Scrum Master Certification Guide: PSM vs CSM and How to Choose
The two most popular Scrum Master certifications are PSM I from Scrum.org and CSM from Scrum Alliance. PSM I is exam-only: no course is required, the exam is demanding, and the certification never expires. CSM requires a two-day course with a Certified Scrum Trainer, has an easier exam, and renews every two years. Choose PSM I to prove knowledge at lower cost; choose CSM if you want structured live training included.
Key takeaways
- PSM I: exam-only, lifetime validity, demanding pass mark.
- CSM: mandatory course, live learning and networking, renewal required.
- Both are built on the official Scrum Guide. Read it several times.
- Certification opens doors; facilitation experience gets you hired.

What a Scrum Master actually does
- Facilitates Scrum events: sprint planning, daily scrum, review and retrospective
- Removes impediments that slow the team down
- Coaches the team and organisation in Scrum and agile practices
- Helps the product owner manage the backlog effectively
It’s a facilitation and coaching role, not a traditional “manager” role. For how Scrum fits alongside other approaches, see agile vs waterfall.
How to prepare for PSM I
- Read the Scrum Guide (it’s short) at least three times.
- Take Scrum.org’s free open assessments until you consistently score near 100%.
- Learn the why behind each rule, because questions test understanding, not memorisation.
- Study terms like accountability, commitment, increment and Definition of Done precisely.
How to choose
- Budget-conscious and a confident self-studier? PSM I.
- Want interactive live training and a community? CSM.
- Targeting a specific employer? Check which one their job ads mention.

Frequently asked questions
What is the difference between PSM and CSM? +
PSM I (Scrum.org) requires only passing a demanding online exam, with no mandatory course, and doesn't expire. CSM (Scrum Alliance) requires attending an approved course taught by a Certified Scrum Trainer, then passing a shorter exam, and must be renewed every two years.
Which Scrum certification is more respected? +
Both are widely recognised. Some employers see PSM I's harder exam as a stronger knowledge signal; others value CSM's mandatory live training. Check which appears more often in job listings in your market.
Can I become a Scrum Master without experience? +
A certification helps you get interviews, but Scrum Master roles usually want some team or delivery experience. Many people move in from developer, tester, business analyst or project coordinator roles.
How hard is the PSM I exam? +
It requires a high pass mark and close reading of the Scrum Guide. Candidates who study the Scrum Guide thoroughly and take Scrum.org's free open assessments repeatedly tend to do well.
