The exam

What is the GH-900 exam?

GH-900 is the GitHub Foundations certification — the standard starting point for anyone who collaborates on GitHub. It's owned and maintained by GitHub but delivered through Microsoft's exam platform, and it's designed for non-developers and developers alike: project managers, technical writers, product owners, and engineers all sit it.

The exam validates that you understand:

GH-900 is conceptual rather than hands-on — it doesn't ask you to write code or configure a CI pipeline from scratch. What it does expect is a clear working model of how GitHub fits together, explained clearly enough to defend in a team conversation:

Microsoft and GitHub last updated the GH-900 study guide on 19 February 2026, with the skills outline reworked in January 2026. Every question in Azure Mastery's GH-900 bank is mapped to the current seven-domain outline, including newer topics like Copilot agents and Enterprise Managed Users. Read the official outline at learn.microsoft.com.

GH-900 exam objectives

Seven domains, with weights set by GitHub's February 2026 study-guide update. Each domain below carries GitHub's own skill-group wording verbatim from the official outline, so you can see precisely which domain a topic belongs to and where the gaps are.

Aura presents a visual map of planning, coding, secure delivery, and deployment skills.

Understand Privacy, Security, and AdministrationPublished weight 10–15%

48 exam-scoped practice questions in the app

Explore Security topics
  • Security and access management
  • A described outcome traces back to one specific setting, and pinning it down is the whole question.
  • Personal settings like 2FA get blurred with organisation-wide controls such as Enterprise Managed Users policy.
  • Learn exactly which force-pushes and unreviewed merges branch protection actually stops.

Explore the GitHub CommunityPublished weight 5–10%

28 exam-scoped practice questions in the app

Explore Community topics
  • Open-source engagement
  • Why GitHub's open-source features work the way they do is the underlying question in this domain.
  • This domain gets skipped as unimportant, and questions on Sponsors or InnerSource get missed as a result.
  • Learn what InnerSource actually borrows from open-source collaboration habits.

Common traps

Where GH-900 candidates slip

Three recurring misconceptions that trip up otherwise well-prepared GH-900 candidates, grounded in the current skills outline.

Git and GitHub answer different questions, and GH-900 tests the boundary directly

Candidates new to source control often use the two names interchangeably, and the boundary between them is what gets tested.

  • The exam is testing whether you know Git tracks commit history offline and GitHub hosts the pull request review.
  • Read whether a stem asks about tracking history or about hosting collaboration before answering.

github.dev and Codespaces are not the same "edit in the browser" feature

github.dev is a lightweight in-browser editor with no compute behind it, while Codespaces spins up a full dev container.

  • A quick typo fix calls for github.dev; running a build calls for Codespaces, and that split is exactly what's scored.
  • Check whether the scenario needs real compute before choosing between the two editors.

A fork and a branch solve different collaboration problems

A branch is a parallel line of work in the same repository; a fork is a full copy under a different account.

  • An external contributor without write access needs a fork, not a branch, and that call is the crux of it.
  • Check who holds write access to the original repository before choosing between the two.

How Azure Mastery helps you pass GH-900

Exam-specific practice

  • 347 GH-900 practice questions, tagged against all seven published domains.
  • Git and GitHub basics carries the most weight at 25–30% and underpins the other six.
  • Practise matching a task to the exact GitHub feature it needs.

Predicted score

  • Exam IQ predicts your GH-900 score on-device after roughly 30 questions, with a confidence range attached.
  • GH-900 spreads its questions across seven domains, so the prediction draws on a broad range of topics.
  • Get the foundational Git-and-GitHub domain right and the rest of the score tends to follow.

Adaptive study plan

  • Miss a branch-protection question and the next session surfaces another from that same domain.
  • Master explaining the GitHub Flow three sessions running and the plan moves on to newer material.
  • The plan front-loads the basics domain before spreading across repositories and collaboration.

Knowledge decay

  • Vocabulary learned in week one — forks, branches, issues — slips first once you move to a new domain.
  • Azure Mastery catches that drift early instead of waiting for a mock exam to reveal it.
  • Weak-spot drills resurface a fading topic before a whole domain quietly goes stale.

Exam rehearsal

  • 100-minute timed sessions give a genuinely new GitHub user a full-length rehearsal.
  • The mix is weighted to all seven published domain percentages, built from original questions.
  • GitHub controls the live interface and exact item mix, not this app.

Answer Coach

  • Starts from whichever idea you picked — Git vs GitHub, fork vs branch — then walks you to the right one.
  • What sticks is the distinction, not a definition you half-knew already.
  • Every miss goes into your missed-answers list with an authored explanation attached first.

Aura guidance

  • Aura front-loads the basics domain during week one before easing into repositories and collaboration.
  • Each session signs off with a short note on what changed and where to look next.

Private by design

  • Your GH-900 answer history, readiness prediction, and coaching stay on your device.

Frequently asked

GH-900 FAQs

How much does the GH-900 exam cost?

The GitHub Foundations exam is USD $99, a price set by GitHub rather than Microsoft's standard certification pricing. GH-900 is delivered through Microsoft's exam platform, but the certification itself is owned and maintained by GitHub.

Does the GH-900 GitHub Foundations certification expire?

Yes. Unlike Microsoft's own Fundamentals certifications such as AZ-900, which never expire, GitHub Foundations is valid for two years from the date you pass. To stay certified, you re-sit GH-900 — GitHub sets this two-year validity, not Microsoft.

What is the GH-900 retake policy if I fail?

GH-900 follows the standard Microsoft exam-delivery retake policy even though GitHub owns the credential.

  • First retake: after 24 hours.
  • Second, third, fourth, and fifth retakes: a 14-day wait each.
  • Cap: five attempts in any rolling 12-month period, each needing a fresh booking.
GH-900 vs AZ-900 — what's the difference?

GH-900 validates collaboration on GitHub: Git, repositories, pull requests, Actions, and the open-source community. AZ-900 validates cloud concepts and core Azure services. They're independent credentials in different product families, and DevOps-minded candidates often earn both.

What should I expect from GH-900's exam format?

GitHub gives candidates 100 minutes and says the question count can vary. Azure Master's original practice bank weights single-answer and scenario items most heavily, with multi-select, drag-to-match, and hotspot questions included for broader interaction practice.

Is GH-900 worth taking if I'm not a developer?

Yes — GH-900 is explicitly designed for non-developers as well as developers. Project managers, technical writers, and product owners all sit it to prove they can collaborate effectively on GitHub. It doesn't ask you to write code, just to explain how the platform's features fit together.

GH-900 vs GH-300 — foundations or the Copilot-specific exam?

GH-300 narrows in on one tool: using Copilot responsibly, prompting it well, and administering it at scale. GH-900 is the broad on-ramp with no assumed Copilot depth. Non-developers usually stop at GH-900; developers proving Copilot fluency move on to GH-300.

Can I try Azure Mastery's GH-900 content before paying?

Yes. The app is free to download, with a free allowance of GH-900 questions to try every feature first. The full bank unlocks with a one-time exam-pack purchase, or unlock every exam with a subscription or lifetime upgrade.

Does GH-900 practice work offline?

Yes — GH-900 practice runs its questions, scoring, and readiness prediction entirely on-device, so a commute or flight with no connection doesn't interrupt your revision. No account is needed, and data stays on your device unless you enable iCloud sync.
