SC-401 Renewal and Retakes Explained

The short version

The credential you earn with SC-401 expires one year after you earn it, unless you renew it. Renewal is free: you pass a short, open-book online assessment on Microsoft Learn during the six months before the expiry date. If you fail the exam itself, you wait 24 hours for the second try and 14 days between later tries, with at most five attempts in 12 months.

Does the credential expire?

Yes. SC-401 leads to the Microsoft Certified: Information Security Administrator Associate credential. Microsoft’s expiration policy says associate and expert credentials are valid for one year from the date you complete all requirements. The exam page repeats the point: role-based and specialty certifications expire unless they are renewed.

This is different from fundamentals credentials, which Microsoft says do not expire. If you are used to a fundamentals exam, plan for a yearly task here.

How renewal works

Microsoft describes renewal in a few steps:

  1. Sign in to your Microsoft Learn profile and connect it to your certification profile.
  2. Look for the Renew button next to the credential. It appears only when you are eligible.
  3. Refresh your skills with the free modules on the renewal page.
  4. Pass the online assessment before the credential expires.

A few details matter more than they look:

  • The window is six months. You cannot renew earlier than six months before the expiry date. Microsoft recommends not waiting for the last week, because illness, a technical problem, or a few failed tries can eat your time.
  • It is free. Microsoft states that renewal costs nothing.
  • It is short and open book. The assessment is not proctored and focuses on recent updates to the technology. Microsoft says it takes about 45 minutes.
  • You can retry. There is no limit on renewal attempts. After a failed first try you can try again right away, and after the second try you wait at least 24 hours between attempts. Just pass before the expiry date.
  • The date updates immediately. After you pass, your Learn profile shows the new expiry date, one year after the old one.
  • There is no other route. Microsoft says you cannot renew by retaking the exam or by passing a beta exam. Only the renewal assessment counts.

Because Purview changes often, the renewal assessment is a useful yearly nudge to read what is new. It tests updates, not the whole outline again.

What happens if it lapses?

Once the expiry date passes, you can no longer renew. Microsoft’s policy says you must earn the credential again by passing the required exam. The renewal button does not come back.

The good news is that the retake rule allows it: you cannot retake an exam you have passed unless the credential has expired, and an expired one counts. So a lapsed holder simply books SC-401 again. Expect the exam to look different from your first attempt, because the skills outline moves.

Retake rules for the exam

Microsoft’s retake policy for role-based exams is:

  • After your first failed attempt, wait 24 hours.
  • After that, wait 14 days between attempts, up to five attempts.
  • No more than five attempts in 12 months, counted from your first attempt. After five failures you can try again 12 months after the first one.
  • You cannot retake an exam you passed, unless the credential has expired.
  • You pay for every retake. Microsoft prices the exam by country, so check the amount when you book.

The waiting period can be waived in one case only: an internet or equipment failure during the exam, with a Pearson VUE case number. Microsoft says no other reason qualifies.

When the exam changes

Microsoft updates the English exam first and the localized versions about eight weeks later. The study guide is titled “Skills measured as of October 28, 2026”, and Microsoft updated the English exam on that date. In its change log only the sensitivity labels area is marked as a minor change; the audience profile and the information protection group are unchanged, and the log lists no other area.

Three practical points follow:

  • If you booked for another language, the older outline may still apply for a while. Check which one applies to your date and language.
  • If you fail near a change, your retake may fall under a newer outline. Read the study guide again before you rebook.
  • If you hold the credential, your expiry date does not move because the exam changed. The yearly renewal assessment follows the exam updates.

A timeline example

Say you pass on March 3. Your credential then runs until March 3 of the next year. The renewal window opens in early September, six months before that date. You open your profile in October, take the assessment, and pass on the second try. Your new expiry date is one year after the old one, so March 3 two years later.

Now say you ignore the reminders and the date passes. From March 4 you cannot renew, and you would book SC-401 again.

What Microsoft does not publish

  • The exam fee in a single figure. Microsoft says only that the price depends on the country or region where the exam is proctored.
  • The number of questions. Only a general range for Microsoft exams exists.
  • A retirement date for SC-401. The pages we read list none.
