Peer education is an educational approach in which individuals from the same or similar social group (e.g., age, community, role, or lived experience) provide structured information, skills support, and behavior-oriented guidance to one another [1][2][3][4]. It is used to facilitate learning through credibility, shared context, and social influence, especially in areas such as health promotion, prevention, and youth development [1][2]. Peer education is characterized by planned training of peer educators, defined learning objectives, interactive communication, and ongoing supervision or quality assurance. In research and practice, the term denotes organized peer-led educational interventions, not casual advice exchanged among peers without instructional design and evaluation.
