ICF Credentialing Exams: ACC vs. PCC/MCC and How to Prepare
What ICF exam do ACC, PCC, and MCC candidates take?
ACC candidates take the 60-item, 90-minute ACC Exam. PCC and MCC candidates take the 78-item, 180-minute ICF Credentialing Exam. The ACC exam uses single-answer knowledge questions; the PCC/MCC exam uses coaching scenarios in which candidates select the best and worst actions. Both currently test the 2019 ICF Core Competencies and 2020 Code of Ethics.
The phrase ICF credentialing exam now refers to two different assessments. That distinction matters: preparing for an ACC knowledge exam as if it were the PCC/MCC situational-judgment exam wastes time, while using old Coach Knowledge Assessment (CKA) guides can teach a format ICF no longer administers.
This guide explains the current ACC and PCC/MCC formats, what each exam tests, how to prepare, and where to find ICF exam sample questions. ICF’s own exam pages remain the authority if policies change.
Key Takeaways
- ACC and PCC/MCC candidates take different exams.
- The ACC Exam has 60 knowledge-based items and 90 minutes.
- The PCC/MCC ICF Credentialing Exam has 78 scenarios and 180 minutes.
- Both exams use a 200–600 scaled score; 460 is the passing score.
- Current exam content still reflects the 2019 competencies and 2020 ethics code, even though ICF updated both standards in 2025.

ICF delivers both exams as proctored computer-based assessments through Pearson VUE, either at an approved testing center or through online proctoring where available. Read the current ICF ACC Exam page or ICF PCC/MCC exam page before scheduling.
What the ACC Exam Tests
The ACC Exam validates foundational knowledge. ICF organizes the content into three areas: ethics; the definition and boundaries of coaching; and coaching competencies, strategies, and techniques. The current weighting is 30% ethics, 30% definition and boundaries, and 40% competencies and strategies. Ten of the 60 items are unscored field-test questions, but candidates are not told which ones they are.
ACC preparation should focus on precise distinctions: coaching versus consulting, mentoring, or therapy; confidentiality and conflicts of interest; when referral is appropriate; how agreements are established; and which response best reflects the competencies. The exam asks for one correct answer, so practice identifying why each distractor is less aligned.
What the PCC and MCC Credentialing Exam Tests
The PCC/MCC exam tests application. Each item presents a coaching scenario with four actions. Candidates choose the best action and the worst action. Several options may sound plausible in ordinary professional life; the task is to identify which is most and least aligned with ICF’s coaching definition, competencies, and ethics.
The exam covers four domains: Foundation, Co-Creating the Relationship, Communicating Effectively, and Cultivating Learning and Growth. The eight competencies are distributed across those domains. Do not study this as a vocabulary test. Practice explaining what in the scenario makes one response more coach-like, ethical, client-centered, or agreement-aligned than another.
ICF introduced updated Core Competencies and a new Code of Ethics in 2025. Its current exam guidance says the ACC and PCC/MCC exams still test the 2019 Core Competencies and 2020 Code of Ethics. Know the current professional standards, but use the versions ICF names for exam preparation.
How to Prepare for the ICF Credentialing Exams
1. Confirm your exam before choosing materials
ACC candidates need single-answer knowledge practice. PCC and MCC candidates need best-and-worst scenario practice. A resource that says only “ICF exam” without naming the credential or format may be outdated.
2. Build an exam-version source set
Use the 2019 competencies, 2020 ethics code, ICF definition of coaching, and the official candidate guide for your credential. ACC candidates should also review the ACC Minimum Skills Requirements. PCC candidates can use the ICF PCC Markers to connect competency language with observable coaching behavior, while remembering that the markers are not a substitute for the exam blueprint.
3. Practice reasoning, not answer memorization
For each practice item, state the principle being tested and why the other choices fail. On a situational item, ask: What did the client ask for? What agreement exists? Is there an ethical boundary? Which response preserves client agency? On an ACC item, identify the exact standard that makes one answer correct.
