Certified ScrumMaster (CSM) prep, adaptive plan with ARIA
Certified ScrumMaster (CSM) is the Scrum Alliance entry-level Scrum cert and the most-recognized agile credential in 2026. The exam runs 60 minutes, 50 questions, multiple choice, online proctored. Passing is 74 percent, meaning 37 of 50 correct. The certification is valid for two years. One thing to know before you start. The CSM requires completion of a two-day instructor-led course as a prerequisite, so you cannot self-study and sit the exam.
What the exam is
| Focus area | Weight |
|---|---|
| Lean, Agile, and Scrum framework | ~25% |
| Scrum events | ~20% |
| Scrum roles (Product Owner, ScrumMaster, Developers) | ~20% |
| Scrum artifacts and the Definition of Done | ~15% |
| Scaling, coaching, and ScrumMaster mindset | ~20% |
How 
ARIA preps you for it
The two-day course covers the framework. My job is the gap between the course and the exam, plus the long retention after. A CAT evaluation lands a per-area skill estimate within the first sitting, so we are not guessing where you are weak. The roadmap weights phases toward your weakest area, not the syllabus average. Every miss enters the error backlog tagged by trap pattern (Waterfall vocabulary appearing inside a Scrum question, mixing ScrumMaster and Project Manager responsibilities, conflating the Definition of Done with acceptance criteria). Tagged items return at widening intervals until they stop being misses.
Common pitfalls
- Treating the ScrumMaster as a project manager. Several questions test whether you reach for command-and-control answers under pressure. The right answer is almost always servant leadership.
- Confusing the Definition of Done with acceptance criteria. DoD is a team-wide quality gate; acceptance criteria are story-level. Common trap.
- Skipping scaling and the ScrumMaster mindset section. It is the smallest weight by points but the highest weight by exam-stress factor, since questions are written ambiguously.
Prerequisite
You must complete a two-day instructor-led CSM course from a Scrum Alliance Certified Scrum Trainer before sitting the exam. Course cost is typically $700 to $1500. ClaudeLab does not replace that course. I complement it, focused on retention and exam prep across the months between class day and test day.
Pass guarantee
Same five conditions as every cert on the platform, with a full refund if you complete the roadmap and do not pass within the 60-day window. The course fee itself is not covered, since that money goes to Scrum Alliance, not to ClaudeLab.
