Here is a strange sentence that is completely true in 2026.
The standards you are expected to practice are not necessarily the standards your ICF exam is testing.
The current ICF Core Competencies were introduced in 2025. The current Code of Ethics took effect April 1, 2025. Coaches should know them and work from them.
The ACC Exam still points candidates to the 2019 Core Competencies and the 2020 Code of Ethics. The current ICF Credentialing Exam for PCC and MCC candidates does too.
So candidates ask the obvious question. If I study only the 2025 documents, could I still pass an exam written from the earlier versions?
Probably.
That answer is more reassuring than it sounds and less useful than candidates want it to be.
The 2025 standards are an evolution, not a new philosophy of coaching. Most judgment transfers. But “these documents mostly agree” is not the same as “these documents are interchangeable.”
First, identify the exam you are taking
The version problem changes with your credential and test date.
| Exam | Tested standards | What to use as your base |
|---|---|---|
| ACC Exam | 2019 Competencies and 2020 Ethics Code | 2019 and 2020 |
| Current PCC/MCC Credentialing Exam | 2019 Competencies and 2020 Ethics Code | 2019 and 2020 |
| New PCC-MCC Exam, available November 10, 2026 | Most recent Competencies and Ethics Code | 2025 and 2025 |
During the transition from November 10, 2026 through March 31, 2027, PCC and MCC candidates can choose either written exam. Test or retest on or after April 1, 2027 and you take the new PCC-MCC Exam. I break that decision down in Two PCC Exams, Two Rulebooks: Which ICF Exam Should You Take?.
ICF is unusually clear about the source split. Its ACC Exam guidance and current Credentialing Exam page name the earlier documents. Its guide to the new PCC-MCC Exam says the new test incorporates the latest updates.
Do not choose your study source by publication date. Choose it by exam.
The competencies changed less than the year suggests
“2019 versus 2025” sounds like six years of replacement. That is not what happened.
The eight overarching competencies remain the same. The four domains remain Foundation, Co-Creating the Relationship, Communicating Effectively, and Cultivating Learning and Growth.
ICF says the update added five subcompetencies, revised 11 existing ones, refined the competency definition, and introduced a glossary. Its official comparison is designed as a bridge between the two versions.
That means a candidate who understands the 2025 model still knows agreements, trust and safety, presence, listening, awareness, growth, ethics, and coaching mindset. Client agency and partnership did not become optional.
What shifted is the resolution. New and revised subcompetencies make some behaviors and distinctions more explicit. A candidate can understand the same broad competency while missing the particular wording or emphasis used by the exam writer.
That matters more on a direct knowledge question than it does in an obvious coaching scenario. If an item asks you to distinguish two closely related statements, “I understand the general idea” may not be enough.
The Ethics Code looks more different than it behaves
The 2025 Code changed visibly.
It was reorganized and renumbered. Core Values and Ethical Principles moved into the Code itself. A new section addresses commitments across the wider ICF ecosystem. Some 2020 standards moved, two were combined, and others were omitted. An appendix now defines key terms.
Two genuinely new standards deserve attention. One explicitly addresses ethical and legal obligations when using technology systems, databases, platforms, software, and artificial intelligence. Another requires disclosure when an ICF professional is acting in a different capacity, such as mentor, therapist, HR specialist, or assessor.
Those are real additions. They do not reverse the earlier Code.
ICF describes the essence of the 2025 Code as largely unchanged in its overview of the revisions. Confidentiality, agreements, conflicts of interest, truthful representation, professional boundaries, and responsibility to clients remain central.
So the likely exam answer survives most version changes. What changes is how directly the source names the issue.
One item through both rulebooks
This is an original CoachPrep scenario. It is not an official or recalled ICF item.
A coach wants to use an AI meeting assistant to summarize coaching sessions and suggest possible follow-up questions. The coaching agreement does not address recording, AI tools, data retention, or third-party processing. The provider retains uploaded material to improve its service. The coach plans to remove the client's name before uploading a session transcript.
Four possible responses:
A. Upload the transcript because removing the client's name makes the information anonymous.
B. Ask the client at the next session what insights they would like to carry forward.
C. Pause the upload, review the coach's ethical and legal obligations and the provider's data practices, and establish an appropriate agreement with the client before using the tool.
D. Upload the transcript first and tell the client about the tool if its summary proves useful.
The 2020 answer is C
The 2020 Code did not need to say “generative AI” for confidentiality, records, agreements, and applicable law to matter. Removing a name does not remove every identifying detail or establish agreement to third-party processing.
B sounds like coaching and may be a good session question. It leaves the technology decision unresolved. A treats de-identification as permission. D makes disclosure conditional on whether the coach likes the output.
C addresses the obligations before the tool touches client information.
The 2025 answer is also C
The new Code makes the technology layer explicit. A candidate studying 2025 may spot the issue faster because AI, software, databases, and technology-assisted systems are named directly.
The correct action did not suddenly become ethical in 2025. The new language made an existing responsibility harder to overlook and expanded how clearly coaches are expected to think about the systems carrying out their work.
This is what most of the version difference feels like on an applied item. The newer document changes visibility and emphasis more often than it changes the final answer.
Where studying only 2025 creates risk
If the principles transfer, why not ignore the old documents?
Because the exam does not score philosophical compatibility. It scores your response to items written and validated against a defined source.
Three risks remain.
Exact language. A knowledge item can distinguish between statements that both sound broadly consistent with coaching. The source version controls which one the exam recognizes.
Added obligations. The 2025 Code names technology and other professional roles more explicitly. A newer formulation may not match an item's older structure or emphasis.
False confidence. Familiarity with the current standards can hide a gap. You recognize the topic and assume you know how the tested document frames it.
You do not need to memorize two Codes line by line. Refusing to read the designated source creates risk without buying you anything.
ICF's own answer is “mostly transferable”
ICF tells candidates preparing for the new PCC-MCC Exam that no major change in preparation is necessary. It says existing materials remain valuable because the competencies and ethical standards have not fundamentally changed.
That statement runs in both directions.
If older preparation remains useful for a new exam based on 2025, newer preparation will carry substantial value into an older exam. That second sentence is my inference, not an ICF promise. It follows from the same continuity.
Substantial value is not complete alignment.
That is the line candidates need.
Study one system and map the difference
Do not build two independent libraries in your head.
If you are taking the ACC Exam or current Credentialing Exam: use the 2019 Competencies and 2020 Code as your tested foundation. Then review the official comparison documents so you know what current practice added or clarified.
If you are taking the new PCC-MCC Exam: study the 2025 standards directly. Keep using strong older scenario materials, but check their rationales against the updated language.
In either case, create a one-page delta sheet with three columns:
| Earlier version | 2025 change | Could this change an exam decision? |
|---|---|---|
| Existing principle or standard | Added, revised, moved, or clarified language | Yes, no, or only the rationale |
Identify where a version difference might affect what you notice, the language you recognize, or which obligation comes first.
Then practice mixed items. When you review one, ask two questions:
- Would both versions lead me to the same action?
- If yes, does the newer version change why I recognized it?
That is more useful than pretending the documents are identical or treating them as competing systems.
The practical answer
Could you study only the 2025 Competencies and Ethics Code and pass an exam based on 2019 and 2020?
Yes, you probably could.
Most of the framework remains intact. Most ethical judgment transfers. ICF itself says the standards did not fundamentally change.
Should you deliberately prepare that way when ICF has told you which documents the exam tests?
No.
Study the source your exam was built from. Use the 2025 standards to practice now. Map the differences once instead of carrying two complete rulebooks.
The goal is not to choose between passing the exam and being current as a coach.
You can do both.
