Allen High School is a public, co-educational secondary school in Allen, Texas (United States). It is the only high school in the Allen Independent School District.

History The first Allen High School, built in 1910 at the corner of Belmont and Cedar, was a two-story brick building housing six classrooms and an auditorium, and saw the first graduating class of eight students in 1914. The second Allen High School was established in 1959 on land donated by Mr. Harris Brown on the corner of Jupiter and Main Streets. August 1999 saw the opening of Allen High School "2000," a new facility (at the corner of Greenville and Rivercrest) which opened to 2,200 students in grades 10 through 12. The former high school was converted into the Becky Lowery Freshman Center, named in honor of a former middle school teacher and school counselor. In 2018, the building was partly demolished and replaced with a new building on an adjacent plot of land on Greenville Ave. The southernmost part of the school was renovated into the Dillard Special Achievement Center, while the northern section became a parking lot. The football stadium still stands. The new building started serving grade 9 students during the 2018–19 school year, and had an enrollment of 1,634 in 2015–16. The final expansion of the school was completed in 2011. The expansion included a new 1,500 seat performing arts center, an expansion of band hall space and a Career and Technology Education center featuring a student-managed restaurant open to the public, a student-managed apparel store with student-designed items, multiple new Mac labs, Mac-equipped rooms for the photojournalism, yearbook, commercial photography, audiovisual, radio, and newspaper classes as well as learning-classrooms for the medical education programs.
