The Extra-curricular Activities (ECA) Programme at UISG is designed to allow students to pursue their interests, fostering independence and creativity. With over 160 activities available throughout the year, students from Years 1 to 12 can choose from various options, including sports, performing arts, virtual design, STEAM, academics, and community engagements/initiatives. The Activities program allows students to explore their interests and engage in exciting activities that contribute to their well-rounded education at UISG. 

为这些群体提供的 ECA 以探索、创造和非竞争性环境为重点，以促进对所有学生的包容。这种方法鼓励学生积极参与各种活动，让他们发现自己独特的才能和兴趣。每节课前都会发布一份详细的活动目录，提供一份全面的活动清单。.

Secondary students are offered a wide range of activities catering to diverse interests. These activities include service opportunities to empower students to impact broader communities positively. Secondary students can select from staff-led, external providers, or student-led activities.
