About Glendale Union High School District
Glendale Union begins at ninth grade, receiving students from several independently governed K–8 districts across central and northwest Phoenix. Address assigns the ordinary comprehensive campus among nine high schools, so the transition brings a new governing board, boundary system, transportation plan, and secondary course catalog at the same time.
GUHSD Online adds two operating formats separate from the nine comprehensive high schools. One option is completed from home; the Online Learning Academy provides an in-person setting for students using online coursework. Both change the student’s daily structure while remaining inside the high-school-only district. Career and technical education, advanced courses, athletics, and campus activities are distributed across the comprehensive schools. The first secondary decision is the assigned school or online format; the student is no longer continuing within the elementary district.
