LTI 1.1 Certification Requirements

LTI 1.1 Certification Requirements


We are in the process of building out support for LTI 1.1 as a Tool Provider, and we are trying to understand what elements of the specification are required in order to obtain certification. In particular, I am interested in knowing if support for the Outcomes service is required in order for us to be certified as being LTI 1.1 compliant. This page (, that outlines the conformance tests that will be run for each version of the LTI standard, suggests that the suite for 1.1 includes testing for the Outcomes service. However, when reading the implementation guide (, the outcomes services all indicate that their implementation is "recommended."

Any guidance you can provide would be most welcome.

Thank you,
