✅ Currently Recommended by Clarke
The MS-900 is a solid entry-level credential for anyone working in or transitioning into a Microsoft 365 environment — cloud productivity, collaboration, security, and compliance concepts. It’s particularly useful for DoD contractors and enterprise IT professionals where M365 is the standard productivity platform. Clarke holds this cert and recommends it as an accessible starting point for the Microsoft certification track.
BLUF: To pass the MS-900, do 4 things
- Create a public contest with another person to complete the MS-900 before they complete a similar educational objective. Accountability accelerates everything.
- Microsoft Learn’s free MS-900 learning path is excellent — do it entirely on your phone. It’s short enough to complete in a weekend of commute and downtime.
- Buy a practice test resource primarily for the digital test bank. Run all questions once, rerun only wrong answers until zero remain, then restart with real exam-length mixed sets until 90%+.
- Don’t over-study. This is a fundamentals exam. Test when you’re consistently over 80% on practice. The re-take is your safety net.
What Is the MS-900?
The Microsoft MS-900 (Microsoft 365 Fundamentals) certification validates foundational knowledge of Microsoft 365 cloud services, including:
- Cloud concepts and Microsoft 365 productivity solutions
- Microsoft 365 security, compliance, privacy, and trust
- Microsoft 365 pricing, licensing, and support
It’s the entry point for the Microsoft 365 certification track, equivalent to AZ-900 for the Azure track. Both are worth having if you work in a Microsoft-heavy enterprise or DoD environment.
📋 Recommended Path
Consider pairing MS-900 with AZ-900 and AI-900 — together they cover the full Microsoft cloud landscape: productivity, infrastructure, and AI. All three are approachable fundamentals-level exams.

Test Methodology
Clarke’s practice test approach for all Microsoft fundamentals exams:
- Microsoft Learn first — complete the entire free path. It’s short and directly exam-mapped.
- All questions once — work through every practice question in your test bank.
- Wrong answers only — loop through only missed questions until zero wrong answers remain.
- Mock exam sets — run full-length, timed, mixed-domain practice exams until consistently over 90%.
- Test on schedule — don’t delay once you hit 80%+ consistently. Re-takes are cheap; over-studying is time you won’t get back.