4. Rehearse the actual pace
Complete timed sections rather than isolated questions only. For ACC, rehearse 30 questions per section. For PCC/MCC, rehearse 39 scenarios per section and remember that each scenario requires two selections. Use the optional break in practice so exam-day pacing feels familiar.
5. Diagnose patterns in missed questions
Sort errors by ethics, boundaries, agreements, trust and safety, presence, listening, awareness, and growth. A score alone tells you little. A pattern tells you what to revisit in your education materials and discuss with a mentor coach.
A Four-Week ICF Exam Study Plan
| Week | Focus | Output |
|---|---|---|
| 1 | Confirm exam; read the official blueprint, 2019 competencies, 2020 ethics code, and coaching definition. | A one-page map of domains, boundaries, and recurring ethical duties. |
| 2 | Work untimed questions and explain every answer. | An error log organized by competency or content area. |
| 3 | Complete timed half-exam sections and review weak patterns. | Stable pacing and a short list of concepts to revisit. |
| 4 | Run one or two full simulations; review only recurring gaps. | An exam-day plan for timing, break, online or test-center requirements, and recovery after a difficult item. |
Four weeks is a planning example, not a required minimum. Candidates who completed training recently and use the competencies in practice may need less review; candidates returning after a gap may need more. Preparation quality matters more than stretching a generic schedule to eight weeks.
Passing Scores, Results, and Retakes
Both current exams report scaled scores from 200 to 600, with 460 required to pass. Do not convert 460 into a raw percentage; scaled scores account for differences among exam forms.
ICF’s ACC Candidate Guide states that an exam retake costs $105, with a 14-day wait after the first attempt and a 30-day wait after subsequent attempts. Policies can change and credential guides may differ, so confirm the current candidate guide and your ICF account instructions before paying or scheduling.
Where to Practice ICF Exam Questions
Start with ICF’s official tutorial or sample material for your exam. Then use our ICF exam sample questions with answers to practice the PCC/MCC best-and-worst reasoning format. ACC candidates should prioritize the official ACC tutorial and single-answer knowledge questions rather than assuming every scenario bank matches their exam.
If you are still choosing an education path, Tandem’s ICF Level 1 ACC training and ICF Level 2 ACC/PCC training integrate credential requirements, coaching practice, mentor coaching, and exam readiness.
Frequently Asked Questions
Is the CKA still the ICF credentialing exam?
No. Current ICF materials distinguish the ACC Exam from the ICF Credentialing Exam used for PCC and MCC. Older articles may call a prior assessment the Coach Knowledge Assessment or CKA. Check the current ICF page for your credential instead of preparing from the old 155-question format.
How many questions are on the ICF exam?
The ACC Exam has 60 multiple-choice knowledge items. The PCC/MCC ICF Credentialing Exam has 78 situational-judgment items. Each PCC/MCC scenario requires candidates to select both the best and worst actions.
What score do I need to pass an ICF exam?
Both the ACC Exam and PCC/MCC ICF Credentialing Exam use a scaled score from 200 to 600. ICF states that 460 is required to pass.
Can I take the ICF exam online?
ICF offers computer-based testing through Pearson VUE, including testing centers and OnVUE remote proctoring where available. Online testing requires a compatible computer, webcam, stable connection, private room, and compliance with Pearson VUE’s current check-in rules.
Which competencies and ethics code should I study?
ICF’s current exam pages direct candidates to the 2019 ICF Core Competencies and 2020 Code of Ethics. The professional standards were updated in 2025, but ICF says the current ACC and PCC/MCC exam content does not yet reflect those newer versions.
Are the ACC and PCC exams the same?
No. ACC candidates take a 60-item knowledge-based exam with one correct answer per question. PCC candidates take the 78-item ICF Credentialing Exam and select the best and worst actions for each coaching scenario. MCC candidates use that same PCC/MCC exam format.
Conclusion
The most important preparation decision is choosing materials for the exam you will actually take. ACC candidates need foundational knowledge and single-answer discrimination. PCC and MCC candidates need applied judgment in realistic scenarios. Use ICF’s current blueprint, practice the correct format under time, and turn missed questions into a map of what to study next.
