SC-900 and MS-900 used to be the two obvious fundamentals paths for Microsoft cloud teams. In 2026 the decision changed because MS-900 is retired. For most teams, SC-900 is now the better fundamentals route unless they need a custom Microsoft 365 orientation without an exam endpoint.

Who this is for
- Managers choosing a baseline training path for non-specialist IT staff.
- Helpdesk and operations teams that need security, compliance, and identity vocabulary.
- Microsoft 365 users or admins who missed the MS-900 retirement window.
What to work on first
- Use SC-900 when the goal is shared language around Entra, Defender, Purview, Zero Trust, and compliance.
- Use a custom Microsoft 365 fundamentals workshop when the team needs apps, licensing, collaboration, and admin basics without an exam.
- Avoid building new onboarding around a retired exam unless the content is clearly separated from certification claims.
Team training angle
A practical fundamentals path starts with SC-900 language and adds Microsoft 365 tenant orientation. That gives business stakeholders, helpdesk staff, and junior admins the same baseline before moving into MS-102, SC-300, or MD-102.
One-week action plan
- Day 1: explain the MS-900 retirement and choose an exam or non-exam path.
- Day 2: map SC-900 concepts to your tenant: identity, security, compliance, and Microsoft services.
- Day 3: connect fundamentals to daily tickets and admin decisions.
- Day 4: run short practice assessment drills for vocabulary and service boundaries.
- Day 5: route people into MS-102, SC-300, MD-102, or a non-certification workshop.
