Hidden curriculum

The hidden curriculum names the lessons a school teaches without ever writing them into a syllabus: the norms, values and expectations students absorb from how a classroom is run rather than from its stated content. Philip W. Jackson coined the term in his 1968 book Life in Classrooms, arguing that schooling works as much as a socialization process as an academic one, and Benson Snyder soon extended the idea at MIT, showing how unstated academic and social rules generate real student anxiety. Later critical educators, including Paulo Freire, Ivan Illich, John Holt and Henry Giroux, argued that the hidden curriculum tends to reproduce existing social class divisions rather than level them, since it quietly rewards the manners, speech and assumptions already familiar to more privileged students. Typical examples include schools teaching obedience and punctuality alongside their formal lessons, unstructured time teaching children how cliques and pecking orders form, and curricula built around unstated heterosexual or neurotypical assumptions that leave other students to work out unwritten rules for themselves.
