Summary:

The Glendale Union High School District in Arizona consists of 11 high schools, including a mix of traditional public high schools and an online learning academy, serving students in grades 9-12. The district's schools exhibit a wide range of academic performance, with some standout schools like Thunderbird High School and Greenway High School consistently ranking among the top in the district and state, while others like Glendale High School and Cortez High School struggle to match their peers' academic performance.

The district-wide graduation rate of 78.4% is slightly below the state average, and the dropout rate of 5.2% is higher than the state average. Test scores also vary significantly, with the top-performing schools like Sunnyslope High School and Thunderbird High School boasting much higher proficiency rates in English Language Arts and Mathematics compared to the lower-performing schools. The district's per-student spending ranges from $9,115 to $16,546, with the online learning academy spending the most per student.

The data reveals a significant performance gap between the district's schools, suggesting that some may be struggling to provide the same level of educational opportunities and resources as the higher-performing institutions. This raises questions about equity and the effectiveness of the online learning program, which has the highest per-student spending but the lowest test scores and a 1-star rating from SchoolDigger. Overall, the Glendale Union High School District presents a mixed picture, with both high-achieving and underperforming schools, highlighting the need for a closer examination of the factors contributing to these disparities.
