In November 2017, voters in the Queen Creek Unified School District approved a $63 million bond package, as well as the repurposing of a 2014 bond, to allow the district to build a new high school and two new elementary schools, after a $95 million proposal had been defeated in 2016.[4] The new schools, in the northern part of the district, would alleviate lengthy commutes.[1] In August 2018, the district voted to name the school Eastmark High School, after the community in which it is located.[5] Ground was broken on the high school on March 29, 2018,[6] and the first day of classes for 800 students in grades 7 through 10 was July 31, 2019.[1]
The school, currently with 154,000 square feet (14,300 m2) of space, is planned to allow the construction of two further phases to bring its capacity from 1,350 to 2,800; the future phases would add a performing arts center, auxiliary gym, additional classrooms and an auditorium.[7]
