - residential treatment programs, outpatient counseling centers, detox facilities, and county-funded behavioral health programs commonly staff positions that specifically require this credential. Employers value it because it signals both classroom education and thousands of hours of supervised, hands-on counseling experience, not just a certificate of completion.

Turning the Domain Breakdown Into a Study Plan

Rather than studying addiction counseling material generically, allocate review time proportional to domain weight. Since Domain 3 (Evidence-Based Treatment, Counseling, and Referral) carries 30% of scored questions, it deserves the largest single block of your preparation time - followed roughly equally by Domains 1 and 4 at 25% each, then Domain 2 at 20%.
