CCA meaning in Academic & Science ?

In Singapore, a co-curricular activity (CCA), previously known as an extracurricular activity (ECA), is a non-academic activity that all students must undertake as part of their education. Introduced by the Ministry of Education (MOE), CCAs are strongly encouraged in the primary level but compulsory in secondary education. Students can choose from 4 categories: Clubs and societies, Physical sports, Uniformed groups, and Visual and performing arts They may also start their own activities with the school’s approval.
