本文件规定了语言学习服务的要求。这些服务包括针对语言学习者本身以及为学习者的利益而获取服务的相关方的任何语言学习服务。任何此类服务的关键特征都是定义和评估学习目标，并涉及与学习者的互动。教学可以面对面进行，也可以通过技术进行调解，或者两者兼而有之。 如果语言学习服务由除语言学习服务外还提供产品（商品和服务）或其他学习服务的组织提供，本文件仅适用于语言学习服务。

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.
