PMP vs PMI-ACP: which PMI certification?

Choose PMP if you lead projects and want the broad project management credential employers ask for by name; choose PMI-ACP if you work on agile teams and want a credential about agile practice itself. Both come from PMI, and they overlap more than they used to: the current PMP outline puts agile and hybrid scenarios at the centre of the exam. The difference is scope. PMP tests how a project manager runs a project with whatever approach fits, including predictive planning, while PMI-ACP goes deeper on agile mindset, leadership, product and delivery across several frameworks. Neither is a prerequisite for the other, and an active PMP counts towards the PMI-ACP experience requirement.

The two exams at a glance

How the two exams differ

The PMP exam is organised around three domains, People, Process and Business Environment, and asks what a project manager should do next in a project situation. Under the July 2026 outline most of those situations are agile or hybrid, but the role in the question is always the person accountable for the project, and the answers weigh scope, schedule, cost, risk, governance and the organisation around the project.

The PMI-ACP exam is organised around four domains, Mindset, Leadership, Product and Delivery, and asks how an agile practitioner should act: how to coach a team, prioritise a backlog, deliver value in small increments and improve the process. It goes further into agile values, servant leadership and specific practices than the PMP does, and it does not test predictive planning in depth.

Eligibility: what you need before you apply

Both certifications need experience and formal education before PMI will accept an application, and PMI audits a share of applications. PMP needs documented experience leading projects, with the length depending on your education, plus 35 contact hours of project management education. PMI-ACP needs agile experience plus at least 21 hours of formal training in agile practices; an active PMP counts in place of the experience.

PMI revises these terms from time to time, and books and practice exams do not count towards the training hours for either, so check the current requirements on pmi.org before you plan around them.

Which to take first

Take the one that matches your job now. A project manager on a mix of project types gains more from PMP first, and can add PMI-ACP later with the experience requirement already covered by the active PMP. Someone on an agile team who does not manage projects gains more from PMI-ACP, and may never need the PMP.

If you are deciding between them for a career move rather than your current role, look at the adverts for the roles you want. Project and programme manager adverts tend to ask for PMP; agile delivery, coaching and Scrum Master adverts are more likely to name an agile credential, and often a Scrum one rather than PMI-ACP.

How much does preparation overlap?

More than it did before PMI moved the PMP towards agile and hybrid work. Agile values, servant leadership, backlog management, iterative delivery and team facilitation appear on both exams, and studying one gives you a head start on that part of the other.

What does not carry over from PMI-ACP to PMP is the predictive and business side: planning and controlling scope, schedule and cost, governance, compliance and the wider business environment. Going the other way, the PMP will not cover agile practices in the depth PMI-ACP expects.
