PMI-ACP covers agile broadly across many frameworks; PSM goes deep on Scrum specifically. One needs experience and PMI fees, the other has no prerequisite. Here is how to choose.
Table of Contents
PMI-ACP and PSM are the two agile certifications people most often weigh, and they take opposite approaches. PMI-ACP covers agile broadly — Scrum, Kanban, Lean, XP and more — and requires documented experience. PSM goes deep on Scrum specifically, has no prerequisite, and never expires. The right one depends on your role and how much you want to invest.
This comparison breaks down scope, cost, and difficulty.

Which should you choose?
Pick by your environment and whether you can clear PMI's experience bar.
Choose PMI-ACP if...
- Your teams use multiple agile frameworks, not just Scrum
- You already have agile experience to document
- You are a PMI member or hold PMP and want to add agile breadth
- You want a credential recognised across the PMI ecosystem
Choose PSM I if...
- Your organisation runs Scrum specifically
- You want a respected agile cert with no prerequisite
- You prefer a cheaper, faster, never-expiring credential
- You are a Scrum Master or entering agile for the first time
🏆 The verdict
Choose PSM I if you work in Scrum or are starting out — it is cheaper ($200), has no prerequisite, never expires, and is highly respected for Scrum roles. Choose PMI-ACP if your teams span multiple agile frameworks and you can document the required experience, especially if you already hold PMP and want to broaden into agile. For most newcomers, PSM I is the faster, lower-risk entry point.
Broad agile vs deep Scrum
The core trade-off is breadth versus depth. PMI-ACP tests agile across many frameworks — useful if your teams mix Scrum, Kanban, and Lean. PSM I goes deep on the Scrum framework and the Scrum Guide specifically. If your world is Scrum, the focused credential is more relevant; if you operate across agile methods, PMI-ACP's breadth fits better.
Cost and prerequisites
PSM I has no prerequisite and costs $200, with an 85% passing bar that rewards genuinely knowing the Scrum Guide. PMI-ACP costs more, requires documented agile experience plus training hours, and renews via PDUs every three years. For accessibility, PSM I wins; for PMI-ecosystem alignment, PMI-ACP fits. See our project management roadmap for where each sits.
Should you get both?
They complement each other: PSM I proves Scrum depth, PMI-ACP proves agile breadth. A common strong combination is PMP plus PSM I for a project manager moving into agile delivery. Adding PMI-ACP later signals multi-framework fluency. Sequence by your immediate role.
Frequently asked questions
Is PMI-ACP or PSM better?
It depends on your environment. PSM I is better if you work in Scrum or are starting out — it is cheaper, has no prerequisite, and never expires. PMI-ACP is better if your teams use multiple agile frameworks and you can document experience.
Which agile certification is easier to get?
PSM I is more accessible: $200, no prerequisite, and an hour-long exam. PMI-ACP requires documented agile experience and training hours, costs more, and is broader in scope.
Does PSM expire?
No. Scrum.org's PSM I never expires. PMI-ACP, by contrast, requires renewal through professional development units (PDUs) every three years.
Should I get PMI-ACP if I already have PMP?
It can be a good add-on if you want agile breadth within the PMI ecosystem, since you likely meet the experience requirement. But if your teams run Scrum specifically, PSM I may be the more relevant and cheaper choice.
Which agile certification pays more?
Pay is comparable and driven mostly by role and experience. Both sit roughly in the $90k-$130k range; the certificate supports rather than sets the salary.
