Short answer: choose SSM if you work, or want to work, in an organisation that runs SAFe - Agile Release Trains, PI Planning, a Release Train Engineer on the org chart. Choose PSM I for everything else. The two certificates do not compete for the same job so much as describe two different ways a company is organised. PSM I costs $200 per attempt at Scrum.org and never expires. SSM now has an exam-only route at $495 with two attempts and renews at $195 a year. Every figure in this article was checked at the publisher on 24 September 2026.
The two exams side by side
| PSM I (Scrum.org) | SSM (Scaled Agile) | |
|---|---|---|
| What it tests | The Scrum Guide (2020) | Scrum inside SAFe: team events, ART events, PI Planning, AI in the role |
| Questions | 80 | 45 |
| Time | 60 minutes | 90 minutes |
| Pass mark | 85% | 80% on the current exam |
| Course required | No | No, since the exam-only route (see below) |
| Exam fee | $200 per attempt | $495 + tax for two attempts (exam-only) or included in the course |
| Renewal | None, valid for life | $195/year + tax and 12 CEUs a year |
| Source | Scrum.org | Scaled Agile |
The time-per-question row matters more than it looks. PSM I gives you 45 seconds a question at an 85% bar, which is why people who "know Scrum from work" fail it - there is no time to reason from habit, only to recognise what the Guide says. SSM gives you two minutes a question at 80%, but a fifth of the content is about events PSM I never mentions.
Full details are on our PSM I exam format and SSM exam format pages.
What changed in 2026: SSM without the course
For years the honest answer to "can I just sit the SSM exam" was no - Scaled Agile gated every SSM attempt behind the 2-day course. When we compared the four SAFe certifications on 18 September, the exam-only footnote appeared on the SAFe Agilist, SAFe Practitioner and POPM pages, but not on SSM.
On 24 September the SAFe Scrum Master page carries the same footnote - "Training course not required" - and a "Purchase Proctored Exam" button. The terms are in Scaled Agile's proctored exams FAQ: "The Proctored exam fee is $495 plus tax and this is non-refundable. Two attempts are included with this fee", within a 60-day window. You take it through the Guardian Browser with webcam, microphone and identity checks. If both attempts fail, a new purchase at $495 is required.
This changes the comparison in one specific way. The strongest practical argument for PSM I used to be that nobody could buy an SSM without first buying a two-day class. That argument is gone. What remains is the difference in price, renewal and - most of all - what the exam tests.
What each exam actually tests
PSM I tests one document. The assessment is grounded in the Scrum Guide 2020, a short text that defines three accountabilities, five events and three artifacts. The difficulty is not volume; it is precision. The exam rewards knowing what the Guide says and punishes workplace folklore - velocity targets, story points, the "three questions" of the Daily Scrum - none of which is in the Guide. Our PSM I vs CSM guide covers that trap in more detail.
SSM tests Scrum as a component of a larger system. The current exam blueprint on the certification page has six domains:
| SSM domain (current exam) | Weight |
|---|---|
| Introducing Scrum in SAFe | 10-12% |
| Characterizing the role of the Scrum Master | 21-23% |
| Participating in PI Planning | 14-16% |
| Facilitating the Iteration Execution | 21-23% |
| Finishing the PI | 14-16% |
| Augmenting the Scrum Master Role with AI | 12-14% |
About half of that - PI Planning, Finishing the PI, the ART context - has no counterpart in PSM I. And SAFe renames some Scrum concepts: the SAFe Scrum Master is a "Scrum Master/Team Coach", sprints are iterations, and a team's work feeds a Program Increment. Someone who has passed PSM I will recognise the team-level mechanics in SSM but still has to learn the vocabulary and the ART layer.
One note on our own material: the SSM practice questions are built against the SAFe 6.0 exam study guide, which used four domains and a 73% pass mark (see the 6.0 study guide). The current exam adds the AI domain and raises the bar to 80%. The team-level and ART content overlaps; the AI domain is not covered by our bank, and we say so on the SSM pages.
Cost: once versus every year
PSM I is the cheapest serious Scrum credential on the market. $200 buys a password for one attempt; according to Scrum.org's own FAQ, passwords do not expire, so you can buy now and sit when ready. A failed attempt means buying another password. Once you pass, there is nothing else to pay, ever.
SSM has two entry routes and one renewal model:
- Course route. The course fee is set by the training provider, not by Scaled Agile, so there is no single price to quote. According to Scaled Agile's retake FAQ, the first two attempts are included in the course registration fee when taken within 60 days, and later retakes cost $50 each, with a 10-day wait before the second retake and 30 days before any after that.
- Exam-only route. $495 plus tax, two proctored attempts in 60 days, $495 again if both fail.
- Renewal. SSM sits in the Foundational tier of SAFe Studio, which renews at $195 a year plus tax, and Scaled Agile's CEU FAQ lists 12 CEUs for SSM. The certification page states the same requirement as 24 CEUs in a two-year cycle.
| Three-year scenario | PSM I | SSM, exam-only route |
|---|---|---|
| Pass first time | $200 | $495 + $195 for each annual renewal |
| One failed attempt | $400 | $495 (second attempt included) + $195 per renewal |
| Stop renewing | Still certified | Certification lapses |
Scaled Agile does not state on the pages we checked whether the first year of Studio membership is bundled with the exam, so we do not total the SSM column - with two renewals inside three years it would be $885.
The renewal row is the one that decides the economics. If your employer pays for SAFe Studio - common in companies that have adopted SAFe at scale - SSM costs you nothing extra to keep. If you are paying yourself and SAFe is not part of your daily work, you are paying $195 a year for a credential your next employer may not ask for. Our certification cost calculator runs these numbers for other combinations.
Which organisation needs which
Choose SSM when: - your company runs Agile Release Trains and PI Planning, or the job advert names SAFe; - you will facilitate ART-level events or work closely with a Release Train Engineer; - your employer will pay for the course or the Studio membership.
Choose PSM I when: - you work in one team, a startup, or a company using plain Scrum, Kanban or its own hybrid; - you are paying yourself and want a credential that does not expire; - you want to prove Scrum knowledge independently of any scaling framework.
Take both, in order, when you are moving into a SAFe organisation without prior Scrum experience. PSM I first: it forces precise knowledge of the Guide at an unforgiving pass mark. SSM second: it adds the ART layer on top of what you already know, and the team-level domains become much easier. The reverse order works less well, because SSM teaches Scrum through SAFe's vocabulary, and PSM I will then penalise every term that is SAFe's rather than the Guide's.
If you are also weighing the rest of the SAFe ladder - SA, POPM, RTE - our SAFe certifications guide compares all four.
How to prepare
For PSM I, read the Scrum Guide several times until you can say which accountability owns every decision, then practise under time pressure. The exam is short enough that pacing is part of the skill. Start with our PSM I practice questions.
For SSM, the course material or the official exam study guide is the backbone, because the exam uses SAFe's own terms. Put extra time into PI Planning and Finishing the PI - the domains a Scrum practitioner has never seen - and, on the current exam, into the AI domain. Our SSM practice questions cover the team and ART domains of the 6.0 blueprint.
