CADC-II Cheat Sheet 2026: One-Page Review of Must-Know Facts

TL;DR
  • CCAPP Credentialing issues the CADC-II using the IC&RC Alcohol & Drug Counselor (ADC) exam, delivered by Prometric/ISO-Quality Testing.
  • The exam has 150 multiple-choice questions (125 scored, 25 unscored) in a 3-hour, closed-book session.
  • Passing requires a scaled score of 500 on IC&RC's 200-800 range, not a raw percentage.
  • Evidence-Based Treatment, Counseling, and Referral is the heaviest domain at 30% of the exam.

What This Cheat Sheet Covers

This is a compressed, one-page-style reference for candidates who already understand the basics of the CADC-II and just need the hard numbers, domain weights, and mechanics in front of them before exam day. It is not a substitute for structured preparation - for that, see the full CADC-II Study Guide 2026 - but it works well as a final review sheet or a quick sanity check while you're building a study plan.

Everything below reflects the CADC-II as certified by CCAPP Credentialing (California Consortium of Addiction Programs and Professionals), which uses the IC&RC Alcohol & Drug Counselor (ADC) examination. If you're still confirming what the credential actually is before committing to a study timeline, start with What Is CADC-II? or CADC-II Requirements 2026.

Don't confuse scored and unscored items: All 150 questions look identical on screen, but only 125 count toward your result. There's no way to identify which 25 are pretest items, so treat every question with equal seriousness.

The Four Domains at a Glance

The ADC blueprint splits content into four domains. Knowing the weight of each one tells you where to spend your limited study hours. For a deeper breakdown of what each domain actually tests, see the CADC-II Exam Domains 2026 guide.

DomainWeight
Scientific Principles of Substance Use and Co-Occurring Disorders25%
Evidence-Based Screening and Assessment20%
Evidence-Based Treatment, Counseling, and Referral30%
Professional, Ethical, and Legal Responsibilities25%

Domain 1: Scientific Principles of Substance Use and Co-Occurring Disorders (25%)

Covers pharmacology, models of addiction, withdrawal presentations, and how co-occurring mental health conditions interact with substance use.

  • Neurobiology of substances of abuse and withdrawal syndromes
  • Biopsychosocial models of addiction
  • Recognizing co-occurring disorder patterns

Domain 2: Evidence-Based Screening and Assessment (20%)

Focuses on selecting and interpreting screening tools, intake procedures, and diagnostic criteria used to determine level of care.

  • Standardized screening and assessment instruments
  • Diagnostic criteria application
  • Placement and level-of-care decisions

Domain 3: Evidence-Based Treatment, Counseling, and Referral (30%)

The largest domain on the exam. It tests counseling techniques, treatment planning, case management, and referral practices grounded in evidence-based approaches.

  • Individual, group, and family counseling approaches
  • Treatment and recovery planning
  • Referral, coordination of care, and case management

Domain 4: Professional, Ethical, and Legal Responsibilities (25%)

Covers confidentiality law, documentation standards, scope of practice, and ethical obligations toward clients and the profession.

  • Confidentiality and mandated reporting
  • Documentation and record-keeping standards
  • Professional boundaries and scope of practice

Fees and Registration Mechanics

CADC-II costs come in two separate payments: an application-review fee and a testing fee. Both have member and non-member tiers.

FeeMember RateNon-Member Rate
Application review$165$310
Exam fee$174$338
Combined total$339$648

These figures cover application review and the exam itself - they do not include the 315 hours of approved education, the supervised practicum, or other training expenses. For a full cost breakdown, including how membership status affects your total outlay, read CADC-II Certification Cost 2026.

Key Takeaway

Joining CCAPP as a member before you apply can cut your combined exam and review fees roughly in half - confirm current membership pricing before you submit your application.

Eligibility Requirements Recap

You can't schedule the exam until CCAPP verifies your prerequisites. Here's the shorthand version; the full explanation lives in CADC-II Requirements 2026.

  • 315 hours of approved alcohol/drug education
  • 255-hour supervised practicum completed under an approved supervisor
  • 6,000 supervised experience hours, which include the practicum hours
  • Signed verification forms and ethics commitments submitted with your application

These aren't optional line items - they're gatekeeping requirements checked before an admission letter is ever issued.

Passing Score and Scoring Logic

The CADC-II exam does not report a percentage correct. Instead, IC&RC converts your raw score onto a scaled range of 200 to 800, and you need to reach 500 to pass. This scaling means two candidates who answer a different number of questions correctly on different exam forms can both land at exactly 500, because the scale accounts for item difficulty across forms.

Why this matters for your prep: Don't try to reverse-engineer "how many questions can I miss." The scaled score isn't a simple percentage, so focus your energy on mastering domain content rather than chasing a specific raw-score target. See CADC-II Passing Score 2026 for a deeper explanation of how the scale works.

One Week Per Domain: A Weight-Based Review Plan

If you have roughly a month before your test date, allocate study time proportional to domain weight instead of splitting evenly across four weeks. Domain 3 carries 30% of the exam, so it earns extra review days; Domain 2 carries the least weight at 20%, so it gets fewer.

Week 1

Scientific Principles of Substance Use and Co-Occurring Disorders (25%)

  • Review pharmacology and withdrawal presentations
  • Study biopsychosocial addiction models
  • Drill co-occurring disorder scenarios
Week 2

Evidence-Based Screening and Assessment (20%)

  • Practice reading and interpreting screening instruments
  • Review diagnostic criteria application
  • Work through level-of-care placement questions
Week 3

Evidence-Based Treatment, Counseling, and Referral (30%)

  • Focus extra hours here - it's the largest domain
  • Review counseling modalities and treatment planning
  • Practice case-management and referral scenarios
Week 4

Professional, Ethical, and Legal Responsibilities (25%) + Full Review

  • Study confidentiality law and documentation standards
  • Review scope-of-practice and boundary scenarios
  • Take a full-length practice run on the practice test site to simulate the 3-hour format

For candidates who want more detail on pacing and how difficult each domain tends to feel in practice, How Hard Is the CADC-II Exam? and the general CADC-II Study Guide go further than this cheat sheet can.

Renewal and Continuing Education

Passing the exam isn't the finish line - CADC-II certification renews on a two-year cycle, and lapses are avoidable if you track requirements early.

Renewal RequirementDetail
Cycle lengthEvery 2 years
Total CE hours required50 hours
Ethics/confidentiality hours required9 hours (part of the 50)
Renewal fee (member)$150
Renewal fee (non-member)$400

Building a habit of logging CE hours right after you pass - rather than scrambling in month 23 - keeps the renewal fee the only surprise you'll face.

Test-Day Checklist

The exam is closed-book and computer-based, delivered at a Prometric testing center through ISO-Quality Testing (IQT). A few mechanics catch candidates off guard if they haven't planned ahead:

  • Bring approved government-issued identification - check the exact acceptable ID formats before your appointment.
  • Bring your admission letter; you won't be seated without it.
  • Expect no reference materials, notes, or personal items at your workstation.
  • Plan your pacing across all 150 questions within the 3-hour window, since scored and unscored items aren't distinguishable.

Before booking, confirm current testing windows and blackout periods in CADC-II Exam Dates 2026, since scheduling availability through Prometric can shift by region.

Key Takeaway

Run at least one full-length timed practice exam on a CADC-II practice test platform under real 3-hour conditions so the pacing feels familiar, not improvised, on test day.
