ISO 29991:2014规定了正规教育以外的语言学习服务要求。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。 有兴趣使用ISO 29991:2014的实体将包括各种类型和规模的语言学习服务提供商，以及语言学习服务提供商的协会或联盟。 如果语言学习服务由除语言学习服务外提供产品（商品和服务）或其他学习服务的组织提供，ISO 29991:2014仅适用于语言学习服务。 ISO 29991:2014并不是专门针对将语言学习作为正式教育体系一部分的学校、学院和大学，但可能对他们有用，作为反思和自我评估的工具。

ISO 29991:2014 specifies requirements for language learning services outside formal education. These include any language learning services that are addressed to language learners themselves, as well as to interested parties that 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 can be delivered face-to-face or mediated by technology, or it can be a blend of both. Entities interested in using ISO 29991:2014 will include language learning service providers of all kinds and sizes, as well as associations or consortia of language learning service providers. 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, ISO 29991:2014 only applies to language learning services. ISO 29991:2014 is not specifically aimed at schools, colleges and universities which provide language learning as part of a formal educational system but may be useful to them as a tool for reflection and self-evaluation.
