The PMP and PMI-ACP both come from PMI, so this is not a contest between rival bodies. It is a question of breadth versus agile depth - and how you actually work. Here is the detailed comparison, beyond the table above.
The core difference
The PMP is PMI’s flagship, broad project-management credential. The current exam covers predictive, agile and hybrid approaches across three domains - People (42%), Process (50%) and Business Environment (8%) - with roughly half the content reflecting agile and hybrid ways of working. It signals that you can lead delivery across methods, not just one.
The PMI-ACP is the agile specialist. Rather than testing a single method, it spans agile approaches - Scrum, Kanban, Lean, XP and more - so it suits practitioners who move across frameworks. PMI refreshed it with the November 2024 Examination Content Outline, restructuring it into four domains: Mindset (28%), Leadership (25%), Product (19%) and Delivery (28%).
So the PMP is broad with substantial agile content; the PMI-ACP goes deeper into agile across frameworks but is narrower in overall scope.
Cost compared
The two are close in price, with the PMP slightly higher:
- PMP: US$405 (PMI member) or US$555 (non-member), plus the 35 hours of required education. Renewal is 60 PDUs every three years plus a renewal fee.
- PMI-ACP: US$435 (member) or US$495 (non-member), plus the 21 contact hours of agile training required to qualify. Renewal is lighter - 30 PDUs over three years.
PMI membership lowers the exam fee for both. Confirm current pricing with PMI, since the PMI-ACP program was recently updated and fees change.
Difficulty and time
Both require real experience, but they are different shapes:
- PMP: a 180-question scenario exam in 230 minutes, with stricter eligibility (a degree and documented project-leadership months that PMI may audit). It tests situational judgement across predictive, agile and hybrid work. Most candidates study two to four months. It is generally considered the harder, broader exam.
- PMI-ACP: a 120-question exam (100 scored, 20 unscored) in 180 minutes. Eligibility is lighter - a secondary degree, agile team experience, and 21 training hours - but it still assumes genuine agile practice across frameworks rather than memorising one method. Plan for roughly two to three months part-time with that experience behind you.
Neither publishes a fixed pass mark. The PMP is the heavier lift on eligibility and breadth; the PMI-ACP is narrower but still rewards real agile understanding.
Recognition and career value
This is often the deciding factor:
- PMP is the most widely recognised PM credential, frequently listed as required or preferred for project manager, program manager and delivery roles, and associated with a salary premium - especially in North America. Its weight comes partly from the experience gate behind it.
- PMI-ACP is a recognised, method-neutral agile credential. It carries real value for practitioners who genuinely work across agile frameworks, but it is more of a specialist signal than a general-purpose hiring requirement. For a single-framework Scrum role, a Scrum-specific certification such as PSM is often more targeted.
You see PMP across general PM postings; you see PMI-ACP where method-agnostic agile depth is the point.
How to decide
Answer one question: how do you work, and what role are you targeting?
- You lead projects generally, across predictive, agile and hybrid approaches → PMP. It is the higher-value, more widely recognised credential and already includes substantial agile content.
- Your work is specifically agile, across more than one framework → PMI-ACP. It goes deeper into agile practice than the PMP does.
- You work in a single framework (pure Scrum) → neither may be ideal; a Scrum-specific exam like PSM is more focused.
Some people hold both, with the PMP as the anchor and the PMI-ACP demonstrating agile depth on top. If you do sequence them, the PMP is usually the stronger foundation to earn first.
