The IMS Comprehensive Learner Record (CLR) specification has been designed to create, transmit, and render an individual's set of achievements, as issued by multiple learning providers, in a machine-readable format that can be curated into verifiable digital records of achievement.
The IMS CLR specification supports interoperability in that CLR publishers and consumers can consistently send, receive, and verify records among conformant systems. The CLR specification describes an information model, service definition, and implementation guide to allow institutions, suppliers, and others to 'extend' the traditional transcript with records and types of information that are typically not found in a traditional transcript, such as competency attainment and co-curricular activities, and to define and facilitate an institution's learner achievements record store for collection of CLRs.
CLR data can be consumed by other schools, institutions, employers, and any other entities that are conformant as CLR consumers. In this machine readable format, CLR data enables granular and expansive discoverability of learning achievements that was not previously possible.
This document is the Candidate Final Release, meaning the technical specification is also in Candidate Final Status. IMS Members are currently working towards successful completion of conformance certification.
IMS strongly encourages its members and the community to provide feedback to continue the evolution and improvement of the CLR standard.

IMS offers a process for testing the conformance of products using the IMS certification test suite. Certification designates passing a set of tests that verify the standard has been implemented correctly and guarantees a product’s interoperability across hundreds of other certified products. The CLR Conformance Certification Guide [CLR-CERT-10] provides details about the testing process, requirements, and how to get started.
Conformance certification is much better than claims of “compliance," since the only way IMS can guarantee interoperability is by obtaining certification for the latest version of the standard. Only products listed in the official IMS Certified Product Directory can claim conformance certification. IMS certification provides the assurance that a solution will integrate securely and seamlessly into an institution's digital learning ecosystem.
In order to become LTI certified a paid IMS membership is necessary. Here's why: 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 IMS community for continuous support for achieving "plug and play" integration. Certification implies ongoing community commitment to resolve problems, revise implementations and retest as need. For that reason, only IMS Contributing Members, Affiliate Members and Learning Tools and Content Alliance members are eligible to apply for conformance certification. Details and benefits of membership are listed here: https://www.imsglobal.org/imsmembership.html.This document is an informative resource in the Document Set of the Comprehensive Learner Record specification [CLR-10]. As such, it does not include any normative requirements. Occurrences in this document of terms such as MAY, MUST, MUST NOT, SHOULD or RECOMMENDED have no impact on the conformance critera for implementors of this specification.
The IMS Certified Product Directory is the official listing of products that have passed IMS Global conformance certification testing. Products that are listed in this directory are guaranteed to meet the IMS standards for which they have passed testing. If you experience an integration issue with a product listed here, IMS will work with the supplier to resolve the problem. If a product is NOT listed here it has either not passed IMS testing or its certification has expired.
The CLR OpenAPI Schema files can be used to develop and implementation of the CLR API.
