The Post Oak School

The Post Oak School is a private Montessori K-12 school with two campuses in Greater Houston. The preschool through elementary location is the Bissonnet Campus in Bellaire, Texas while the middle-high school is in the Museum District of Houston.

Founded in 1963, the school is a non-profit corporation. It is accredited by the Association Montessori Internationale (AMI) and the Independent Schools Association of the Southwest (ISAS). The school serves approximately 600 students, from 14 months through high school. The classroom levels are Infant Community, Primary, Lower Elementary, Upper Elementary, Middle School, and High School. Each level consists of children in three-year age ranges (apart from middle school which has a two-year age range, and high school consisting of a four-year range).

After the 1983 closure of Gordon Elementary School, a Houston Independent School District public school facility, as a neighborhood school, Gordon temporarily housed The Post Oak School.

K-8 campus
The K-8 campus in Bellaire had, in 2010, 3.5 acre of space. It began using the permanent Bellaire campus circa 1987.

In 2013 the school received a permit to expand from the Bellaire City Government.

Circa 2010 some residents in the nearby area complained about parking issues caused by traffic to and from the Post Oak School Bellaire campus and the adjacent Episcopal High School.
