Educational theory categorizes curricula into seven primary types that shape learning experiences in schools: the recommended curriculum (proposed by scholars and policymakers), the written curriculum (formal documents, syllabi, and textbooks), the taught curriculum (what teachers actually deliver in classrooms), the supported curriculum (resources, textbooks, and tech tools), the tested curriculum (assessments and examinations), the learned curriculum (what students actually comprehend and retain), and the hidden curriculum (unspoken social values, norms, and behavioral expectations implicitly conveyed in schools).
