- Domain 1: Scrum tests the Scrum Guide, Scrum values, and the three pillars, not opinions or frameworks outside Scrum.
- You have 1 hour for 50 questions, so Domain 1 concepts need to be instantly recognizable, not slowly reasoned out.
- A passing score is 37 out of 50 (74%), so weak recall on Domain 1 basics puts real pressure on the other domains.
- The exam is open-book, but Domain 1 questions are written to test understanding, not lookup speed.
What Domain 1 Actually Covers
Domain 1: Scrum is the foundation layer of the Certified ScrumMaster exam. Where Domain 2 tests how you behave as a facilitator and coach, and Domain 3 tests how you serve the broader organization, Domain 1 tests something more basic: do you actually know what Scrum is, as defined by the Scrum Guide and the CSM Learning Objectives?
This matters because Scrum Alliance built the current CSM exam around the Scrum Foundations learning objectives and the Scrum Guide itself, with the learning objectives last updated in January 2022 and reformatted in February 2024. That means Domain 1 questions are not testing folklore or "how my last team did Scrum" - they're testing the source material. If you want the full breakdown of how all three domains relate to each other and how weight is distributed across them, the CSM Exam Domains 2026 guide is the companion piece to this article.
Core Topics You Must Master
Domain 1 is broad but not vague. Based on the Scrum Guide and the published CSM learning objectives, candidates should expect direct, definitional questions on the following:
Scrum Definition and Purpose
You need to know Scrum as "a lightweight framework that helps people, teams, and organizations generate value through adaptive solutions for complex problems" - not as a project management methodology or a set of ceremonies.
- Scrum is a framework, not a full process or methodology
- Scrum is intentionally incomplete - teams layer other practices on top of it
- Scrum is used for complex, adaptive work, not simple or well-understood problems
The Scrum Team and Its Accountabilities
Expect questions distinguishing the three accountabilities: the Product Owner, the Scrum Master, and Developers. Questions often test boundaries - what a Scrum Master can and cannot dictate, and what belongs solely to the Developers or Product Owner.
- The Scrum Team is self-managing and cross-functional
- No sub-teams or hierarchies exist within the Scrum Team
- The whole Scrum Team is accountable for creating a valuable, useful Increment every Sprint
Scrum Values
Commitment, Focus, Openness, Respect, and Courage. These are commonly tested as scenario-matching questions: a short situation is described, and you must identify which value is being demonstrated or violated.
- Memorize all five values and a one-line definition of each
- Practice recognizing values in behavioral, not just definitional, form
Scrum Values, Pillars, and Theory
Scrum theory is one of the most commonly under-studied parts of Domain 1 because it feels abstract. Candidates often skim past transparency, inspection, and adaptation to get to the "practical" material - but the exam does not skip it.
- Transparency: significant aspects of the process must be visible to those responsible for the outcome; questions test what happens when transparency is compromised.
- Inspection: Scrum artifacts and progress toward goals must be inspected frequently, but not so frequently that inspection gets in the way of the work.
- Adaptation: when inspection reveals deviation, an adjustment must be made as soon as possible.
Expect at least a few questions per attempt that describe a scenario and ask you to identify which pillar is missing or which pillar a particular event primarily serves. This is a favorite pattern because it's easy to write many variations of the same underlying concept.
Key Takeaway
Don't just memorize the three pillars - practice mapping each Scrum event to the pillar it most directly supports. The Daily Scrum is inspection-heavy; the Sprint Review is transparency-heavy; the Retrospective is adaptation-heavy.
Scrum Events and Artifacts
This is the densest part of Domain 1 and where most exam points live. You need fluent recall of five events and three artifacts, including their purpose, timebox, and required participants.
| Scrum Event | Purpose | Typical Timebox (1-month Sprint) |
|---|---|---|
| Sprint | Container for all other events; creates consistency | 1 month or less |
| Sprint Planning | Lay out the work for the Sprint | Max 8 hours |
| Daily Scrum | Inspect progress toward the Sprint Goal, adapt the plan | 15 minutes |
| Sprint Review | Inspect the outcome, adapt the Product Backlog | Max 4 hours |
| Sprint Retrospective | Plan ways to increase quality and effectiveness | Max 3 hours |
On artifacts, know the Product Backlog, Sprint Backlog, and Increment - and, critically, each artifact's commitment: the Product Goal for the Product Backlog, the Sprint Goal for the Sprint Backlog, and the Definition of Done for the Increment. Exam writers frequently swap these commitments in wrong-answer choices, so precision matters more than general familiarity.
How Domain 1 Questions Are Written
The CSM exam consists of 50 multiple-choice questions delivered through the Scrum Alliance online test portal - not Pearson VUE, PSI, or Prometric - in a 1-hour window that cannot be paused. Scrum Alliance does not publish a scored versus unscored breakdown, so treat every question as if it counts.
Domain 1 questions tend to fall into three recognizable formats:
- Direct definitional recall: "Which of the following best describes the Sprint Backlog?" These are the fastest points on the exam if you know the Scrum Guide language.
