ECAs and ASAs

Primary School

Our Primary School students are offered a wide variety of Extra Curricular Activities (ECA) and After School Activities (ASAs) which allow students to explore their interests or try new activities outside of the school curriculum. ECAs are offered by internal teachers and run on campus, while ASAs are offered by external service providers (please refer to schedule on the ASA website for further details).

ECAs and ASAs are not just about sports. There is an ECA or ASA for every student’s interest at ISS. A high level of interaction with friends is encouraged through a range of activities from craft and computing to coding and photography.

ISS offers ECAs and ASAs ranging from sports like volleyball and football to art courses, Music Club, Science Club and a range of other activities. In addition to other programmes, our students participate in Sports Day and the Swim Gala annually. These events provide opportunities for every student in the school to compete in many different events.

Please note that ECAs are free of charge, while ASAs are paid activities that are run by external service providers.

How are ECAS/ASAs assigned?

We offer equal opportunity for all students to participate in our ECA and ASA programme. We use an online sign up form. We make every effort to ensure that every student is accepted to an ECA/ASA. There are no limits to the number of courses a student may partake in.

High School

The ISS Extra Curricular Activities (ECA) programme is the heart of the Activity component of our Creativity, Activity and Service requirement for all ISS students. Students in the High School have a wide variety of activities to choose from including community service, special interest clubs, varsity sports teams and some students even start their own ECA. ISS participates in the Athletic Conference of Singapore International Schools (ACSIS) league for varsity sports including volleyball, football and many more. Although the High School is located in town and has some space constraints – this has however not limited the students in their ECA choices.
