Certifications

认证

freeCodeCamp.org offers several free developer certifications that make up the Full-Stack Developer Curriculum: Responsive Web Design, JavaScript, Front-End Development Libraries, Python, Relational Databases, Back-End Development and APIs. Each of these certifications involves completing interactive lessons, workshops, labs, reviews, and quizzes. Throughout the certification, you’ll need to complete 5 required projects to qualify for the exam. Once you pass the exam, then you can claim the certification.

freeCodeCamp.org 提供多项免费的开发者认证，构成了全栈开发课程：响应式网页设计、JavaScript、前端开发库、Python、关系型数据库、后端开发与 API。每一项认证都包含交互式课程、研讨会、实验、复习和测验。在认证过程中，你需要完成 5 个必修项目才有资格参加考试。通过考试后，你即可领取认证。

freeCodeCamp.org also offers free language certifications designed around internationally recognized proficiency levels: A2 English for Developers (Beta), B1 English for Developers (Beta), A1 Professional Spanish (Beta), A1 Professional Chinese (Beta). Each of these certifications is organized into modules, with sections for warm-ups, lessons, practice exercises, review pages, and quizzes to ensure you fully grasp the material before progressing to the next module. You’ll need to complete all of the quizzes in order to qualify for the exam at the end of the certification.

freeCodeCamp.org 还提供围绕国际公认熟练度等级设计的免费语言认证：A2 开发者英语（测试版）、B1 开发者英语（测试版）、A1 专业西班牙语（测试版）、A1 专业中文（测试版）。这些认证均按模块组织，包含热身、课程、练习、复习页面和测验，以确保你在进入下一个模块前完全掌握所学内容。你需要完成所有测验，才有资格参加认证结束时的考试。

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.

一旦你获得了认证，它将永久属于你。你可以随时将其链接到你的 LinkedIn 或简历中。当潜在雇主或自由职业客户点击该链接时，他们将看到专属于你的已验证认证。唯一的例外是我们发现违反了我们的学术诚信政策。当我们发现明确的剽窃行为（在未注明引用的情况下提交他人的代码或项目作为自己的作品）时，我们会采取所有严谨教育机构应有的做法——撤销他们的认证并封禁这些人。

In addition, to help prepare for job interviews, freeCodeCamp.org includes The Odin Project (freeCodeCamp Remix), Coding Interview Prep, Project Euler, and Rosetta Code. A free, professional Foundational C# with Microsoft Certification is also available.
