Learning Tools Interoperability (LTI) is a standard developed by 1EdTech formerly known as IMS Global Learning Consortium at the time of creation. It enables seamless integration between learning systems and external systems.[1] In its current version, v1.3, this is done using OAuth2, OpenID Connect, and JSON Web Tokens. For example, a Learning Management System (LMS) may use LTI to host course content and tools provided by external or third-party systems on a website without requiring a learner to log in separately on the external systems. The LTI will also share learner information and the learning context shared by the LMS with the external systems.

A software application for the administration, documentation, tracking, reporting, automation, and delivery of educational courses, training programs, materials or learning and development programs.[1] The learning management system concept emerged directly from e-Learning. Learning management systems make up the largest segment of the learning system market. The first introduction of the LMS was in the late 1990s.[2] LMSs have been adopted by almost all higher education institutions in the English-speaking world.[3] Learning management systems have faced a massive growth in usage due to the emphasis on remote learning during the COVID-19 pandemic.[4]
