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.
PMI-ACP vs PMP: key differences
Use this table as a quick comparison lens. It highlights what each exam tends to reward in scenario-based questions and what to emphasize during mock practice.
| PMI-ACP emphasis | PMP emphasis |
|---|---|
| Agile mindset and adaptive planning decisions | Broader project leadership and delivery decisions |
| Team collaboration, facilitation, and feedback loops | Stakeholder constraints, governance, and integrated trade-offs |
| Iterative delivery and learning from inspection/adaptation | Planning across uncertainty with structured approaches |
| Role clarity in Agile contexts and servant leadership behaviors | Role responsibilities across broader project environments |
| Scenario logic framed around Agile values and principles | Scenario logic framed around project outcomes and constraints |
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.
