If you work in edtech, you probably have heard about the LTI standard and asked if your platform supports LTI® integration. In this article, we'll talk about what LTI integration means - with respect to K12 and higher education - and what you should know about the standard.

What is LTI?

The Learning Tools Interoperability® (LTI) standard is a series of standards published by the IMS Global Learning Consortium® that provide a method for applications to integrate with learning platforms. For this article, the learning platforms we are discussing are the learning management systems that are primarily used by K12 and higher education institutions.

What is LTI integration?

While not an officially defined term, an LTI integration usually refers to an application that can connect to an LTI-compliant platform through the LTI standard. Connecting to a platform via LTI can allow your app to integrate with the platform - usually a learning management system. The level of integration depends on the app and the version of LTI that it complies with. Typically, LTI-integrated apps can automatically sign in users who launch an LTI app from a course in their LMS. LTI apps may also read user profiles (e.g. see if a user is a teacher or a student) and send grades back to the user's gradebook.

What are the different versions of LTI?

The most recent version of LTI that is supported is LTI 1.3 with LTI Advantage services. LTI 1.3 is the security framework for LTI-apps and the LTI Advantage services provide additional integrated functionality. Platforms that support all three public LTI Advantage services - Names and Roles Provisioning, Assignment and Grade Services, and Deep Linking - are deemed LTI Advantage Complete. LTI v1.3 is an evolution from LTI v1.0 and LTI v1.1, both of which are still widely used.

Who supports LTI?

Below is a list of major learning management systems and the most recent version of LTI that they support.

Notably absent from this list is Google Classroom and Microsoft Teams. Google does have an Assignments app that allows teachers to create self-made assessments that are LTI v1.1 compliant. Additionally, Microsoft will soon be releasing LTI apps for Canvas and Blackboard Learn Ultra that allow end-users to integrate OneDrive, Team Meetings, and Class Teams with their existing LMS. However, none of these methods actually support using an LTI-compliant app within the native Google Classroom or Microsoft Teams platforms.
