The school has a wide spectrum of co-curricular activities, ranging from board games like Chess; to athletic sports such as Table tennis, Volley ball, Basketball, Swimming and the field.

Additionally, the students also take part in an annual Olympic style competitive event referred to as the Student Convention. This is a momentous event that draws participants from A.C.E schools in Uganda to take part in competitive activities that include sports, music, drama, field events, poetry and academic exhibitions in Sciences and the Arts.

We also engage interested students in a Holiday Life Skills Program, which draws participants from other schools as well.

The school is keen to ensure that a child grows academically while they also discover and develop their non academic interests and God given talents.
A wholistic education is the enduring goal of education at GCSI.
