SHSID has many school clubs, such as Live 2 Drama, Eco Cap, MUN, WSC, USAD, Biology Workshop, among others. These clubs have organized school activities such as poetry competitions, sports competitions, stargazing nights, math and science competitions, etc. Almost every student participates in several school clubs to satisfy their individual interests and curiosities, and during the lunch break the classrooms are often occupied with club meetings. The walls of the school building also give evidence to the great number of clubs, with wallpapers of all colors advertising club events.
