    The Post Oak School has operated continuously since 1963 and is a non-profit corporation. With a faculty and staff of over 80, we provide a culturally diverse student population with a comprehensive Montessori education steeped in AMI Heritage. 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 augmented by specialized offerings (such as art and theater); extracurricular programs; and interscholastic sports. Post Oak serves students from Young Children's Community through High School. The High School opened in the fall of 2012 and will add a grade each year over the following three years.

    Fundamental to the Montessori idea is the belief that one’s lifework 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 and staff. Our students perform community service as part of their curriculum, 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.
