The Awty School was founded by Kathleen "Kay" Awty in 1956 as a pre-school. The incorporation of an Upper School in 1975 changed the school into a college preparatory school which merged with the French School of Houston and became The Awty International School in 1984. With a total enrollment of over 1,700 students, Awty is currently the largest private school in the city of Houston and the second largest international school in the United States.

Enrollment has increased from 750 to more than 1,700 over the last 20 years. Today, the school is located on a 15-acre campus in central Houston. Premises include 120 classrooms, science laboratories, art rooms, computer laboratories, libraries, a cafeteria, two covered basketball/volleyball courts, a state-of-the-art athletics center, two soccer fields, and two gymnasiums. The main campus has seen several renovations through the years.  Awty's original preschool facility was completed in 1990, a secondary school science building in 1991, additional preschool classrooms in 1995, and a secondary school building including a computer center, foreign language laboratories and a new library in 1996. Construction was then completed on the Performing Arts and Athletic Center (PAAC). A classroom wing opened in Fall 1999 and the Lower School building opened in 2003. The school opened Awty Field, a state-of-the-art athletics stadium, in 2008. The facility includes a 1,400-seat stadium, press box, soccer field, eight-lane track and field event facilities, four tennis courts, concession stand, locker rooms, maintenance facility, storage facility, and parking.

In June 2012, the school opened the Levant Foundation Building, a new classroom building. The three-story, 65,000 square foot facility includes 33 educational classrooms, two art classrooms, one digital photo room, a new dining hall for the entire student body, new administrative offices, and additional meeting rooms. This LEED certified building serves as the front door to Awty’s campus. In addition to this new classroom building, the school also opened a five-story parking garage in October 2012. This 174,000 square foot facility offers approximately 440 parking spaces, houses the Maintenance and Facilities Department, and facilitates a reorganized, safer carpool.

In April 2014, the school opened the Lower School expansion. This addition added almost 15,000 square feet to the existing Lower School Building. It consists of nine classrooms, a large media facility, a computer lab, a drama classroom, an art room filled with natural light, a teacher workroom, and a medical clinic. Adjacent to the Lower School addition is a large playground that features shade structures, playground equipment, seating areas, and rubber fall surfaces.

In 2017, Awty opened a second campus, the Early Learning Campus, located at 1110 North Post Oak within walking distance of the main campus. This second 5-acre campus for PK3/PS, PK4/MS, Kinder/GS, and 1st grade/CP students features 26 classrooms, dedicated indoor spaces for art, music, dining, after-school program, and technology, as well as a full gym. Outdoors, the facility features two playgrounds, learning gardens, and three decks for class activities.

In June 2021, the school began construction of a new Campus Center, located at the heart of the main campus. These new facilities will support our students, their teachers, and the ever-changing educational and professional environments they will enter. It has been designed and refined to create a space allowing students to build community, develop 21st century skills, and engage deeply in science, technology, engineering, arts, and math (STEAM). Construction will occur in two phases. In Phase I, the science wing, computer wing, and Secondary library will be removed. Those buildings will be replaced by a new three-story building providing state-of-the-art learning facilities, including a future-oriented library, science labs, and collaborative classrooms, along with new dining halls and an auditorium. Through thoughtful design, we also will be increasing the available green space on campus. In Phase II, to be built shortly thereafter, the two-story building, Fine Arts Recital Hall, staff cafeteria, and cottage will come down to make way for a makerspace and tech classrooms, as well as additional classrooms and collaborative workspaces.
