How is the PMI-ACP exam different from the PMP exam?


This page compares PMI-ACP and PMP by what the scenarios test, how decisions are framed, and how to adapt mock-exam practice and readiness checks.

Direct answer

PMI-ACP differs from PMP primarily in what it prioritizes: PMI-ACP scenarios emphasize Agile values, team collaboration, and adaptive planning choices, while PMP scenarios emphasize broader project leadership and delivery decisions across multiple delivery approaches.


What a mock exam is (and why it matters for comparison)

A mock exam is a timed, exam-format practice test designed to approximate the real exam so you can validate decision-making, pacing, and stability of performance under constraints.

  • For PMI-ACP: validate Agile decision rules (collaboration, feedback loops, adaptive planning)
  • For PMP: validate integrated decision-making (stakeholders, constraints, risk, trade-offs)
  • Use results as evidence across multiple attempts, not as a one-time score
  • Track pacing and late-exam accuracy to detect endurance or time-management issues

Why mocks matter for PMI-ACP vs PMP

Mocks help expose whether your decision logic matches the exam’s scenario framing. The same study content can produce different outcomes depending on how the exam expects you to prioritize values, roles, and constraints.

1) Align decision rules
Map your “best next action” logic to the exam: PMI-ACP typically rewards Agile principles and team empowerment; PMP typically rewards structured, context-aware project decisions.
2) Validate scenario pattern recognition
Use mocks to confirm you can quickly identify the scenario type (planning, collaboration, risk, stakeholder conflict) and apply the right rule under time pressure.
3) Use review as the main improvement mechanism
Review should focus on why the correct option is best and why distractors are tempting; this builds transferable decision quality for both exams.
4) Calibrate pacing
Track time-per-question and late-exam accuracy drift; pacing issues can look different between PMI-ACP and PMP depending on scenario density.

Common mistakes when comparing PMI-ACP and PMP

Comparison errors often come from assuming that a strong score in one exam’s mocks transfers directly to the other. Use exam-specific decision rules and evidence checks.

  • Using PMP-style control-oriented choices in PMI-ACP scenarios without checking Agile values
  • Treating definition recall as sufficient for PMI-ACP when scenarios require context-based judgment
  • Assuming mock difficulty equals realism without checking distractor plausibility
  • Ignoring pacing signals and focusing only on overall score
  • Over-testing (too many full mocks) without improving the review loop

Readiness signals (if/then) for each exam

Use these rules to decide whether to keep taking full mocks or shift to targeted practice. Apply them to patterns across multiple timed attempts.


Summary and practical next steps

Choose the exam lens first (Agile decision rules for PMI-ACP; broader project trade-offs for PMP), then select mocks that mirror that lens. A practical PMI-ACP planning baseline is at least 6 full timed mocks, supplemented by targeted mini-mocks for weak areas; after consistently achieving scores around or above 90%, an additional 3–5 full timed mocks are typically sufficient to confirm performance stability.
