of 2013, more than 230 schools required their students to wear school uniforms or "standardized dress." As of 2006, over twenty high schools require their students to wear school uniforms or "standardized dress." Of them, one, Lamar High School, had a White plurality. Nine Houston ISD high schools did not require students to wear uniforms or standardized dress. Four of them had White students as the largest group of students. In 1991 Key Middle School was the first school in HISD to introduce school uniforms. At the time, they were not required, but encouraged. Around the early 1990s the district began a trend of more localized management, so local schools set their own dress code policies.

In meetings it had been proposed as a new location for the High School for the Performing and Visual Arts. Houston ISD's administration building, which opened in 1969 and served in that capacity from July of that year to March 2006 was the Hattie Mae White Administration Building, at 3830 Richmond Avenue.
