What is the GitHub Administration certification?

The GitHub Administration certification is earned by passing Exam GH-100: GitHub Enterprise Administrator. It validates that you can manage identities and access with SAML SSO, SCIM and enterprise managed users, administer GitHub Enterprise Cloud and Server deployments, enforce security and compliance policies, govern GitHub Actions at company scale, and monitor license and usage. The study guide is published on Microsoft Learn.

How much does the GitHub Administration certification cost?

Microsoft's published exam pricing feed lists GitHub certification exams under a single GH family code at $99 in the United States. GH-100 does not appear under its own code, so no source can honestly quote a GH-100-specific figure beyond that family price. Confirm the fee at registration before you book.

What is on the GH-100 exam?

Five domains: manage GitHub identities and access (15 to 20 percent), administer the GitHub Enterprise environment (10 to 15 percent), implement secure software development and compliance (25 to 30 percent, the biggest), manage GitHub Actions (20 to 25 percent), and monitor and optimize GitHub usage (10 to 15 percent). Security plus Actions governance is 45 to 55 percent of the paper.

Did the GitHub Administration exam change in 2026?

Yes, and very recently. The official change log states the exam changed significantly in July 2026: objectives added, removed, moved and reworded. The current outline names GHEC with Data Residency plus EMU as a deployment scenario, Azure private networking for runners, third-party vault integration for secrets, and metered product cost optimization. Prep material written before mid-2026 predates all of it.

How hard is the GitHub Administration certification exam?

The identity work most admins expect is only 15 to 20 percent. The biggest domain is secure software development and compliance at 25 to 30 percent, and GitHub Actions governance adds 20 to 25 percent more. If you administer users but have never rolled out CodeQL, secret scanning policies or runner groups, the majority of the paper sits outside your daily work.

How many questions are on the GH-100 exam?

Neither GitHub nor Microsoft publishes an official question count for GH-100. The certification page does state the time limit: you will have 100 minutes to complete the assessment, and the exam is proctored. Treat any site quoting an exact question count as unofficial.

Is the GitHub Administration certification worth it?

For platform engineers, GitHub Enterprise admins and DevOps leads who own an organization's GitHub estate, it is directly job-shaped: identity, governance, Actions policy and license management are the actual responsibilities. It signals enterprise-scale operation rather than personal proficiency, which is what hiring managers screening for platform roles look for.

The GitHub Administration certification is earned by passing Exam GH-100: GitHub Enterprise Administrator. It has five domains, you get 100 minutes, and Microsoft's pricing feed lists GitHub exams under one family code at $99 US. The surprise is the weighting: manage identities and access, the work everyone associates with admins, is only 15 to 20 percent. The biggest domain is secure software development and compliance at 25 to 30 percent, with GitHub Actions governance at 20 to 25 percent right behind it. The official change log says the exam changed significantly in July 2026, adding objectives on GHEC with Data Residency, Azure private networking for runners and third-party vault integration that no pre-2026 prep covers.

What GH-100 actually tests: security first, users second

We read the official skills-measured outline on Microsoft Learn the way we do for every certification page on this site. In the roughly 380-word outline, enterprise appears 10 times, and the security domain outweighs the identity domain by ten points. This is an exam about running GitHub as corporate infrastructure, not about adding people to teams.

Domain	What is actually in it	Weight
Implement secure software development and compliance	The biggest domain. Organization and enterprise policies, rulesets, audit logging and reporting, vulnerability alerts, secret scanning and CodeQL enablement, Dependabot and security advisories, a security response plan, PAT and GitHub App rate limits, and approving apps by policy.	25 to 30%
Manage GitHub Actions	Governing automation, not writing it: reuse policies for actions and workflows, organizational Actions policies, GitHub-hosted vs self-hosted runner options, runner groups, IP allow lists and networking including Azure private networking, secret scoping at organization and repository level, and third-party vault integration.	20 to 25%
Manage GitHub identities and access	Managed users vs personal accounts, SAML SSO and 2FA enforcement, SCIM vs team sync and their key differences, choosing identity providers, organization and repository roles, enterprise teams, and access audits.	15 to 20%
Administer GitHub Enterprise environment	The four deployment scenarios (GHEC with EMU, GHEC with Data Residency plus EMU, GHEC with personal accounts, GHES), licensing and billing models, license consumption monitoring, support bundles and diagnostics, and defining workflow, branching, review and release standards.	10 to 15%
Monitor and optimize GitHub usage	Audit log and API usage analysis, spotting underutilized features and adoption patterns, interpreting usage reports for metered products, and license and resource cost optimization.	10 to 15%

