LEARNING TOOLS INTEROPERABILITY® 1.3 AND LTI ADVANTAGE ARE TRANSFORMING DIGITAL LEARNING
- Introduction of the 1EdTech 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. Watch the Get to Know LTI Advantage video.

LTI 1.3 optional services:
These 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 1EdTech Contributing, Affiliate, or Learning Tools and Content Alliance member to access these Member Candidate Final draft documents.
- Dynamic Registration 1.0 Public 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.
- Submission Review 1.0 Public 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 Public 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)
- 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.
- Cookie Problems: OIDC Login with LTI Client Side postMessages -- For the LTI launch flow use window postMessages to store and validate state instead of cookies. Please refer to the following 3 documents.

LTI in Brief
The 1EdTech 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.
1EdTech has testing programs that enable products to be certified compliant with specific standards and features of the standards. For technology suppliers, participation in the 1EdTech certification process is the fastest and most cost-effective way to achieve product integrations. For institutions, ensuring that your educational technology tools are 1EdTech certified is the best way to establish a plug-and-play ecosystem, allowing your tools and content to work together seamlessly, giving you more choice, and reducing your total cost of ownership. 1EdTech members have access to expert support to implement the standards prior to completing conformance certification.
