Construction on the current Grayson High School building began in August 1998 and the school opened its doors in 2000. The building has 65 classrooms, but as the student body has outgrown it, expansion is required. 42 trailers were formerly located in front of the building, until an expansion of the school was completed in time for the 2021 school year. The Grayson Technical Education School extends past the main high school building and has a greenhouse and Black Box theater among many other facilities. Most recently, the Grayson Technical Education School partnered with
Gwinnett Technical College to build a veterinary surgical suite. ==Feeder schools==
