What Is A GH-300?

What Exactly Is a GH-300?

GH-300 is the exam code for the GitHub Copilot Certification, a credential designed to validate that a developer can use GitHub Copilot productively, securely, and responsibly across the software development lifecycle. It is not a generic "AI tools" certificate - it specifically tests hands-on knowledge of Copilot's features inside real developer workflows, from inline code completion to chat-based debugging to organization-level policy management.

If you've landed here after seeing conflicting information elsewhere, it's worth being precise: this article covers only the GitHub Copilot Certification exam. For a deeper breakdown of naming conventions and why "GH-300" specifically maps to this credential, see GH-300 Meaning and What Does GH-300 Stand For?.

Who Maintains and Delivers the Exam

The certification itself is maintained by GitHub, but the exam content is published and hosted on Microsoft Learn. Scheduling and proctoring go through Pearson VUE, and candidates can choose between an in-person test center or online remote proctoring, whichever fits their schedule and comfort level better.

This three-party structure - GitHub as credential owner, Microsoft Learn as content publisher, Pearson VUE as testing administrator - is standard for exams in this ecosystem, so if you've taken other Microsoft-published certifications before, the registration and check-in process will feel familiar.

Exam Format, Timing, and Question Style

GH-300 is a 100-minute proctored exam. It mixes multiple-choice and multiple-response questions with scenario-based items that describe a realistic development situation and ask you to choose the best Copilot-related action. Some items may also include interactive components rather than plain static text.

• Testing time: 100 minutes total
• Question types: multiple-choice, multiple-response, scenario-based, and interactive components
• Delivery: proctored, either at a Pearson VUE test center or via online remote proctoring
• Passing score: a scaled score of 700 or greater

Because scenario-based questions dominate the harder portions of the exam, memorizing feature names alone won't get you through. You need to understand which Copilot capability applies to which situation. For a full sense of how difficult that actually is in practice, read How Hard Is the GH-300 Exam? Complete Difficulty Guide 2026.

The Six Domains You're Tested On

GH-300's content is organized into six weighted domains. Understanding the weighting is essential for allocating study time efficiently - a candidate who spends equal time on every domain is almost certainly under-preparing for the heaviest one.

For a much deeper walkthrough of each domain - including sub-topics and how questions are typically framed - see GH-300 Exam Domains 2026: Complete Guide to All 6 Content Areas.

Registration, Fees, and Language Options

The exam costs $99 USD, though the exact amount charged depends on the country or region where you're proctored. It's available in English, Spanish, Portuguese (Brazil), Korean, and Japanese. If the exam isn't offered in your preferred language, you can request an additional 30 minutes to account for translation time while reading.

One detail worth flagging: GitHub strongly recommends registering with a personal Microsoft account rather than a work account, so your certification record survives a change of employer. This is easy to overlook during a rushed registration flow, but it matters if you ever switch companies and want to keep your credential attached to you rather than a defunct corporate login.

Students holding a GitHub Student Developer Pack can also receive a single-use voucher valid for either GH-300 or the GH-900 exam - a useful cost-saving path if you're still in school.

Who Should Actually Take This Exam

GH-300 is classified as Intermediate level. There are no formal prerequisites, but the audience profile GitHub describes assumes:

• Practical, hands-on experience using GitHub Copilot for productivity, code quality, and security tasks
• Familiarity with GitHub fundamentals (repositories, pull requests, branches, workflows)
• Working experience in at least one programming language

In practice, this means the exam suits developers who already use Copilot daily - not newcomers trying to learn Copilot for the first time from a study guide. If you're unsure whether you meet the bar, GH-300 Requirements 2026: Eligibility, Prerequisites & How to Qualify breaks down exactly what "practical expertise" looks like in this context.

Employers hiring for roles that involve AI-assisted development, developer productivity tooling, or platform engineering increasingly look for this credential as a signal that a candidate can operationalize Copilot beyond basic autocomplete.

Passing Score, Retakes, and Annual Renewal

You need a scaled score of 700 or greater to pass - there's no raw percentage published, so don't try to reverse-engineer "how many questions you can miss." For a full explanation of how scaled scoring works, see GH-300 Passing Score 2026: Exactly What You Need to Pass.

If you don't pass on your first attempt, you can retake the exam after a 24-hour waiting period. Subsequent failed attempts come with progressively longer waits, so it pays to prepare thoroughly rather than treat the first sitting as a "practice run." Microsoft also sells Exam Replay bundles if you want a built-in second attempt baked into your purchase.

Once earned, the certification expires annually. Renewal, however, is free and happens through an online assessment on Microsoft Learn - no need to resit the full 100-minute proctored exam every year. This annual cycle exists because Copilot's feature set changes quickly, and GitHub wants certified holders to stay current.

Building a Domain-Aware Study Plan

Because Domain 2 (Use GitHub Copilot Features) carries the most weight at 25-30%, it deserves the largest share of study time - particularly the newer areas like Agent Mode, Copilot Edits, MCP, and Agent Sessions and Sub-Agents, which are easy to underestimate if your hands-on Copilot use hasn't touched them yet. Pair that with lighter, steady review of the four mid-weight domains (Data and Architecture, Prompt Engineering, Productivity, and Privacy/Safeguards), each sitting at 10-15%.

Whatever schedule you follow, running realistic timed practice questions on our practice test platform before exam day is one of the most reliable ways to get comfortable with the scenario-based question style GH-300 relies on. Repeated exposure to that format on our GH-300 practice tests matters more than passively re-reading notes.
