PSM I vs PSM II: which Scrum Master certification should you take first?

If you're planning to get certified as a Scrum Master through Scrum.org, you'll quickly hit a fork in the road: PSM I or PSM II. Both are called "Professional Scrum Master." Both cost money and require 85% to pass. So people assume PSM II is just "PSM I but a bit harder," take a run at it, and get surprised.

It isn't a bit harder. It's a different exam measuring a different thing. Here's how to choose.

The one-line difference

PSM I checks whether you know Scrum. PSM II checks whether you can apply it when reality gets in the way. That single distinction explains almost everything else about how the two exams feel and how you should prepare.

PSM I: do you know the framework?

PSM I is the foundation credential. Every question can, in principle, be answered by someone who truly understands the Scrum Guide (2020) — the roles, the events, the artifacts, and the theory behind them.

• Format: 80 multiple-choice questions in 60 minutes.
• Pass mark: 85% (68 of 80 correct).
• Prerequisite: none.
• Feels like: a fast, precise knowledge test. You either know that the Sprint length is fixed, or you don't.

The trap in PSM I isn't difficulty — it's speed and precision. 45 seconds per question means you can't afford to second-guess. And the questions are written to punish "workplace Scrum": if your company does something that isn't in the Scrum Guide, the exam will happily offer that as a wrong answer that feels right.

PSM II: can you apply it under pressure?

PSM II is where people who "know Scrum" get humbled. The questions drop you into a realistic, messy scenario — a team, a stakeholder, a conflict — and ask what a Scrum Master should do. Several answers are defensible. You have to pick the most effective one.

• Format: 30 questions in 90 minutes.
• Pass mark: 85% (about 26 of 30).
• Prerequisite: none officially, but PSM I knowledge is assumed throughout.
• Feels like: a judgement test. Three minutes per question, and you'll use them.

Because only a handful of wrong answers costs you the pass, PSM II is unforgiving of shaky fundamentals. You can't brute-force it by memorising — you have to reason like an experienced Scrum Master who understands why the framework is built the way it is.

So which one first?

For almost everyone, the answer is PSM I first, then PSM II — and here's the honest reasoning, not just the safe advice:

1. PSM II assumes PSM I knowledge. The scenarios only make sense if the framework is already automatic for you. Skipping PSM I means learning two things at once under exam pressure.
2. PSM I proves value fast. On a CV, PSM I already signals credibility. It's the credential most job listings actually ask for.
3. PSM II is a genuine differentiator. Fewer people hold it, so once you have PSM I, PSM II is what sets you apart in a crowded field of certified Scrum Masters.

The exception: if you're a seasoned Scrum Master who has genuinely internalised the Scrum Guide and coached real teams through conflict, you can go straight to PSM II. Just don't confuse "I've done Scrum at work" with "I know the framework cold." The exam knows the difference.

How to prepare for each

Try before you buy: our free PSM I and free PSM II questions show the real style. The single highest-leverage prep step for both exams is the same: take realistic practice exams under timed conditions until you're consistently above the pass mark. Reading the Scrum Guide builds knowledge; practice exams build the two things that actually get tested — recall speed for PSM I, and judgement for PSM II.

For PSM I, drill for precision and pace. For PSM II, drill scenario questions and, crucially, read the explanation for why the other options are worse — that reasoning is the skill being tested.
