Competency levels refer to the different stages of skill and knowledge that individuals possess in a specific area. These levels help to categorize abilities, ranging from basic understanding to advanced expertise. Organizations often use competency levels to assess employee performance and identify areas for development. In many fields, such as education and professional training, competency levels provide a framework for setting goals and measuring progress. For example, in language learning, students may progress from beginner to intermediate and then to advanced levels, allowing instructors to tailor their teaching methods to meet individual needs.
