2005-2006 school years, the district was dropped to the "Recognized" ranking. In the 2006–2007 school year, the district not only regained the "Exemplary" ranking, but also became the largest all-Exemplary school district in Texas. Carroll ISD still holds this title today. Carroll ISD also staffs all of its schools with campus resource officers. All officers are full-time members of the Southlake Police Department. The decision to expand the resource officer program (which had previously included only two officers and a sergeant) was made in the wake of the 2012 school shooting in Newtown, Connecticut. The program now includes 11 officers and one sergeant. Demographics In 2021 the median price of a single family residence in the district was $650,000. Mascot All of the district's schools share the same colors (green, white, and black) and the same mascot (the Dragon). The mascot was created by a student in the mid-eighties by combining an outline of Texas with a US Navy electronic warfare squadron emblem. The logo was first used in the 1980s as helmet emblems for the Carroll Dragon Varsity Football teams and gradually adopted as the district mascot. Previously, Carroll Middle School used the mascot of the Knights, using the same color scheme as the Dragons. The Knights mascot was retired in the 1990s.
