IMS LTI® 1.3 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 1.3:
  • 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 1.3. 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 1.3 and LTI Advantage Reference Implementation

  • Reference Implementation (RI): IMS members can now test your product(s) when implementing LTI 1.3 and LTI Advantage using the hosted Platform and Tool with the full set of services and messages. The Reference Implementation source code (written in Ruby) is also available to IMS Contributing Members, Affiliates, and Learning and Tools Content Alliance members to use as a starting point to implement LTI 1.3 and the LTI Advantage services. Contact Us if you would like access to the code repository.
  • LTI Member Roundtable: meeting recordings and resources.
  • LTI Advantage Certification FAQ

LTI 1.3 new optional services:
These new optional services work within the LTI 1.3 and LTI Advantage framework to solve specific use cases or business needs. Currently, these new services are not included in LTI Advantage. You must be an IMS Contributing, Affiliate, or Learning Tools and Content Alliance member to access these Member Candidate Final draft documents.

  • Submission Review 1.0 Member Candidate Final -- Provides a standard way for an instructor or student to launch back from a platform's gradebook to the tool where the interaction took place to display the learner's submission for a particular line item.
  • Caliper Analytics Connector 1.0 Member Candidate Final -- Provides a standard way for enabling a tool to report back a user's activities and have those associated with a single user session without regard to whether they occurred within the platform or the tool.
  • Course Group Service 1.0 Member Candidate Final -- Communicates to the tool the groups available in the course and their respective enrollment.
  • Proctoring Service 1.0 Public Candidate Final -- For proctored testing, a test delivery or assessment management system can launch from a platform to a proctoring service that allows a test to be proctored. (Learn more here: LTI Proctoring Service)
  • Dynamic Registration 1.0 Member Candidate Final -- Defines a way to automate the exchange of registration information between platforms and tools that use the OpenId Connect and oAuth 2 registration flows, allowing platform administrators to automate tool registrations and avoid tedious and possibly error prone manual configuration while remaining in control of granting or denying tools access to the platform.
  • Data Privacy Launch 1.0 Member Base Document -- Allows LTI-enabled tools to assist administrative users in managing and executing requests related to data privacy.

Please note that support for the earliest versions of LTI (v1.0, v1.0.1) is no longer offered by platforms, nor does IMS offer certification testing. IMS encourages all tools and platforms to implement the latest version of LTI (v1.3 and Advantage). Certification testing for other versions of LTI (v1.1.x, 1.2, and 2.0) is ending June 2021, more details here.


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.
