Why is a school a secondary group?

A school is considered a secondary group because it is characterized by more formal and impersonal relationships, where individuals come together for a specific purpose, such as education. In a school setting, interactions are often goal-oriented, focusing on academic achievement and social development rather than deep personal connections. Additionally, members of a school are typically there for a limited time, further distinguishing it from primary groups, which are characterized by close, enduring relationships.
