Eighty questions, sixty minutes, an 85% pass mark, $200 per attempt, no course required, and a certificate that never expires. Those six facts are the Professional Scrum Master I in miniature, and they explain both why candidates choose it and why a surprising number of experienced practitioners fail it. Scrum.org — the organisation founded by Scrum co-creator Ken Schwaber — built the PSM as a pure knowledge assessment: nobody checks how you learned, only whether you can demonstrate a precise understanding of Scrum under time pressure.

That design cuts both ways. The freedom to self-study makes PSM I one of the most affordable and flexible routes to a scrum master credential. The 85% threshold — you can miss barely one question in eight — makes it unforgiving of the fuzzy, workplace-flavoured version of Scrum most people actually carry around. This guide covers the full Scrum.org scrum master track, the PSM I exam in detail, and a study sequence that gets self-studiers over that threshold.

The Scrum.org PSM levels: I, II and III

Professional Scrum Master is not one certification but a three-level track, each level assessing a different depth of mastery. All three share Scrum.org's structural traits: online, un-proctored, priced per attempt, and valid for life with no renewal fees.

PSM I — demonstrating fundamental Scrum knowledge

PSM I certifies that you understand Scrum as described in the Scrum Guide and can apply its rules and roles consistently. It costs $200 USD per attempt and is the level the rest of this guide focuses on, because it is where nearly everyone starts.

PSM II — applying Scrum in messy reality

PSM II is a $250 USD assessment of 30 questions in 90 minutes, again at an 85% pass mark. The questions are advanced and situational: less "what does the Scrum Guide say" and more "your product owner is doing X and your organisation demands Y — what does a good scrum master do?" There is no formal prerequisite, but PSM I-level knowledge is assumed, and students who complete an official Scrum.org PSM course receive a 40% discount on a PSM II attempt. When you reach this stage, the Professional Scrum Master II exam page outlines what the assessment covers.

PSM III — the distinguished tier

PSM III costs $500 USD per attempt and combines multiple-choice items with essay questions graded by human evaluators, still at an 85% bar. It is a multi-hour exam, and Scrum.org community sources consistently describe it as the hardest Scrum credential to earn, with low pass rates. Scrum.org publishes the current format details on its site; treat PSM III as a goal for practitioners with years of coaching depth rather than a near-term target.

The sensible reading of the ladder: PSM I proves you know Scrum, PSM II proves you can apply it in difficult organisational situations, PSM III proves you can articulate and defend mastery. Climb one rung at a time.

PSM certification requirements

There are none — and that is the point. Scrum.org imposes no prerequisite course, no experience minimum, and no application process for PSM I. You create a Scrum.org account, buy an attempt password, and take the assessment when ready. Training exists (Scrum.org's Professional Scrum Master course, taught by its Professional Scrum Trainers, includes a free exam attempt), but it is genuinely optional, not a soft requirement.

The practical requirement is different from the formal one: you need a rigorous, current understanding of the Scrum Guide — the 2020 edition, on which the exam is based. Reading it once is nowhere near enough, for reasons the next section makes clear.

PSM I exam format in detail

As of 2026, the PSM I assessment looks like this (confirm current details on Scrum.org before booking, as the provider updates its assessments periodically):

Questions: 80
Time limit: 60 minutes — 45 seconds per question on average
Question types: multiple choice, multiple answer, and true/false
Pass score: 85%
Delivery: online, un-proctored, taken from your own computer
Language: English (the assessment is based on the 2020 Scrum Guide)
Cost: $200 USD per attempt, the same flat price worldwide
Validity: lifetime — no expiry, no renewal fees, ever

Three features deserve unpacking.

The pass mark does most of the gatekeeping. At 85%, you can afford to get roughly 12 of 80 questions wrong. Multiple-answer questions ("choose all that apply") are typically scored as fully right or wrong, so partial knowledge earns nothing. This is why practitioners with years of real-world experience fail PSM I: their organisations' adaptations of Scrum have quietly overwritten what the framework actually defines, and a dozen "that's how we do it at work" answers is all it takes.

The clock is a genuine constraint. Eighty questions in sixty minutes leaves no slack for dwelling. The exam interface lets you bookmark questions to revisit, and disciplined candidates answer everything on a first fast pass, then spend remaining minutes on bookmarks.

Un-proctored does not mean open book in any useful sense. Nobody watches you, but 45 seconds per question means that looking answers up is a losing strategy. Candidates who plan to "just search the Scrum Guide" run out of time long before they run out of questions. Prepare as if it were closed book.

How to pass PSM I: a study sequence that works

Because there is no mandatory course, your preparation is entirely your own. Here is a prioritised sequence that reflects how the exam actually tests knowledge — deep precision on a small body of material, applied under time pressure.

