What are activities and programs called that enhance and complement classroom learning?

Co-curricular activities are specifically designed to enhance and complement the formal curriculum taught in classrooms. These activities take place alongside the academic programs and often include clubs, sports, music, drama, and other student organizations. They provide students with opportunities to apply what they've learned in school in a practical context, helping to develop skills such as teamwork, leadership, and time management.

While extracurricular programs may include a wider range of activities that occur outside of the traditional classroom environment, they do not necessarily align directly with curriculum enhancement. Supplemental courses typically offer additional academic instruction rather than directly supporting existing classroom learning. Enrichment programs often refer to advanced learning opportunities, but they do not explicitly imply the simultaneous complement to the regular curriculum as co-curricular activities do. Thus, co-curricular activities are the most fitting term for those that work in tandem with classroom learning.
