PSM I vs CSM
Direct answer: PSM I (Scrum.org) and CSM (Scrum Alliance) are both Scrum Master certifications, but they fit different learners. Choose PSM I if you want a self-study-friendly assessment with no mandatory class and no renewal. Choose CSM if you want required live training and the Scrum Alliance membership path.
| Category | PSM I | CSM |
|---|---|---|
| Provider | Scrum.org | Scrum Alliance |
| Training required | No mandatory class | Approved CSM course required |
| Exam format | 80 questions, 60 minutes | 50 questions, 60 minutes (format can vary by program updates; confirm with your trainer) |
| Passing score | 85% (68/80) | Typically around 74% historically (confirm current bar with Scrum Alliance / your course) |
| Assessment cost | $200 USD per attempt | Usually included with course registration |
| Renewal | No renewal | Renewal / SEUs required for ongoing status |
| Best for | Self-study candidates and people who want a non-expiring certificate | Learners who want instructor-led training and membership benefits |
Cost model differences
PSM I’s headline cost is simple: pay for the assessment when you are ready. Retakes are paid again. There is no membership renewal to keep the certificate valid.
CSM’s total cost is usually the course fee (which varies widely by market and trainer) plus future renewal investment. That can be worth it if you want classroom discussion, networking, and a guided curriculum — but it is rarely the cheapest path if your only goal is proving Scrum Guide literacy.
Difficulty and exam style
Many candidates report that PSM I feels stricter because of the 85% bar and scenario wording. CSM is not “easy,” but the training path often prepares you differently (live examples, discussions, coach feedback).