Add it up: security plus Actions governance is 45 to 55 percent of the paper. An admin who manages users and repos all day but has never rolled out CodeQL, written an Actions use policy or built a runner group is underprepared for most of the exam. Build questions from the current study guide instead: generate practice questions from your own admin notes and weight them to the five real domains.

GH-100 has an official Microsoft practice assessment worth taking at least once. Neither GitHub nor Microsoft publishes a question count or a pass rate on the study guide. The certification page states the time limit: 100 minutes, proctored.

The July 2026 rewrite: what is new on GH-100

The official change log on Microsoft Learn states the exam changed significantly in July 2026: objectives added, removed, moved between functional groups, and all reworded. The current outline is stamped "Skills measured as of July 2026." That makes GH-100 one of the freshest outlines in the whole GitHub family, and it dates every course and question bank written earlier. Objectives the current outline names that older prep rarely covers:

GHEC with Data Residency + EMU

The outline now lists four distinct deployment scenarios and expects you to contrast them, including the data residency variant that did not exist when most GH-100 courses were recorded.

Azure private networking for runners

Runner networking goes beyond IP allow lists: the outline names Azure private networking configuration for GitHub-hosted runners explicitly.

Third-party vault integration

Secrets management now includes integrating external vaults, not just GitHub's own encrypted secrets at organization and repository scope.

Metered products and cost optimization

A whole objective on interpreting usage reports for metered products and recommending license and resource optimization. Admins are now expected to own the bill.

The pattern matches what we documented across the family: the GitHub Foundations practice test (GH-900) and the GitHub Actions certification practice exam (GH-200) were rewritten in January 2026, and GH-100 plus GH-500 followed in July. GitHub is refreshing every exam, which quietly expires every static question bank.

Why working GitHub admins still fail GH-100

The exam is written for the person accountable for a whole company's GitHub estate across GHEC and GHES. Compare what routine administration teaches against what the outline asks.

What you know from day-to-day admin work	What the exam also expects
You add users and manage team membership	Contrast SCIM provisioning with team synchronization and explain when each breaks down
Your company uses SSO and it mostly works	Explain managed users vs personal accounts and pick the right deployment scenario, including Data Residency
You enable security features when asked	Define enterprise-wide policies, rulesets and a security response plan, and report through audit logs
Developers run their own workflows	Write organizational Actions policies, govern runner groups with IP allow lists and private networking
Someone in finance handles the invoice	Explain licensing and billing models, monitor consumption, and optimize metered product spend

Every right-hand cell is a named objective on the July 2026 outline. Generated question drills are the cheapest way to find out which of those you can only half-explain, before the proctored clock is running.

How to build GH-100 practice questions that match the real blueprint

The July 2026 rewrite dates every older bank. Build from current material and spend the saved time on the security and governance domains that carry the marks.

1 Upload current material: The GH-100 study guide, GitHub's enterprise docs, or your own notes. If your material never mentions Data Residency or enterprise teams, it predates the current outline.
2 Drill security hardest: Policies, rulesets, audit logging, secret scanning, CodeQL and Dependabot governance add up to the biggest domain. Generate scenario questions until enablement order and policy scope are automatic.
3 Learn the four deployments: GHEC with EMU, with Data Residency plus EMU, with personal accounts, and GHES. Most wrong answers on scenario questions come from mixing up what each one can and cannot do.
4 Finish with the official mock: GH-100 has an official Microsoft practice assessment. Use generated questions to close gaps domain by domain, then confirm readiness on the official mock before booking.
