The correct answer is hidden curriculum.
Hidden curriculum refers to unintentional learning and knowledge that students gain from being part of their school. For instance, a student might learn how to be a good team player, cultivate a good work ethic, wait for their turn, good behavior, manners and conduct at school, even though it is not explicitly or formally taught to them. Furthermore, through hidden curriculum children learn norms, values and beliefs dominant in the society they live in.
