Brock Independent School District is a public school district based in the community of Brock, Texas (USA).
Brock's basketball programs (girl's and boy's) have been perennial state powers, including an unusual "double-double" in 2001-2002 and 2002-2003, when both the girl's and boy's teams won consecutive titles. The feat was even more unusual in that, in February 2002, Brock was realigned upward in classification from Class A to Class AA (for the 2002-2003 season), moving it from being one of the largest Class A schools to one of the smallest Class AA schools, yet playing against larger Class AA schools Brock still managed to have both teams repeat as state champions. Brock moved up to Class AAA before the 2014-2015 season. Brock has won 11 state titles overall in basketball: girls in 2002, 2003, 2005, 2009, 2010, 2011, 2012, and 2013 and boys in 2002, 2003, and 2015. Brock has since won a state championship in every sport offered; baseball, softball, volleyball, cross country, track, golf, and tennis. Until 2011 Brock was one of the few districts in Texas that did not participate in high school football. In 2011, Brock began playing football at the junior high level, and in 2012 began playing high school football at the junior varsity level; in 2014 the program became varsity level; and a year after, Brock football won state.
In 2009, the school district was rated "recognized" by the Texas Education Agency.
