What Is GH-300 Certification?

What GH-300 Actually Is

GH-300 is the certification code for GitHub Copilot Certification, a credential built to validate that a developer can use GitHub Copilot effectively, responsibly, and securely across real development workflows. GitHub owns and maintains the certification, but the exam itself is developed and published through Microsoft Learn, and it's scheduled and delivered by Pearson VUE. This three-party structure trips up a lot of first-time candidates, so if you're still sorting out the basics, our companion piece on GH-300 Meaning breaks down exactly what each party is responsible for.

Unlike a general programming certificate, GH-300 is narrowly scoped to Copilot itself - how it's enabled, configured, prompted, and governed inside an organization. That focus is what makes it valuable to employers who want proof that a candidate isn't just "using AI autocomplete" but actually understands Copilot's architecture, data handling, and administrative controls.

Exam Format and Logistics

The exam is proctored and lasts 100 minutes. You can sit it at a physical Pearson VUE test center or through online remote proctoring, whichever fits your schedule better. Question formats mix multiple-choice, multiple-response, and scenario-based items, and the exam may also include interactive components rather than sticking to plain text questions.

A passing result requires a scaled score of 700 or higher. Scaled scoring means the raw number of correct answers isn't a 1:1 percentage - different question weights factor into the final score. For a full breakdown of how the scoring works and what 700 actually represents, see GH-300 Passing Score 2026: Exactly What You Need to Pass.

The Six Exam Domains

GH-300 is organized into six domains, each with its own weight on the exam. Understanding these weights should directly shape how you allocate study time. For a domain-by-domain deep dive, our GH-300 Exam Domains 2026: Complete Guide to All 6 Content Areas article expands on each one in detail.

Most items on the exam cover generally available (GA) features, but commonly used Preview features can also appear, so don't assume anything still in Preview is automatically out of scope. If a Preview feature has meaningful adoption in real workflows - Agent Mode capabilities are a good example - expect it to show up.

The remaining five domains split the rest of the exam roughly evenly, with responsible use (15-20%) as the second-largest chunk. That domain covers appropriate use cases, bias and limitation awareness, and knowing when Copilot output needs human review - themes that recur throughout the exam even inside feature-focused questions. If you're trying to gauge how tough this mix actually is in practice, How Hard Is the GH-300 Exam? Complete Difficulty Guide 2026 walks through where most candidates lose points.

Who Should Take GH-300

GitHub sets the level at Intermediate and there are no formal prerequisites - you don't need a prior certification or a specific job title to register. That said, the audience profile assumes three things: practical hands-on experience using GitHub Copilot for productivity, code quality, and security; solid familiarity with GitHub fundamentals (repos, pull requests, branching); and experience with at least one programming language.

In practice, this makes GH-300 a natural fit for:

• Software engineers who already use Copilot daily and want formal recognition of that skill
• DevOps and platform engineers responsible for rolling out Copilot policies across an organization
• Engineering leads who need to understand Copilot's data handling and content exclusion controls before greenlighting adoption
• Developers job-hunting who want a credential that signals AI-tooling fluency to hiring managers

Registration, Fees, and Language Options

The exam costs $99 USD, though the actual charge is set by the country or region where you're proctored, so your local price may differ slightly from the base figure. A full pricing breakdown, including how regional adjustments work, is available in GH-300 Certification Cost 2026: Complete Pricing Breakdown.

GH-300 is offered 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 on top of the standard 100-minute testing time - a detail worth flagging when you book your slot.

One more detail worth knowing: GitHub Student Developer Pack holders can receive a single-use voucher valid for either GH-300 or GH-900, which is a low-cost way for students to attempt the exam. For exact testing windows and how far out you can schedule, see GH-300 Exam Dates 2026: Testing Windows, Deadlines & Scheduling.

Validity, Renewal, and Retakes

The certification expires annually. Renewal, however, is free and handled through an online assessment on Microsoft Learn - you don't have to retake the full proctored exam or pay the $99 fee again each year, which is a meaningfully lighter lift than many other technical certifications require.

If you fail on your first attempt, you can retake the exam after a 24-hour waiting period. Later retakes carry progressively longer waiting periods, so it pays to prepare thoroughly rather than treat the exam as a low-stakes guess-and-check process. Microsoft also sells Exam Replay bundles if you want a built-in second attempt purchased upfront.

How to Approach Preparation

Given the domain weighting, the most efficient prep sequence starts with Domain 2 (Use GitHub Copilot Features) since it's worth the most points, then moves through responsible use, architecture, prompt engineering, productivity, and privacy/safeguards in roughly descending order of weight. A light spaced-repetition pass in the final days - revisiting flashcards on feature names, REST API endpoints, and audit log events - helps lock in the terminology-heavy parts of Domain 2 without burning fresh study time.

Running timed practice questions on our GH-300 practice test platform is one of the most direct ways to get comfortable with the scenario-based question style before exam day, and reviewing a condensed reference like the GH-300 Cheat Sheet 2026: One-Page Review of Must-Know Facts in the final week can help consolidate what you've already learned.
