Start testHow these ADC practice tests match the real exam
The real IC&RC Alcohol and Drug Counselor (ADC) Exam has 150 questions and a 180-minute time limit. Question types: Multiple choice with three or four answer choices and one correct or best answer. 125 questions are scored and 25 are unscored pretest questions mixed in and not identified. No penalty for guessing. Each practice test here uses the same question formats, so you get used to how ADC questions are asked before test day.
The tests draw on every ADC content area, weighted like the official outline:
- Scientific Principles of Substance Use and Co-Occurring Disorders (about 25% of the exam)
- Evidence-Based Screening and Assessment (about 20% of the exam)
- Evidence-Based Treatment, Counseling, and Referral (about 30% of the exam)
- Professional, Ethical, and Legal Responsibilities (about 25% of the exam)
Use tutor mode to see the explanation after each answer, or timed mode to practise at real exam pace. Every answer comes with an explanation of why it is right and why the other options are wrong.
