Learning Tools Interoperability (LTI) is a standard created by the IMS Global Learning Consortium.
Contents
Its primary purpose is to connect learning systems such as a learning management system (LMS) with external service tools in a standard way across learning systems. The standard describes the connecting system as an LTI Tool Consumer and the connected tool as an LTI Tool Provider.
Terminology
LTI Consumer: This is the service that is consuming the tool. Typically this is a Learning Management System (LMS) or user portal. The LTI Consumer provides user information and context to the LTI Tool Provider. Additionally the LTI Consumer provides authentication vouching for the user to the LTI Tool Provider.
LTI Tool Provider: This is the service providing the service to the LTI Consumer. This can be on-premises software or a service that is hosted outside the LTI Consumer.
Use
LTI is a primary means by which course content and learning technology functionality is delivered from content providers to students via their institutional LMS interface or portal. It delivers courseware as a service from most large educational content providers, including Pearson and McGraw Hill and is an educational technology distribution and implementation tool in widespread use. Popular LMS software such as ManageBac, D2L, Canvas, Blackboard, and Moodle employ LTI integration to supply student access to third-party software.
