The district has 14 elementary schools (K-5), 5 junior high schools (6-8), 4 high schools (9-12), a career center, and two alternative centers for education. The district serves all of Baytown, Highlands, Coady, McNair, outlying areas of East Harris County, and a small portion of West Chambers County. The two local high schools, Robert E. Lee (opened in 1920's) and Ross S. Sterling (opened in 1967) have long had a friendly rivalry between them. Lee High School has the unique distinction of having two campuses as a result of overcrowding.
Following several years of research and debate, voters passed a $120 million bond referendum in 2005 to improve present facilities, replace several existing schools and build new ones. Included in this package is a third high school (which was included in a 1999 referendum, but never materialized) named Goose Creek Memorial that opened in Fall 2008. Additionally, Victoria Walker Elementary was opened in fall 2007, with plans for a 16th elementary to be drawn. Both new schools are situated in the north area of Baytown which has seen the most growth in recent years. Highlands Junior High and Bowie Elementary were replaced under the bond program. After the opening of Goose Creek Memorial, Lee High School will be reformated to a smaller campus and the auxiliary campus will be converted to its original purpose as an alternative educational center. Additionally, the district added new classrooms and improved its football stadium.
GCCISD's Stallworth Stadium is the home for varsity football and soccer for GCCISD as well as for the annual Bayou Bowl. It seats approximately 16,000 fans, making it one of the largest high school sports venues in the nation.
