About the International School of Texas
In September 2013, The International School of Texas was founded by a group of 13 brave parents who shared a common vision of an exceptional education for their children: one that is marked by free thought, equal opportunity, and the development of our core values of Respect, Integrity, Confidence, Intellect, and Service. Over the years that passed, IST quickly outgrew its initial location and moved into a newly completed campus west of Austin. In August of 2024, we opened the doors to our new, state-of-the-art campus in the rolling hills of Bee Cave, and we launched our first cohort of high school students.
Since 2017, IST has been an authorized International Baccalaureate World School. IB World Schools share a common philosophy—a commitment to high-quality, challenging, international education—that we believe is important for our students.
