Learning Tools Interoperability® Background
Learning Tools Interoperability® (LTI®) is a specification developed by IMS Global Learning Consortium. The principal concept of LTI is to establish a standard way of integrating rich learning applications (often remotely hosted and provided through third-party services) with platforms like learning management systems, portals, learning object repositories, or other educational environments. In LTI these learning applications are called Tools (delivered by Tool Providers) and the LMS, or platforms, are called Tool Consumers.
The basic use case behind the development of the LTI specification is to allow the seamless connection of web-based, externally hosted applications and content, or tools (from simple communication applications like chat, to domain-specific learning environments for complex subjects like math or science) to platforms that present them to users. In other words, if you have an interactive assessment application or virtual chemistry lab, it can be securely connected to an educational platform in a standard way without having to develop and maintain custom integrations for each platform.
IMS Global has testing programs that enable products to be certified compliant with specific standards and features of the standards. For technology suppliers, participation in the IMS Global certification process is the fastest and most cost-effective way to achieve product integrations. For institutions, ensuring that your educational technology tools are IMS Global 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. IMS Global members have access to expert support to implement the standards prior to completing conformance certification. Learn more to begin taking advantage of the benefits of certification.
