The Post Oak School

Founded in 1963, The Post Oak School now enrolls nearly 450 students from 14 months through high school on two campuses.  The school originally served children between the ages of 3 and 6 in a one-room schoolhouse located in the Briar Grove section of Houston.  According to the school, Post Oak is the oldest Montessori school in the Southwest United States.

Location and Facilities

The main campus of The Post Oak School is located in the city of Bellaire, a small city within the metropolitan area of Houston, Texas.  The campus occupies a 3.5-acre lot located at the intersection of Bissonnet Street and Avenue B and is easily accessible from the West Loop, US-59, and the Westpark Tollway.  Built in 1986, the 55,000 square foot building includes 19 classrooms, a library, a music studio, an art studio, a gym, an outdoor playground, a commons area, a recreation field, a basketball court, and gardens.


The Post Oak High School campus is located in the Houston Museum District just off US-59, giving students immediate access to the resources of the nearby museums and cultural institutions. The school building, which serves as the hub of this extended campus, features an open floor plan and features a design lab, a science lab, a presentation area, small group work areas, and a reception area.

Academic Tracks and Curriculum

The Post Oak School utilizes the Montessori educational method, which was developed by an Italian physician, Maria Montessori, and serves children from birth to the age of eighteen.  The Montessori Method emphasizes independence and freedom within limits and takes into account the variation of behavioral tendencies of children of different ages.  It involves mixed age classrooms, student choice of activity, and uninterrupted periods of work.  The school emphasizes active, hands-on learning, meaningful work, self-direction, the development of personal interests, and the opportunity to cultivate real-world social skills through peer teaching and collaborative learning.


The high school is an International Baccalaureate candidate school where students study English Language Arts, foreign language, history and the humanities, science, math, fine arts, and physical education.  Twice each year, students participate in single, intensive multi-week classes that are collaboratively selected and designed by students and faculty, such as psychology or entrepreneurship and design.  Students also complete a community service requirement and a capstone research project.


High school students use the resources of the Houston Museum District, Texas Medical Center, and local colleges and universities to open opportunities for long-term internships tailored to their interests and to extend their classroom learning.  Students have visual arts classes at the Glassell Junior School, theater classes at Main Street Theater, and physical fitness classes at the Gibbs Recreation Center at Rice University.  Students conduct research in the field around the Museum District and do library-based research at the Fondren Library at Rice University and at the Doherty Library at the University of St. Thomas.


Special Needs

The Post Oak School believes that “in a fundamental way, all children have special needs.”  The Post Oak School aims to respond to each child as an individual, to help each child identify personal interests and to develop skills.  For example, one child may be ready to do far more than what a narrowly-defined curriculum might prescribe, another child may need to repeat an activity before understanding, and some children have diagnosed learning differences.  In many cases Post Oak can meet those needs in the classroom; in other cases, we do not have the resources or the expertise to do so.  In either case, the school will make that determination with parents and in consultation with outside experts.


Foreign Languages

Children learn Spanish language and culture from the earliest ages at Post Oak.  In the elementary years, Spanish instruction includes formal lessons.  Younger children concentrate on basic vocabulary and conversation, while older students learn Spanish grammar, verb conjugations, and written Spanish.  High school students choose to study Spanish or Mandarin Chinese.



Students at Post Oak work in various media of the visual arts.  For younger children, artistic expression is always available in their classroom as a choice of activity.  Once children enter the elementary years, formal classes introduce a variety of artistic media, including drawing, painting, and sculpting.  Elementary and middle school classes design sets for classroom theatrical productions and produce models and illustrations to accompany academic work.  High school students walk to the nearby Glassell Junior School for their visual art classes.


Students engage in music study and performance from their early years at Post Oak.  Elementary, middle, and high school students continue performance as well as music appreciation and music history.


Elementary, middle, and high school students study theater as appropriate to their ages with a focus on performance and performance support work.  High school students work with the Main Street Theater for their visual arts classes and performances.



The Post Oak School offers students technology that is matched to their stage of development.  Pre-elementary students utilize common hand tools and other manipulative learning materials, but no electronic technology.  Young elementary students use computers in the school library for research, and by the upper elementary level (grades 4-6), there are desktop computers in the classroom.  Middle school students use laptop computers in class, and each student is issued an e-reader.  The high school is an iPad environment, and students use the device as an e-reader, for various apps that have academic applications, and to produce work in writing and other media.  High school students explicitly learn how to manage e-mail, files, calendars, written work, and the other elements of their electronic, online lives.


Extracurricular Activities

The Post Oak School offers optional after-school enrichment classes, including art, choir, dance, Chinese, Spanish, and chess classes.  A variety of clubs are also offered for student participation, including cheer squad, Montessori Model UN, stamp collecting, a running club, and intramural sports.



Post Oak School offers interscholastic competition at the middle school level (grades 7-8) in the following sports: cross-country, volleyball, soccer, and basketball.  Upper elementary students (grades 4-6) can participate in intramural sports afterschool.  In the spring, a post-season flag football team is offered for students in both elementary and middle school.


At the high school level, students participate in outside clubs because the athletics department is currently in development.  Physical education classes utilize facilities at Rice University and enable students to explore a range of fitness options including ultimate Frisbee, yoga, basketball, track, and volleyball.


Parent Involvement

The Post Oak School invites parents into a partnership in service to their child.  In terms of the day-to-day life of the school, there are many opportunities for involvement: from service on the board of trustees to cooking with small groups of children; from sharing your professional expertise with classes to helping chaperone field trips; from gardening with children to working with parent committees to organize community events.
