Professional Scrum Master I
Who this exam is for
The Professional Scrum Master I certification is designed for professionals who work with or want to work with Scrum.org technologies in a professional capacity. It is taken by cloud engineers, DevOps practitioners, IT administrators, and technical professionals looking to validate their expertise.
You do not need extensive prior experience to attempt it, but you will benefit from hands-on familiarity with the subject matter. The exam tests applied knowledge and architectural judgment, not just memorization. If you can reason about trade-offs and real-world scenarios, structured practice will handle the rest.
Domain breakdown
The PSM I exam is built around official domains, each with a fixed percentage of the question pool. This distribution should directly inform how you allocate your study time.
Note the domain with the highest weight — many candidates under-invest here because it feels conceptual. In practice, this is where the exam is most precise, with scenario-based questions that test specifics.
What the exam actually tests
This is not a memorization exam. Questions require applied judgment under constraints. Almost every question includes a scenario with explicit requirements and asks you to select the most appropriate solution.
Here are examples of the question types you will encounter:
How to prepare — 4-week study plan
This plan assumes one hour per weekday and roughly 30 minutes of lighter review on weekends. It is calibrated for someone with some relevant experience. If you are starting from zero, add an extra week before Week 1 to familiarise yourself with the basics.
- Read the 2020 Scrum Guide word-for-word three times; on the third pass, highlight every accountability, time-box figure, and commitment statement.
- Create a Scrum reference card: five events with time-boxes, three artifacts with commitments, three accountabilities with their service statements.
- Take the free Scrum.org "Scrum Open" assessment (30 questions); treat your score as a baseline and review every wrong answer against the Guide.
- Study the Scrum Master's three areas of service: to the Scrum Team, to the Product Owner, and to the organisation — list two actions for each area.
- Study each event in depth: what question each event answers, who attends, who facilitates, and what the output or outcome is.
- Practise distinguishing Product Backlog refinement (ongoing activity) from Sprint Planning (event): both involve the backlog but serve different purposes.
- Review Definition of Done in detail: who creates it, who enforces it, and what happens when an increment does not meet it.
- Complete a 40-question multiple-select drill; for any question answered incorrectly, re-read the relevant Scrum Guide paragraph before moving on.
- Sit a full 80-question timed mock assessment; you need 85% to pass, so treat any mock score below 88% as a signal to continue drilling.
- Review the Nexus Guide (scaling Scrum) and the Evidence-Based Management Guide — PSM I occasionally includes questions from these complementary Scrum.org resources.
- Study technical debt, velocity, and team metrics: how a Scrum Master coaches the team to address debt without compromising the Definition of Done.
- Target "Scrum in Practice" domain questions specifically — these are the most varied and rely on applying multiple Scrum concepts simultaneously.
- Complete two more full 80-question timed mocks; you need consistent scores of 88–90% to have confidence in passing the 85% threshold.
- Re-read your reference card daily using active recall: cover the answers and force yourself to state them before uncovering.
- Review the PSM I assessment format: 80 questions in 60 minutes means 45 seconds per question — practise pacing during your final mocks.
- On exam day, log in to your Scrum.org account 15 minutes early, confirm your browser is compatible, and do not spend more than 90 seconds on any single question.
Common mistakes candidates make
These patterns appear repeatedly among candidates who resit this exam. Knowing them in advance is worth several percentage points.
