The the core LTI® Advantage specification from the IMS Global Learning Consortium® is built on the LTI v1.3 security framework and contains three different services:

  • Names and Roles Provisioning Services
  • Assignment and Grades Services
  • Deep Linking

For more information about LTI 1.3 and the LTI Advantage services, please see our article on this topic.

In addition to the three services, LTI Advantage was designed to allow additional services to be implemented in the future. As of June 2021, the IMS Learning Global Consortium has introduced drafts of several optional services. Most of these services are not yet public and you must be a member of IMS Global Learning Consortium in order to access their documentation. Below are the optional services that are under consideration.


Proctoring Service

Providing a way to allow educators to proctor exams has always been challenging for online learning. Thus, the Proctoring Service was developed to provide a standard way for LTI apps to allow for the proctoring of assessments. The Proctoring Service can also support webcam/microphone interactions and screen sharing. As of June 2021, the proctoring service is the only optional service that has had its specification released to the public.

Submission Review

The Submission Review service will allow for a teacher to student to directly launch into the LTI tool from the gradebook of the learning management system. This launch can take the user directly to the associated submission in the application for the user to review.

Caliper Analytics® Connector

The Caliper Analytics Connector service will allow LTI apps to report a user's activities during a single session, regardless of if the interactions occurred in the app or in the LMS. These activities are defined by Caliper profiles and are tracked through the Sensor API™.

Course Group Service

Many learning management systems allow for the creation of groups within courses. These groups will contain student enrollments that are subsets of the total enrollments for a given course. The Course Group Service allows LTI tools to retrieve these groups and enrollments.

Dynamic Registration

To add an LTI Advantage tool into an LMS, an administrator or educator typically must fill out several fields into the platform's LTI registration form. This manual process is error-prone and can be confusing to configure if the LTI app does not provide proper instructions.

The Dynamic Registration service is a standard to allow LTI Advantage tools to fully register through one URL. This is intended to simply the LTI registration process and to make LTI tools easier to manage. The Dynamic Registration service is designed to work with LMSs and apps that support OpenID Connect and OAuth 2.0 registration workflows.

Data Privacy Launch

With more data privacy laws coming into force, it's important for EdTech apps to be able to handle their legal requirements. At the forefront of these data privacy laws is the European Union's GDPR.

The Data Privacy Launch service is designed to standardize the process of handling GDPR requests in LTI tools. The service will help administrators manage their data privacy requests. This service is not yet finalized, even for members of the IMS Global Learning Consortium.


If you have questions about LMS interoperability, we'd love to chat with you! The Edlink API and platform can help integrate your app with nearly all of the major learning management systems, including Canvas, Schoology, Google Classroom, and Microsoft Teams. We work with several educational publishers and EdTech developers to enhance the functionality of their integrations and to allow them to easily bring on new schools, no matter which platform their clients use.

If you want to learn more about Edlink, please shoot us a message at accounts@ed.link or leave us a note at our support page.