1. Read the 2020 Scrum Guide — then read it again, slowly

The Scrum Guide is around a dozen pages and is the exam's foundation document. Read it once for the shape, then a second time interrogating every sentence: why is the sprint goal a commitment for the sprint backlog? Who is accountable for product backlog ordering? What exactly happens if the definition of done is an organisational standard? PSM I questions frequently hinge on precise wording — "accountable" versus "responsible", "the scrum team" versus "the developers".

2. Map your workplace deviations

Write down every place your real team departs from the Guide — who runs your daily scrum, who accepts work as done, how sprints get extended. Each deviation is a probable wrong answer waiting for you in the exam. Making the list explicit is the fastest way to stop your experience from sabotaging your score.

3. Use the Scrum Open assessment until you clear it comfortably

Scrum.org provides the free Scrum Open practice assessment on its website. It is shorter and easier than PSM I, but it teaches you the question style and flags fundamental gaps. A common self-benchmark in the Scrum.org community: when you can score at or near 100% on the Open assessment repeatedly and quickly, you are ready to study at exam depth — not yet ready to pass.

4. Drill full-length, timed practice tests

The jump from the Open assessment to the real thing is significant: more questions, harder scenarios, tighter effective time. Timed practice at full length trains the pacing — 45 seconds a question — and exposes weak domains while mistakes are still free. Analyse every wrong answer against the Scrum Guide's text rather than memorising the correct letter; the exam pool is large enough that only understanding transfers. A timed set of PSM I practice questions will show you whether you are consistently above the 85% line before you spend $200 on an attempt.

5. Close specific gaps with targeted reading

If practice results show a soft spot — scaling questions, the scrum master's stance toward the organisation, artifact commitments — go back to the relevant Scrum Guide passages and Scrum.org's suggested reading rather than rereading everything. Precision, not volume, is what the last week before the exam is for.

Are you ready? A pre-booking checklist

Book your attempt when you can honestly tick all of these:

I can name the three accountabilities, five events and three artifacts — with each artifact's commitment — without hesitation.
I can explain what the scrum master does for the product owner and the organisation, not just the developers.
I score above 85% on full-length timed practice tests consistently, not once.
I finish 80-question practice sets with time to spare for bookmarked questions.
I know where my workplace deviates from the Scrum Guide, and I answer from the Guide, not from habit.
I have re-read the Scrum Guide within the last week.

If any box stays unticked, the fix costs hours; a failed attempt costs $200 and another sitting.

Taking the exam: what the day looks like

You purchase an attempt password from Scrum.org, which does not expire until used, and start the assessment whenever you choose — no scheduling, no proctor, no test centre. Sit it somewhere quiet with a stable connection, at your mentally sharpest hour. Answer fast, bookmark anything uncertain, and return to bookmarks with your remaining time. Results arrive quickly after submission, and a pass adds PSM I to your Scrum.org profile permanently.

If you fail, you buy another attempt and take it once your practice scores say you are ready — there is no waiting period drama, just the fee. Treat a near-miss diagnostically: your score report's subject areas tell you where the final push belongs.

Where the PSM sits in the wider scrum master landscape

One sentence each, because these questions have dedicated articles: if you are weighing Scrum.org's exam-only model against the Scrum Alliance's course-based Certified ScrumMaster, our CSM vs PSM comparison gives the two-way verdict; the full scrum master certifications round-up surveys every credential beyond these two; and the complete money picture — fees, retakes, renewals and a budget study route — lives in scrum master certification cost and preparation.

Frequently asked questions

What score do I need to pass PSM I?

85%. With 80 questions, that means missing no more than about 12 — a high bar that rewards precise Scrum Guide knowledge over general agile experience.

Does PSM I expire?

No. All Scrum.org certifications are valid for life, with no renewal fees or continuing-education requirements.

Do I need to take a course before PSM I?

No — self-study is a fully supported route. Scrum.org's optional courses include a free exam attempt, which changes the economics if you wanted formal training anyway.

How long should I study for PSM I?

There is no official figure, and it varies with your starting point. A useful signal is performance, not hours: consistent 85%-plus scores on full-length timed practice tests indicate readiness better than any calendar rule.

Is PSM I proctored?

No — it is an online, un-proctored assessment taken on your own computer. The 60-minute limit across 80 questions is the practical safeguard: there is no time to rely on looking things up.

Booking your first attempt with confidence

The Professional Scrum Master track rewards a particular kind of candidate: one willing to trade classroom structure for self-directed rigour. PSM I asks for $200, an exacting 85% pass mark and genuine precision about what Scrum is — and in return gives you a lifetime credential from the organisation of Scrum's co-creator, with PSM II and III waiting when your experience deepens.

Your path from here is short and concrete: read the 2020 Scrum Guide twice, clear the free Scrum Open assessment until it is trivial, then drill full-length timed practice tests until 85% is your floor rather than your ceiling. When the checklist above is all ticks, buy the attempt password and sit it that week.
