Every course on this page gives a certificate, badge or statement of completion at no cost when you finish it. Providers include freeCodeCamp, Kaggle, Microsoft Learn, Cisco Networking Academy, HubSpot Academy, Google Skillshop and IBM SkillsBuild.
With a free certificate the course and the credential cost nothing. With a paid certificate the lessons are free but the verified certificate (and often graded work) costs money, as on edX or NPTEL exams. We label every course with one of three tags: free certificate, paid certificate or no certificate.
They show initiative and the topics you covered, and certificates from well-known issuers such as Google, Microsoft, Cisco or HubSpot are recognised by many employers for entry-level roles. For technical jobs, projects you can show usually count for more than any certificate.
