LTI® v1.3 and LTI Advantage

LTI Advantage Resources Public Documents IMS Member Resources



The new core LTI version 1.3 and a package of high-value services align LTI with industry-best security and provides a clear path forward for existing services and new services to pursue the rich integration available between learning platforms and tools. Here is a quick look at what's new in LTI v1.3:
  • Introduction of the IMS Security Framework specification prescribing improved security based on OAuth2 and JSON Web Tokens
  • Improved documentation and migration guidance to help move the market from the benefits of basic launch to the full suite of LTI possibilities
  • Alignment with the LTI Advantage set of services that enable a fully integrated and innovative digital ecosystem

LTI ADVANTAGE is a package of three essential end-user services that build on LTI v1.3. Together, these standards implement features that support key teaching and learning activities, such as the provisioning of usernames and roles so a tool can intelligently address the learner on launch, and the exchange of assignments from a platform to an assessment tool and the subsequent scores back to a central gradebook.

LTI in Brief

The IMS Learning Tools Interoperability (LTI) standard prescribes a way to easily and securely connect learning applications and tools with platforms like learning management systems (LMS), portals and learning object repositories on your premise or in the cloud, in a secure and standard manner and without the need for expensive custom programming. Using LTI, if you have an interactive assessment application or virtual chemistry lab, it can be securely connected to your LMS with a few clicks. LTI is comprised of a central core and optional services to add optional features and functions. The LTI core establishes a secure connection and confirms the tool’s authenticity while the extensions add features like the exchange of assignment and grade data between an assessment tools and your LMS gradebook.
