Houston, at the junction of 201 Kinkaid School Drive and San Felipe. Kinkaid introduced uniforms for its lower and middle school students beginning in the early 1960s. Upper school students have never been required to wear uniforms. Beginning in 1970, Kinkaid adopted what was known as an "open enrollment" policy. Beginning in the early 1990s, the campus began a large construction program in an effort to modernize its facilities. A new lower school building was constructed, and the old building was torn down, along with the "little" gym and lower school art and science buildings. A new middle school building was also constructed, and the existing upper school was expanded into the old middle school building. A new auditorium and cafeteria were built, and the remaining campus buildings were renovated. In addition to the physical changes on campus, the fifth grade was moved from lower school to middle school. Current and prior heads of school Jonthan Eades is now serving as the School's sixth head of school. Margaret Hunter Kinkaid, the School's founder, served as the first headmistress. She was a public school teacher before founding The Kinkaid School. Kinkaid left the public school system when she discovered that married women were not as welcome as public school teachers in her school district. Kinkaid was the headmistress of the School from its founding until 1951. Her son William W. Kinkaid was the principal of the upper school. In 1951 both she and her son retired from their duties at Kinkaid. Mrs. Kinkaid was succeeded as head by John H. Cooper, who stayed with the School for over two decades. He initiated annual productions of Gilbert and Sullivan operettas, starting with H. M. S. Pinafore. Cooper helped move the campus from its Richmond location to the current Memorial site. Cooper left to co-found The John Cooper School in Woodlands in 1972. Glenn Ballard was recruited to replace Cooper in 1972. Ballard had previously been headmaster at Dallas' Hockaday School. Ballard retired after 24 years. Donald C. North was recruited to replace Ballard. North had previously been headmaster at North Carolina's Durham Academy, with earlier teaching and administrative stints at Kinkaid, Fort Worth Country Day School, and Dallas' St. Mark's School of Texas. North led Kinkaid from 1996–2013. Andrew D. Martire was appointed Kinkaid’s fifth headmaster in 2013 after having been recruited from being headmaster at Baltimore's Calvert School. The School’s Board
