Read the scenario. Name the competency. Distractors are the real, documented overlaps.
Being straight with you about the source: actual ICF exam questions are confidential and never published — no legitimate source has "past ACC exam questions" to draw from, and any site claiming to sell them isn't legitimate. These 30 are original scenarios I wrote, double-checked against the official 2019 Core Competencies framework (re-verified before building this), and built specifically around the near-miss pairs documented in your Overlap Guide — so the wrong answers are the competencies people genuinely confuse, not random ones.
Each scenario has one clearly correct competency and three plausible-sounding alternates. The explanations name exactly which word or detail in the scenario decides the answer — that's the transferable skill, not the specific question.
