High school can be a great time to start contributing to open-source software: you can learn how real projects are built with other people, explore subjects that interest you, and make small contributions without waiting to become an expert. It is not the perfect time for everyone, and you do not need a formal summer program to begin.
What you can learn by contributing
Open-source projects give you a chance to see how software work happens beyond writing code alone. Google’s guide to Google Summer of Code (GSoC) describes learning outcomes that include distributed development, version control, software licensing, testing, and communication. Those practices matter whether you later work on software professionally or simply want to understand how the tools you use are made.

A contribution does not have to be a major feature. Reading a project’s documentation, trying its setup instructions, reporting a reproducible issue, or improving a small piece of documentation can help you understand how contributors coordinate work. The project’s own contribution guidance should determine what is useful and how to submit it.

- Choose something you care about. Start with a project or tool you already use, or a subject you want to explore. Interest makes it easier to stay curious when setup or review takes time.
- Read the project’s contribution instructions. Look for guidance on setting up the project, finding tasks, communicating with maintainers, and submitting changes. Do not assume every repository has beginner-friendly issues.
- Pick a modest, clearly scoped task. A small change is easier to understand, test, and review than a large feature. If a task is unclear, ask a focused question in the project’s recommended channel before investing substantial effort.
- Follow the project’s process and respond to feedback. A pull request is a proposal for maintainers to review, not a guarantee that the change will be accepted. Review comments can show you how the project works and what it expects.
GitHub Education’s Intro to Open Source offers beginner exercises and an opportunity to get a first pull request merged. It is one structured starting point; you can also approach a project directly if it clearly explains how newcomers can participate.

How to choose a welcoming project
When you compare projects, look beyond whether the code seems interesting. Google’s 2023 study of open-source participation identifies a welcoming community, clear onboarding, and a code of conduct among the leading criteria contributors consider when choosing projects. Use those as practical signals, alongside whether the project has a task that fits your interests and current experience.
- Onboarding: Can you find understandable setup and contribution instructions? Is there a clear way to ask questions?
- Community expectations: Does the project explain how participants should treat one another and what behavior is expected?
- Task and interest: Is there a manageable first step connected to something you genuinely want to learn or improve?
These signals cannot guarantee that a project will be a good fit or that a contribution will be merged. They can help you decide where to spend your limited time. The community and onboarding criteria are discussed in Google’s 2023 open-source participation study.
Rank #2
Do you need to be an expert programmer?
No. Beginner exercises and small, well-scoped contributions can help you learn the project while participating. Some tasks do require specific technical knowledge, so read the task description and project guidance rather than assuming every issue marked “good first issue” will be easy. You can begin with what you can understand, ask a precise question when you are stuck, and build skills through the work.
Are high school students eligible for Google Summer of Code?
Not if they are under 18. The current GSoC student guide says that, since 2022, students and beginner contributors aged 18 or older may apply. GSoC is a global online mentoring program; its mentors help participants learn a community, codebase, and testing practices. It is one route into open source, not a prerequisite for making contributions.
Program figures show its scale, not an individual applicant’s odds. Google’s 2025 contributor statistics report that 43.04% of that year’s contributors had not contributed to open source before the program. The same report lists 15,240 applicants, 23,559 proposals, and 185 participating organizations. Those are GSoC 2025 figures, not high-school-specific statistics.
The GSoC guide reports that, as of December 2025, the program had brought together 43,000 contributors and mentors from more than 150 countries, with more than 1,000 projects having participated. These cumulative program figures describe its reach; they do not establish an individual’s likelihood of acceptance or guarantee a job or other outcome.
What about Outreachy?
Outreachy says it helps newcomers to free software and open source make their first contributions. Its applicant guide says university students need 42 consecutive days free from school and exams during the internship period. That guidance does not establish whether high-school students are eligible, so check Outreachy’s current applicant information rather than assuming you qualify.

Is high school the right time for you?
It can be, especially if you have time to explore a project and are interested in learning how people build software together. But there is no established statistic showing that high school is better than another age or life stage for starting. Your schedule, interests, experience, and the communities available to you all matter. A small contribution to a project you care about can be a useful beginning; there is no need to wait for a selective program or to treat open source as a race.
