Learning Tools Interoperability


Learning Tools Interoperability is an education technology specification developed by the IMS Global Learning Consortium. It specifies a method for a learning system to invoke and to communicate with external systems. In the current version of the specification, v1.3, this is done using OAuth2, OpenID Connect, and JSON Web Tokens. For example, a Learning Management System may use LTI to host course content and tools provided by external, third-party systems on a web site, without requiring a learner to log in separately on the external systems, with information about the learner and the learning context shared by the LMS with the external systems.

History

LTI has been adopted by many large educational content providers, including Pearson and McGraw Hill.
Popular Learning Management Systems, such as D2L Brightspace, Instructure Canvas, Blackboard, BenchPrep, LAMS, Sakai, Moodle, and Open edX also support LTI.
