The Colony High School, located in The Colony, which opened in 1986 is part of Lewisville ISD. Seniors of the 1987 class attended Lewisville High School as TCHS initially had only grades 9–11.
Academics
The Colony High School offers a standard Texas high school curriculum as defined by the Texas State graduation requirements. In addition to those minimum requirements, The Colony High School also offers numerous College BoardAdvanced Placement (AP) courses that gives students the opportunity to qualify for college credit. Also a new addition to The Colony High School's academic help for the students is a program nationally known as AVID; Advancement Via Individual Determination which is a class for students who want to get into college. The class teaches them ways to take college level notes, self-discipline necessary for getting work done in college while giving them the opportunity to meet professionals in the field and allowing the students to go on field trips to college campuses. TCHS was the first high school in LISD to have the AVID program under the initial instruction of Jennifer Adams, Coach Dietzman, and this year's AVID teacher for the juniors and seniors; Reesa Wilkins. Recently, all LISD schools, including The Colony High School, entered into a partnership with local community colleges to offer students dual-credit summer courses that, if passed, qualifies as credit for both high school graduation and college. In 2008/09 a new band hall, drum room, color guard room, and practice rooms were added.
Facilities
By 2013 the school established a coffee and light meal shop.[3]
