Professional Scrum Master I (PSM I): The Exam Facts, Cost, and What It Actually Tests

What This PSM I Exam Actually Certifies

Professional Scrum Master I(PSM I) doesn't certify that you attended a class — it certifies that you can answer detailed, scenario-based questions about the Scrum Guide correctly, under time pressure, without a course as a safety net. Scrum.org, founded by Scrum co-creator Ken Schwaber, built PSM I specifically to break from the "pay for a seat, get a certificate" model common elsewhere in the Agile certification market. You buy an assessment attempt, not a course.

Passing proves you know the current Scrum Guide cold: the three roles (Product Owner, Scrum Master, Developers), the five events, the three artifacts plus their commitments, and the accountabilities of a Scrum Master specifically — not just general Agile theory.

Who This PSM I Exam Is For (and Who It's Not For)

PSM I fits people who already have some exposure to Scrum in practice — even a few sprints as a Developer or Product Owner counts — and want a credential that doesn't require sitting through a mandatory course. It also suits experienced Scrum Masters coming from a different certification body (Scrum Alliance's CSM, for instance) who want a body of knowledge check that's independent of any single trainer's interpretation.

It's a poor fit for someone who has never seen a Scrum team operate and wants structured, guided learning before being tested — the self-study path assumes you can read and internalize the Scrum Guide unsupervised. It's also not a management or "Agile leadership" certification; it stays narrowly focused on the Scrum Master accountabilities as written.

PSM I Exam Format and Structure

Eighty questions in sixty minutes works out to about 45 seconds per question on average — but the distribution isn't even. A handful of straight recall questions ("how many days is a Sprint Retrospective timeboxed to for a two-week Sprint?") take five seconds. Multi-select "choose all that apply" questions, where partial credit generally isn't given, take much longer, especially when the Scrum Guide's wording allows more than one technically defensible answer.

The test is open-book in the sense that nothing physically stops you from having the Scrum Guide open in another tab — but the clock doesn't stop, and at 85% you have almost no margin for looking things up you should already know. Most people who fail don't fail on obscure trivia; they fail on questions that test whether they've internalized the guide's actual wording rather than the looser, popularized version of Scrum many teams practice day to day (e.g., treating the Daily Scrum as a status meeting, or believing the Scrum Master assigns work).

Domains and Topics Covered

Scrum.org organizes PSM I content around three Focus Areas from its Professional Scrum Competencies. It does not publish percentage weightings for how many questions come from each area, so treat any specific percentage breakdown you see elsewhere as an unverified estimate.

The heaviest weight in practice, based on the structure of the Scrum Guide itself, sits with the first area — if you know the Events, Artifacts, and the Scrum Master's specific service to each of the three roles precisely as the guide defines them, you've covered most of the exam's actual difficulty.

Cost Breakdown

A single attempt is $200 USD, paid directly to Scrum.org when you purchase your assessment password. That password never expires — you can sit the test whenever you're ready, with no forced deadline. If you fail, there's no automatic free retry; you buy another $200 attempt.

The one exception: candidates who complete an official, Scrum.org-licensed instructor-led PSM course and attempt PSM I within 14 days of receiving their free password get a second attempt at no additional cost if they don't pass the first time. Course prices are set independently by each licensed trainer and commonly run from roughly $1,000 to $2,000 for a two-day class — Scrum.org doesn't set or publish a fixed course fee, so treat any specific course price you see as that provider's rate, not an official one.

Prerequisites and Eligibility

There are none. No required course, no minimum experience, no application or approval process. You create a free Scrum.org account, purchase an attempt, and you're eligible to sit the exam immediately. This is a deliberate design choice — Scrum.org's entire certification model is built around testing knowledge directly rather than gatekeeping access to the test.

How the Exam Is Scored and What Passing Requires

You need 85% — 68 correct answers out of 80 — to pass. That's a notably high bar compared to most professional certifications, and it's one of the most commonly misunderstood facts about PSM I among first-time candidates who assume it's closer to a typical 70% pass line. There's no partial credit on multi-select questions in the sense of getting close; you generally need every correct option selected and no incorrect ones. Results are shown immediately after submission, and Scrum.org issues a Credly digital badge automatically to those who pass.

Renewal and Recertification

PSM I certification does not expire. There's no continuing education requirement, no SEUs to accumulate, and no renewal fee — ever. This is one of the clearest practical differences between PSM I and Scrum Alliance's CSM, which requires renewal every two years along with a fee and continuing education units. Once you have PSM I, it's yours permanently, regardless of whether you keep working as a Scrum Master.

How PSM I Compares to Its Closest Alternative: CSM

The most common comparison candidates make is against the Certified ScrumMaster (CSM) from Scrum Alliance, and the two differ in almost every way that matters for a decision.

Neither is objectively "better" — they reflect different philosophies. CSM guarantees a shared classroom experience and a live trainer, which some employers and some learners genuinely value; PSM I assumes you can and will study independently, and rewards that with a much lower total cost and a certification that never lapses. In US and Gulf-region hiring, CSM sometimes carries more brand recognition simply because it's older and more widely held; in Europe and in product-led tech companies, PSM I is frequently viewed as the more rigorous of the two because of its pass-rate difficulty and lack of a guaranteed course-completion path.

Preparation Timeline

For someone who has worked on an actual Scrum team for at least a few months, two to four weeks of focused evening study — reading the Scrum Guide multiple times, working through the free Scrum Open assessment repeatedly until scoring consistently above 90%, and reviewing specific terminology (the guide is precise about words like "accountability" versus "role," which changed in the 2020 revision) — is a runway.

For someone new to Scrum entirely, plan on six to eight weeks, and seriously weigh whether a short course would shorten that runway enough to be worth the cost. The exam's difficulty comes less from length and more from precision: it penalizes people who know Scrum "in spirit" but haven't memorized where the guide draws hard lines.
