Portrait of a Graduate
Portrait of a Graduate
A model of success

At The International School of Texas, our Portrait of a Graduate is grounded in the International Baccalaureate Learner Profile and shaped by our mission to develop knowledgeable, compassionate, and globally minded students. Through the IB continuum and Diploma Programme, students cultivate the self-knowledge, character, and skills needed to thrive in an interconnected world. IST graduates emerge as servant leaders who use their strengths to serve others, community builders who foster meaningful relationships, global citizens who embrace diverse perspectives and cultures, and classically liberal thinkers who pursue truth, think critically, and form well-reasoned conclusions. As service-oriented problem solvers, they are prepared to lead lives of purpose, impact, and lifelong learning.
