AZ-900 Retake Rules: Waiting Period, Costs & What to Expect

What are the AZ-900 retake rules?

Direct Answer: You must wait 24 hours after your first failure before retaking AZ-900. After a second failure, the waiting period increases to 14 days. Each retake costs the full exam fee (~$99 USD). There is no limit on total attempts.

Just failed AZ-900 and wondering what happens next? How long do you have to wait? Do you have to pay again? Did you somehow break any rules?

These are the questions everyone has—and the answers are simpler than you might think. Microsoft’s retake policy is actually pretty clear and predictable. No hidden penalties, no permanent marks on your record, no complicated procedures.

Let me break down everything you need to know.

Can You Retake AZ-900 After Failing?

Yes, absolutely. Microsoft lets you retake the exam after failing. There’s no permanent penalty, and you can try as many times as you need until you pass.

Failed attempts are invisible to employers or anyone outside Microsoft’s certification portal. Only you can see your exam history. When you eventually pass, that’s the only result that matters—nobody will ever know how many attempts it took.

Microsoft treats each attempt independently. Failing once doesn’t affect your eligibility for future exams or certifications in any way.

Just failed? You might find it helpful to understand what to do in the first 7 days after failing.

How Long Do You Have to Wait?

Microsoft enforces a mandatory waiting period between attempts. Here’s how it works:

First retake: Wait 24 hours after your failed attempt
Subsequent retakes: 24 hours between each additional attempt
After passing: You can’t retake it (you’ve earned the certification)

Important: The waiting period applies to when you take the exam, not when you book it. You can schedule your retake immediately, but the exam date has to be at least 24 hours after your previous attempt.

Why the Waiting Period Exists

Microsoft does this to:

Prevent people from just memorizing questions through rapid retakes
Encourage actual learning between attempts
Maintain exam integrity and keep the certification valuable

For most people, 24 hours is a pretty short wait. In practice, you’ll probably want more time to review and prepare properly anyway.

How Many Times Can You Retake AZ-900?

There’s no maximum. You can retake the exam as many times as you need to pass.

Each attempt is treated independently:

Previous failures don’t affect future attempts
Your score doesn’t “carry over” between attempts
Only your passing result matters for certification

This policy applies to all Microsoft Fundamentals exams. Microsoft doesn’t penalize persistent effort—they want people to succeed eventually.

Worried about failing multiple times? Remember: plenty of successful certified professionals needed more than one attempt. The certification doesn’t show how many tries it took.

Do You Have to Pay Again?

Yes, normally you pay the exam fee again for each retake. Microsoft doesn’t automatically provide free retakes after failing.

What you need to know about costs:

The retake fee is typically the same as the original exam fee
Pricing varies by region and currency
Discounts may be available through employers, schools, or Microsoft Learn promotions
Payment is required when you book the retake, not when you take it

If cost is a concern, check whether your organization offers certification benefits. Many employers reimburse exam fees, especially for role-relevant certifications like AZ-900.

Is There Any Way to Get a Free Retake?

Not automatically, but sometimes yes. Here are situations where you might not have to pay:

When Free Retakes Might Be Available

Microsoft Learn Cloud Skills Challenges: Some promotional events include exam vouchers or retake vouchers
Microsoft Virtual Training Days: Attending certain Microsoft training events can provide free exam vouchers
Employer or school programs: Some organizations purchase exam packs that include retake options
Microsoft Certified Trainer benefits: MCT members sometimes receive exam vouchers

Common Misconceptions

“Everyone gets one free retake” — Nope. Free retakes are promotional, not standard
“Microsoft automatically refunds failed attempts” — Nope. The exam fee is non-refundable
“Student accounts get free retakes” — Not automatically. Students may get discounts but not guaranteed free retakes

If you’re unsure whether you have retake benefits, check your Microsoft Certification Dashboard or contact your organization’s training administrator.

Should You Switch to a Different Microsoft Exam?

You can, but you probably shouldn’t.

Microsoft doesn’t require you to pass AZ-900 before taking other exams. But switching after failing is usually a mistake for beginners.

Why Switching Is Often Wrong

AZ-900 tests foundational cloud concepts that appear in all Azure exams
If you failed AZ-900, you’ll likely struggle with more advanced exams (AZ-104, AZ-204, etc.)
Switching out of frustration doesn’t address the underlying knowledge gaps
AZ-900 concepts are building blocks for everything else in Azure

When Switching Might Make Sense

You discover Azure isn’t relevant to your career path
Your organization requires a different certification immediately
You were already experienced with cloud and AZ-900 was just a formality

For most beginners, the right move is to retake AZ-900 with better preparation—not to switch to something harder or unrelated.

When Should You Actually Retake?

Just because you can retake after 24 hours doesn’t mean you should. Rushing back into the exam without changing your approach usually produces the same result.

Why Immediate Retakes Often Fail

The same knowledge gaps produce the same mistakes
Emotional frustration affects focus and performance
“More hours” doesn’t fix conceptual misunderstandings

What Works Better

Most people who pass on their second attempt wait 1–4 weeks before retaking. This gives you time to:

Identify specific weak areas (pricing, shared responsibility, service types, etc.)
Re-learn concepts with focus on understanding, not memorization
Practice exam-style questions to test your improved knowledge
Enter the exam with confidence, not desperation

Use the Waiting Period Well

The waiting period is an opportunity, not a setback:

Review what confused you during the exam
Focus on conceptual understanding, not just facts
Practice with questions that explain why answers are correct or incorrect
Build confidence through structured preparation

How Certsqill Helps

People who pass AZ-900 on their second attempt usually stop watching random tutorial videos and start practicing structured, exam-style questions with detailed explanations.

That’s what Certsqill is built for:

Fundamentals-focused content that targets the concepts AZ-900 actually tests
Clear explanations for every answer—so you understand why you got it right or wrong
Beginner-friendly structure that builds confidence for the retake

The goal is to replace guessing with reasoning. When you understand the concepts behind each question, passing becomes predictable.

Frequently Asked Questions

How long do I have to wait before retaking AZ-900?

24 hours after a failed attempt. This applies to each retake. You can book your next attempt immediately, but the exam date has to be at least 24 hours later.

Do I have to pay again if I fail AZ-900?

Yes, Microsoft requires payment for each exam attempt. Retakes cost the same as the original fee. Some promotional programs or employer benefits may provide free retakes, but that’s not standard policy.

Is there a free AZ-900 retake?

Not automatically. Free retakes are sometimes available through Microsoft promotional events, employer programs, or training benefits—but they’re not guaranteed. Check your certification dashboard or organization’s training resources.

How many times can I retake AZ-900?

No limit. You can retake as many times as needed until you pass. Each attempt is independent, and only your passing result matters.

Can I take another Microsoft exam instead of retaking AZ-900?

Yes, Microsoft allows you to take any exam at any time. However, switching to a different exam after failing AZ-900 usually isn’t recommended for beginners, since AZ-900 covers foundational concepts needed for all Azure certifications.

Moving Forward

Microsoft’s retake policy is straightforward: wait 24 hours, pay the exam fee, and try again. No hidden rules, no permanent penalties, no limit on attempts.

Failing AZ-900 once is common—especially for first-time cloud exam takers. The waiting period isn’t punishment; it’s an opportunity to prepare properly and return with confidence.

Use this time to understand what went wrong, focus on conceptual gaps, and practice with purpose. When you’re ready, the retake will feel very different from the first attempt.

The certification is waiting for you.
