GitHub Certification Exam Prep

GitHub's certification track has two rungs. GH-900 GitHub Foundations is the entry point: it validates that you understand Git and GitHub from first principles — version control concepts, repositories, commits and branches, the GitHub Flow, and the collaboration surfaces (issues, pull requests, discussions) that day-to-day work runs on. It is deliberately not a developer-only exam: project managers, technical writers, and administrators who work inside GitHub are part of the target audience, and the questions test recognition and understanding rather than hands-on configuration. Expect roughly 75 questions over 120 minutes, with a scaled passing score of 700 out of 1000.

The Foundations blueprint (refreshed January 2026) spans seven domains. Git and GitHub basics carries the heaviest weight at 25–30%, followed by working with repositories, collaborating on GitHub, modern development practices (GitHub Actions, the Copilot plan tiers, Codespaces and github.dev), project management with Projects, privacy, security and administration, and the GitHub community — open source, Sponsors, InnerSource, and the Marketplace.

GH-300, the Copilot certification, sits above Foundations and covers considerably more than knowing how to accept a suggestion. It validates that you can work with Copilot across its surfaces (the IDE, the CLI, github.com and mobile) and that you understand what happens to your code along the way: how prompts are assembled, what the proxy filters, and where the model's limits sit. The exam runs 100 minutes with roughly 60 questions and a 70% passing score — and it is not solely a developer credential either, since organization-wide policy management, content exclusions, audit log events and subscription management through the REST API are all in scope.

Career value: Foundations signals platform fluency for any role that touches GitHub and is the natural first step, while the Copilot credential signals both effective AI-assisted development and an understanding of the governance that has to sit around it. Taking them in that order — GH-900, then GH-300 — mirrors how organizations actually adopt the platform: collaboration first, AI enablement second.
