PSM I: the value choice
Scrum.org's PSM I costs $200 per attempt and requires no course. The exam has 80 questions in 60 minutes with an 85% pass mark, and the certification doesn't expire. It's generally considered harder than the CSM test because there's no course and the bar is high.
CSM: training and community
Scrum Alliance's CSM includes a live course with a certified trainer, which many people value for interaction and networking. Course prices vary widely by country and trainer. CSM renews every two years with education units and a fee.
SAFe vs CSM
SAFe certifications teach Scrum within the Scaled Agile Framework used by large enterprises. If job ads mention SAFe, it's worth it; otherwise CSM or PSM is more portable.
Scrum Master certification cost and free options
There's no fully free official Scrum Master certification. Cheap preparation is easy: the Scrum Guide is free, Scrum.org offers free open assessments, and free Science of Apps agile and product certifications let you prove related skills.
After your first Scrum certification
Consider PSM II, A-CSM, PMI-ACP or a product owner certification. Project managers often pair Scrum with the PMP; see PMP vs CAPM vs PRINCE2.
Exam details
- PSM I: 80 questions, 60 minutes, 85% to pass, online, open book; certification never expires.
- CSM: complete a course with a Certified Scrum Trainer, then pass a 50-question online test; renew every two years with education units.
- SAFe Scrum Master: course plus online exam, focused on Scrum within the Scaled Agile Framework; annual renewal.

Which is harder?
PSM I is generally considered harder because there's no course and the pass mark is 85%. CSM is more accessible because the course prepares you directly for the test.
Which do employers ask for?
Most job ads ask for "CSM or PSM" interchangeably. SAFe appears mainly in large enterprises (banking, government, telecom) that run SAFe. Experience facilitating real Scrum teams matters more than which credential you hold.
How to pass PSM I
- Read the Scrum Guide several times; it's the source of truth.
- Take Scrum.org's free open assessments until you score 100% consistently.
- Learn the reasoning behind accountabilities, events and artefacts.
- Book the exam when practice scores stay above 95%.
Scrum Master vs Product Owner certification
Scrum Masters facilitate the team and process; Product Owners own the backlog and value. Choose PSPO or CSPO if you're moving toward product management.