- Scenario matching: A short situation is described, and you identify which value, pillar, or event applies. These require you to translate real-world behavior into Scrum Guide vocabulary.
- Elimination-based questions: Several answers sound plausible, but only one aligns exactly with the Scrum Guide's wording. Domain 1 rewards precision over general Agile knowledge picked up from other frameworks.
Because the test is open-book, some candidates assume they can look everything up. In practice, a 1-hour timebox for 50 questions gives you a little over a minute per question on average - not enough time to search the Scrum Guide repeatedly. For a deeper look at why this format catches people off guard, see How Hard Is the CSM Exam? Complete Difficulty Guide 2026.
Key Takeaway
Treat the open-book format as a safety net, not a strategy. Know Domain 1 material cold so you only need to check the Scrum Guide on a handful of genuinely tricky questions.
A Domain 1 Study Sequence
Because Domain 1 is foundational, it makes sense to study it first and revisit it throughout your prep window. Here's a sequence that works well alongside your required 16-hour CSM course.
Scrum Guide Immersion
- Read the Scrum Guide twice - once for overview, once annotating definitions
- Build flashcards for the five Scrum values and three pillars
- Attend or complete your live CSM course with a Certified Scrum Trainer
Events and Artifacts Drilling
- Memorize timeboxes, purposes, and commitments for every event and artifact
- Practice scenario questions that ask "which pillar/value applies here?"
- Work through CSM practice questions focused specifically on Domain 1 wording
Integration with Domains 2 and 3
- Connect Domain 1 concepts to Scrum Master facilitation scenarios
- Take full-length timed practice runs on our CSM practice test platform
- Review any missed questions against the exact Scrum Guide language

Common Mistakes on Domain 1 Questions
- Confusing Scrum with generic Agile: Domain 1 tests Scrum specifically. Kanban, SAFe, or general Agile terminology can appear as distractor answers.
- Blurring event purposes: Mixing up what happens in Sprint Planning versus the Sprint Review is one of the most common wrong-answer patterns.
- Treating the Scrum Master as a manager: Domain 1 (and Domain 2) consistently test that the Scrum Master serves, facilitates, and removes impediments rather than assigns tasks or manages people.
- Skipping the "why": Memorizing timeboxes without understanding the underlying pillar (transparency, inspection, adaptation) makes scenario questions much harder.
- Overusing the open-book allowance: With a 1-hour non-pausable timer, relying on lookups for basic Domain 1 facts eats time you'll need later in the test.
How Domain 1 Fits the Bigger Picture
Passing the CSM exam requires 37 correct answers out of 50 (74%), and Domain 1 is the layer that makes the other two domains answerable. Once you're fluent in Domain 1 material, Domain 2's facilitation and coaching scenarios and Domain 3's organizational-service questions become much easier to reason through, because you're no longer stopping to recall basic definitions mid-question.
It's also worth remembering the exam sits inside a larger certification path. The required course is taught by a Certified Scrum Trainer, and public course pricing ranges roughly from $250 to $2,495 depending on the trainer, with two test attempts included and a 90-day window to use them. If you fail twice or run past 90 days, additional attempts cost $25 each. For the full cost picture, including renewal at 20 SEUs and a $100 fee every 2 years, see the CSM Certification Cost 2026 breakdown.
Employers hiring for Scrum Master, Agile Coach, and Product Owner-adjacent roles expect this foundational fluency as a baseline, not a differentiator - it's assumed you know Domain 1 cold. If you're evaluating whether the credential is worth pursuing at all, the Is the CSM Certification Worth It? Complete ROI Analysis 2026 article and the CSM Salary Guide 2026 both go into how this certification is used in the hiring market, while CSM Jobs looks at where the demand actually is.
If you're still early in researching the credential itself, it helps to step back and confirm the basics first - start with What Is CSM Certification? or CSM Certification for the full overview, and CSM Training for how the required course works before you sit the test.
Frequently Asked Questions
Scrum Alliance does not publish official domain weightings, so no domain is confirmed as "largest." However, Domain 1: Scrum covers foundational material that underpins questions in Domain 2 and Domain 3, so weak Domain 1 knowledge tends to cost points across the whole exam.
The current CSM exam is based on the CSM Learning Objectives, the Scrum Foundations learning objectives, and the Scrum Guide. Domain 1 questions draw primarily from these official sources rather than outside Agile frameworks or company-specific practices.
Technically yes, but the exam is 50 questions in 1 hour with no pause option, which leaves little time for repeated lookups. Candidates who know Domain 1 definitions and event details from memory move much faster through the test.
Passing requires 37 out of 50 correct answers (74%). Because Domain 1 concepts recur inside Domain 2 and Domain 3 scenario questions, solid Domain 1 recall effectively helps you across more than a third of the exam's total questions.
Most candidates study Domain 1 first since it's foundational, then move to Domain 2: Scrum Master Core Competencies and Domain 3: Service to the Scrum Team, Product Owner, and Organization, revisiting Domain 1 concepts as they reappear in applied scenarios.
