The 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.
The basic steps to getting started with LTI are as follows:
Watch a 5 minute video on the basics of LTI here:
Read and understand the LTI specification documents here: https://www.imsglobal.org/activity/learning-tools-interoperability#LTIpublic
Join 1EdTech as a member https://www.1edtech.org/about/membership
Begin implementing by using the Reference Implementation code library (github repository available to 1EdTech members)
You can test your implementation progress throughout the various stages of development by testing your tool against the hosted Reference Implementation instances here: https://lti-ri.imsglobal.org/
When you are ready to test any or all of your products against the LTI certification test suite, you can self test at any time here: https://www.imsglobal.org/lti-certification-suite
The minimum level of membership for the LTI reference implementation is the Learning Tools and Content Alliance: https://www.1edtech.org/about/membership/supplier
There are also some open source LTI libraries that you might find helpful: https://github.com/IMSGlobal/ltibootcamp
While some specification documents are freely available for adoption, 1EdTech membership offers the ability to become certified, access to early spec drafts, testing/adoption resources, inclusion in the TrustEd App product directory, and other benefits. You can see all of the membership details and benefits here: https://www.1edtech.org/about/membership
1EdTech membership is required in order to become LTI certified and the Learning Tools and Content Alliance is the minimum membership level for these benefits. The cost of the Alliance is minimal and varies depending on organization size or revenues. You can see prices and benefits, as well as join online here: https://www.1edtech.org/about/membership/supplier
Certification testing after implementing is critical to ensuring integrations will work with other tools or platforms. While conformance certification provides a "seal" for passing prescribed tests it is much more than that. It is a commitment by a supplier to the 1EdTech community for ongoing support for achieving "plug and play" integration. Certification implies ongoing community commitment to resolve problems, revise implementations and retest as needed. For that reason, only 1EdTech Contributing Members, Affiliate Members and Learning Tools and Content Alliance members are eligible to apply for conformance certification.
