freeCodeCamp.org offers several free developer certifications. Each of these certifications involves completing interactive lessons, workshops, labs and quizzes. Throughout the certification, you will need to complete 5 required projects to qualify for the exam. Once you pass the exam, then you can claim the certification.
Once you've earned a certification, you will always have it. You will always be able to link to it from your LinkedIn or resume. And when your prospective employers or freelance clients click that link, they'll see a verified certification specific to you.
The one exception to this is if we discover violations of our Academic Honesty Policy. When we catch people unambiguously plagiarizing (submitting other people's code or projects as their own without citation), we do what all rigorous institutions of learning should do - we revoke their certifications and ban those people.
This code is running live at freeCodeCamp.org.
Our community also has:
- A forum where you can usually get programming help or project feedback within hours.
- A YouTube channel with free courses on Python, SQL, Android, and a wide variety of other technologies.
- A technical publication with thousands of programming tutorials and articles about mathematics and computer science.
- A Discord server where you can hang out and talk with developers and people who are learning to code.
