One of our more colourful traditions at ZIS is the House system.  Upon enrolment, students join one of four houses, forever associating themselves with a house colour: red, green, blue, and yellow.  Age is no limitation – 3 year olds, 15 year olds, even staff are members of a house team.  The House Challenges range from the predictable to the unfathomable: Sports Days, water challenges, school trivia quizzes – whatever the challenge, students are invited to push their limits and flex their collaborative and leadership muscles.
