School Notes

  • The Post Oak School has operated continuously since 1963 and is a non-profit corporation. With a faculty and staff of over 100, we provide a culturally diverse student population with a comprehensive education founded on AMI Montessori principles. The Post Oak School is fully accredited by the Independent Schools Association of the Southwest (ISAS) and, at the high school level, by the International Baccalaureate Organization (IBO). Our core curriculum is enhanced by specialized offerings (such as art and theater), extracurricular programs, interscholastic sports, travel opportunities, and internships with partner institutions in the Museum District and Texas Medical Center. Fundamental to the Montessori idea is the belief that a person`s life work should have significance both for the individual and for society. To that end, The Post Oak School has cultivated a culture of active, regular community involvement among both students, families, and staff. Our students perform community service as part of their curriculum, our families participate in service opportunities, and we as a school contribute to the academic community by training teachers, organizing and chairing educational conferences, and hosting respected speakers on a variety of topics.

School Reviews

World-class Montessori education. We have been members of the Post Oak community for six years. We enrolled our children in part because of my own positive experiences as a Post Oak student in the 1980s. From my own experience, one skill that I unequivocally attribute to Post Oak is an endless curiosity about the world and my place in it; a love of learning for the sake of learning. Post Oak provides the perfect foundation for the development of a well-rounded, intellectually-curious, self-reliant child. We love the faculty and their dedication to empowering our children as individuals for future success not just as students, but as contributing members of society.

How Diverse Are Private Schools?
Decades ago private schools could have been accused of being elitist. You had to have money to attend. The student populations were fairly homogeneous. Fortunately that has changed.
