In 1985, the Sishya Parent-Teacher Association was established, and by 1989 had raised enough money for the creation of another block, and an auditorium.

It takes place over two days, and students from other schools are invited to participate in a variety of events, in the fields of Dance, Music, Art, and Creative Writing.

Over 900 delegates from schools all over the country, and even abroad take part in the 3-day event, organized, and hosted by the students.

Multiple stalls, events, sideshows and games are on offer, including a large raffle draw with a multitude of prizes.

[9] The Interact club of Sishya, associated with Rotary International, was started in order to motivate its students to engage in charitable work.

It consists of students from the senior school who conduct various fundraising events, the proceeds from which go towards the supplying less fortunate with essential goods.
