PSM vs CSM: Which Scrum Certification Should You Get?
Choose PSM I if you want the cheaper, rigorous, no-expiry option you can self-study; choose CSM if you'd benefit from a mandatory two-day course and your employer is paying.
PSM and CSM are the two best-known Scrum Master certifications, from two different organizations. They teach similar fundamentals, so the real decision comes down to cost, whether you want a mandatory course, and whether the credential expires.
Head-to-head comparison
| Factor | PSM I (Scrum.org) | CSM (Scrum Alliance) |
|---|---|---|
| Course required | No — you can take the exam directly | Yes — mandatory two-day course |
| Typical cost | $200 exam (under $300 self-study) | ~$800–$1,500 (course included) |
| Exam difficulty | Harder: 85% to pass, closed-book | Easier pass threshold, course-supported |
| Expiry / renewal | Never expires, no renewal fee | Renew every 2 years (fee + SEUs) |
| Best for | Self-funded, budget-conscious learners | Those wanting a guided course, employer-paid |
Why choose PSM I
- Far cheaper if you self-study — just the $200 exam plus optional prep
- No mandatory course, so experienced people can test straight out
- No expiry and no renewal fees — pay once, keep it for life
- Its tougher exam is seen by some employers as a stronger signal
Why choose CSM
- The mandatory two-day course gives structure and live instruction
- Great when your employer pays, which removes the cost objection
- The Scrum Alliance brand is very widely recognized by recruiters
- A gentler exam experience if you're nervous about self-testing
The bottom line
Both are legitimate. For most self-funded learners, PSM I is the better value; for employer-sponsored learners who want a live course, CSM is fine. Either way, a Scrum certification pairs naturally with understanding Agile versus Waterfall, and fits into the path to becoming a Scrum Master.
