2U Partners with CodeSignal to Bring 400+ Hands-On Courses to edX

On September 22, 2026, 2U announced a partnership with CodeSignal to bring more than 400 hands-on, practice-based courses to edX, its global online learning platform, for the first time. The first courses are now live, with the full catalog available on edX by the end of the year. Roughly a third to half of the initial catalog focuses on practical AI skills, including prompt engineering, AI literacy for business roles, ethical AI development, and building AI-powered applications. Skill checks are built into the courses, and CodeSignal's AI tutor Cosmo provides one-on-one guidance and instant feedback.

The partnership shifts the online course model from videos and quizzes toward completing tasks in simulated work environments with verified skills, embedding an AI tutor and skill checks directly into the learning experience. For learners, completing a course can leave verifiable evidence of ability; for employers, the Enterprise Catalog supports building AI and technical fluency at scale. The original text provides no independent research or quantitative results, so actual learning outcomes and the accuracy of skill verification still need follow-up observation. edX learners can practice AI and technical skills in simulated work environments with built-in skill verification and instant feedback from an AI tutor. Organizations can purchase these courses at scale through edX's Enterprise Catalog to build AI and technical fluency across teams.
