An extracurricular activity (ECA) or extra academic activity (EAA) or cultural activities is an activity, performed by students, that falls outside the realm of the normal curriculum of school, college or university education. Such activities are generally voluntary (as opposed to mandatory), social, philanthropic, and often involve others of the same age. Students and staff direct these activities under faculty sponsorship, although student-led initiatives, such as independent newspapers, are very common. However, sometimes the school principals and teachers also bring in these activities in the school among the students.

In education, a curriculum is broadly defined as the totality of student experiences that occur in the educational process. The term often refers specifically to a planned sequence of instruction, or to a view of the student's experiences in terms of the educator's or school's instructional goals. A curriculum may incorporate the planned interaction of pupils with instructional content, materials, resources, and processes for evaluating the attainment of educational objectives. Curricula are split into several categories: the explicit, the implicit, the excluded, and the extracurricular.
