Richland High School opened in 1961 as the second high school in the Birdville Independent School District. The school was expanded over time to meet the needs of the community, including a major expansion in the late 1980s that added a new main entrance, classroom wing, cafeteria, and administration offices.
A 2006 bond package funded a nearly-complete demolition of the original school. Only the original auditorium, the band hall, and a wing added in the late 1980s (including the library and cafeteria) were retained, while the rest of the structure was demolished and replaced with student parking. A brand-new facility was built in the old student parking area, connected to the remnants of the original structure. The new school opened for the 2009-2010 school year.
During the 2008-2009 school year, Richland High School introduced its first AVID class. The program graduated its first group of seniors in May 2012.
In 2010, the Richland High School Choir performed at the Texas All-State Convention in San Antonio, Texas. This was the second Texas Music Educators Association (TMEA) honor choir that came from Richland.
In 2011, the Richland High School Marching Band merged with the Birdville High School Marching Band and the Haltom High School Marching Band to become the All-Birdville ISD Marching Band; they were one of 13 marching bands to take part in the annual Tournament of Roses parade in Pasedena, California.
On Friday, September 28, 1984, Richland was the site of a school shooting. No students or faculty were killed, though the shooter, Barry Wayne Shaw, a 1981 alumnus of Richland, was charged and convicted in the fatal shooting of a Dallas karate instructor, Jimmy Glen Wilson, on Monday of that week.
