Glendale Union Online

Public, Virtual Grades 9-12

Summary

Glendale Union Online is a public virtual high school serving grades 9-12 in the Glendale Union High School District in Glendale, Arizona, with 379 students. While the district as a whole ranks 193 out of 297 Arizona high schools, Glendale Union Online consistently ranks in the bottom half, at 241 out of 270, and receives a 1-star rating from SchoolDigger.

Glendale Union Online's academic performance is a concern, with students consistently underperforming the district and state averages in proficiency rates for 11th-grade assessments in science, English language arts, and mathematics. For example, in 2023-2024, only 13% of Glendale Union Online students were proficient in science, compared to 20% for the district and 22% for the state. The school also has a lower 4-year graduation rate of around 78-85% and a higher dropout rate ranging from 3.4% to 27.6% in recent years, compared to the district's 3.9% to 6.1%.

While Glendale Union Online performs significantly worse than other high schools in the Glendale Union High School District, such as Cortez High School and Apollo High School, it appears to outperform some nearby charter schools, such as Crown Point High School and Kaizen Education Foundation dba Maya High School, which have even lower rankings and academic outcomes. The virtual nature of Glendale Union Online and the high percentage of free and reduced-price lunch recipients may be contributing factors to the school's lower performance, presenting opportunities for targeted interventions and support to address these challenges.
