The Complete PSM I Exam Guide (2025)

The PSM I exam (Professional Scrum Master I) is one of the most respected entry-level Scrum certifications available. Unlike many certifications that reward attendance, PSM I tests your actual understanding of the Scrum Guide 2020. If you want to pass it on your first attempt, you need a clear study plan and an honest picture of what the exam demands.

What the PSM I Exam Actually Tests

The PSM I is not an experience test. It does not ask you to reflect on past projects or describe what you did in a given situation. It tests your knowledge of the Scrum Guide 2020 — the single authoritative source for Scrum — and your ability to apply that knowledge to realistic scenarios.

Scrum.org designs questions to expose common misconceptions. You will encounter scenarios where a team is doing something that feels reasonable but contradicts the Scrum Guide. Your job is to identify the correct course of action according to Scrum, not according to common sense or your workplace experience.

Key topics include:

• The three Scrum accountabilities: Scrum Master, Product Owner, Developers
• The five Scrum events and their timeboxes
• The three Scrum artifacts and their commitments
• The meaning of empiricism and the three pillars: transparency, inspection, adaptation
• The Sprint Goal and its role in giving the team flexibility

Exact Exam Format

Knowing the format removes surprises on exam day.

• Questions: 80 multiple-choice and true/false questions
• Time limit: 60 minutes
• Pass threshold: 85% — you need at least 68 out of 80 correct
• Cost: $150 USD per attempt
• Delivery: Online, taken from anywhere, no proctor required
• Open book: Technically yes — but 60 minutes for 80 questions leaves you roughly 45 seconds per question. Looking things up mid-exam is not a viable strategy. Treat it as closed book during your preparation.

You receive your result immediately after submitting. There is no waiting period.

How to Study for PSM I

1. Read the Scrum Guide 2020 three times

The Scrum Guide is only 13 pages. Read it once for comprehension, once to take notes on anything that surprises you, and once more the week before your exam. Many candidates skim it once and assume they know it. They do not. Pay close attention to exact language — the Guide is precise by design.

2. Do practice questions early and often

Do not save practice questions for the end. Start them after your first read-through. Questions reveal your blind spots faster than re-reading does. Aim for at least 200–300 practice questions across multiple sessions.

3. Focus on edge cases

The exam is designed to distinguish candidates who have surface-level knowledge from those who understand the reasoning behind Scrum. Edge-case topics include:

• Can the Sprint be cancelled? (Yes — only by the Product Owner)
• Who creates the Sprint Goal? (The entire Scrum Team during Sprint Planning)
• Can Sprint Backlog items change during a Sprint? (Yes — with the consent of Developers)
• Is the Daily Scrum only for the Developers? (Yes — others may attend but do not participate)

4. Understand, do not memorise

Memorising answers to practice questions will fail you. Understand why each answer is correct according to the Scrum Guide. The exam rephrases scenarios — the reasoning stays the same, the wording does not.

5 Most Common Mistakes Candidates Make

1. Applying workplace Scrum instead of guide Scrum. Many teams run hybrid or modified versions of Scrum. What your team does is irrelevant. What the Scrum Guide says is everything.

2. Confusing accountabilities. The exam frequently tests whether candidates know what falls under the Scrum Master, Product Owner, or Developers. The Scrum Master does not manage the Developers. The Product Owner does not assign tasks.

3. Misunderstanding timeboxes. Timeboxes are maximums, not targets. A Daily Scrum can end in 10 minutes. A Sprint Review does not have to last 4 hours. Knowing this distinction matters for exam questions.

4. Treating the Sprint Review as a demo. The Sprint Review is an inspection of the Increment and adaptation of the Product Backlog. It is a collaborative working session with stakeholders, not a one-way presentation.

5. Underestimating the pass threshold. 85% sounds achievable until you realise that means you can only get 12 questions wrong out of 80. Candidates who do moderate preparation are often surprised by how close the margin is.

The Day Before the Exam

Do not cram. The day before should be about consolidation, not new information.

• Do one final read of the Scrum Guide — particularly the sections on artifacts and their commitments
• Review your notes on topics where you scored poorly in practice
• Do a short set of 20–30 practice questions to stay sharp, not to learn new material
• Confirm your exam environment: stable internet, quiet space, working browser
• Get a full night of sleep — decision fatigue is real at question 60 of 80

On exam day, read each question carefully. The PSM I is known for questions where one word changes the correct answer. If you have studied the Scrum Guide thoroughly, trust your preparation and move steadily through the questions.

The PSM I certification is a genuine test of Scrum knowledge. Candidates who respect it and prepare systematically pass it. Those who treat it as a formality usually do not.
