Four Houses,
One Community

At The International School of Texas, every student — from Junior Pre-K through Grade 12 — is placed in one of four houses. The Trailblazer House System fosters belonging, teamwork, and school spirit while encouraging students to embody IST’s core values every day.

Students and their siblings remain in their assigned house throughout their entire IST journey, building lasting friendships and traditions that cross grade levels and divisions.

Living Our Values

Houses accumulate points throughout the year by demonstrating the IB Learner Profile attributes and practicing IST’s core values: Respect, Integrity, Confidence, Intellect, and Service. At the end of the year, the house with the most points is awarded the coveted House Cup.


Spirit and Tradition

The House System is woven into many of IST’s most cherished traditions:

  • House-colored shirts worn every Friday
  • Fall food drive competition benefiting Central Texas Food Bank
  • Family gatherings and community events
  • Sports Day house competitions
  • Pep rallies celebrating house pride and camaraderie
