Is GH-300 hard if I use GitHub Copilot every day? +
Daily use helps less than people expect. GH-300 tests the parts most developers never see: content exclusions, organization policies, audit logs, subscription management, how prompts are built and what data leaves the IDE. It also covers newer features such as agent mode, Copilot CLI and Model Context Protocol. The hard part is admin, privacy and plan-level detail, not writing good prompts.
What is the GH-300 exam format? +
GH-300 is a 100-minute proctored exam that may include interactive components. It is scheduled through Pearson VUE and offered in English, Spanish, Portuguese (Brazil), Korean and Japanese. GitHub provides an exam sandbox demo so you can see the interface first. Check the Microsoft Learn GH-300 page for the current fee, which varies by country or region.
What does GH-300 cover? +
Skill areas include using Copilot responsibly, Copilot features, Copilot data and architecture, prompt engineering and context crafting, developer productivity, and privacy, content exclusions and safeguards. The official study guide lists the current weights. The August 2026 skills update added agent mode, sub-agents, Copilot CLI and MCP, so older prep material may skip whole objectives.
Are there prerequisites for GH-300? +
There are no formal prerequisites. GitHub recommends hands-on expertise with Copilot, familiarity with GitHub fundamentals and experience with at least one programming language. The exam is rated intermediate and aimed at developers, DevOps engineers, app makers and technology managers. Developers who use Copilot daily often need 2-4 weeks focused on admin, policy and data-flow topics.
How long is the GitHub Copilot certification valid? +
GitHub certifications are valid for two years. GitHub is moving to Microsoft's recertification process, which will let holders renew without retaking the full exam, and certifications expiring before that process is available have been extended by six months. Microsoft recommends registering with a personal Microsoft account so your records are not lost if you change employers.
What if I fail GH-300? +
You can retake the exam 24 hours after a failed attempt; waiting periods for later attempts vary under the retake policy. Before rebooking, compare your score report against the skill areas. Most retakers fall short on plan differences, content exclusions and data handling rather than on day-to-day features, so focus there instead of re-reading general Copilot docs.
