In which context is andragogy mainly applied?

Andragogy is a term specifically associated with adult education, emphasizing the unique ways adults learn compared to children. It recognizes that adult learners bring a wealth of life experiences and knowledge that influence their learning process. This concept includes principles such as self-direction, problem-solving, and the importance of relevancy in learning for adults, who often seek knowledge that directly applies to their personal or professional lives.

In contrast, primary and secondary education typically focuses on the instruction of children and adolescents, using pedagogical methods tailored to younger learners who often require more guidance and structure. While vocational training is also relevant to adult learning, it is often considered a subset of adult education rather than the primary context in which andragogy is applied. Thus, the main context for andragogy is indeed adult education, making it the best answer.
