What is the difference between PSM I and CSM?

PSM I from Scrum.org costs $200, has no mandatory training, requires 85% to pass, and never expires. CSM from Scrum Alliance requires a paid course, has a 74% pass mark, and expires every 2 years.

How long does it take to prepare for PSM I?

Most candidates study for 2 to 3 weeks with 1 to 3 hours of focused study per day. The Scrum Guide is short but the exam requires deep scenario-based understanding.

Professional Scrum Master I

The problem

The traditional route isn't working.

Expensive courses, passive content, and nothing that prepares you for the actual job.

Too expensive

Certified courses cost £800-£1,200

That's for CSM, which also expires every 2 years with renewal fees. PSM I costs $200 and lasts forever.

Too passive

The Scrum Guide is 13 pages. The exam needs much more.

Reading it isn't the problem. Understanding it deeply enough to answer 80 questions in 60 minutes at 85% is.

Too incomplete

The exam tests knowledge. The role tests people skills.

Facilitating conflict, coaching reluctant teams, and protecting the Sprint are not exam topics. They're day-one requirements.

How Aris prepares you

From zero knowledge to day one.

Study through conversation

An AI tutor presents Scrum scenarios and tests whether you truly understand the principles, not just the definitions.

Practise facilitation

Voice simulations put you in team conflicts, sprint disruptions, and stakeholder pressure situations before they're real.

Prepare for interviews

Scrum Master interviews are behavioural. Rehearse your answers with scored feedback on communication and approach.
