The distinction between "co-curricular" and "extra-curricular" lies in their relationship to the formal academic curriculum.

Co-curricular activities are closely aligned with the goals and values of the school's curriculum. They are designed to enhance and enrich the educational experience while aligning with the school's educational philosophy. These activities are often organized or endorsed by the school, and they are seen as an integral part of the holistic development of students. Co-curricular activities contribute to the overall learning objectives of the school and are meant to complement classroom learning. Examples include student clubs, intramural sports, leadership programs, and school events.

Extra-curricular activities, on the other hand, are activities that are conducted outside of the regular academic curriculum and are not directly related to the school's educational goals. While they still offer valuable learning opportunities, they are not an inherent part of the school's core curriculum. Extra-curricular activities are typically student-initiated or organized by external entities. Examples include hobbies pursued outside of school hours, participation in community organizations, and activities that aren't directly connected to the school's educational objectives.
