This document specifies requirements for language-learning services. These include any language-learning services that are addressed to language learners themselves as well as to interested parties who are acquiring the services for the benefit of learners. The key features of any such service are that the goals of learning are defined and evaluated, and that it involves interaction with the learner. The instruction may be delivered face-to-face, be mediated by technology or be a blend of both.

In cases where the language-learning services are provided by an organization that delivers products (goods and services) or other learning services in addition to language-learning services, this document only applies to language-learning services.
