Horizon School, Glendale AZ - Test Scores & Data

Original Research by School Decision on Horizon School

Horizon School is a regular public elementary and middle school in Glendale, Arizona, serving students from kindergarten through eighth grade as part of the Glendale Elementary School District. The school sits within a large suburban city that borders Phoenix, a place defined by a mix of historic neighborhoods, major retail corridors, entertainment venues, and industrial employers like Honeywell Aerospace, as well as Luke Air Force Base. Glendale’s landscape is mostly auto-oriented, with concentrated walkable zones in Historic Downtown and the Westgate Entertainment District. The city has been growing steadily, and its Sports and Entertainment District development plan is intended to spur further growth, particularly in the western part of the city near State Farm Stadium and Desert Diamond Arena.

Horizon School enrolls a substantial student body for a K-8 campus. The student population is diverse, with a majority of students identifying as Hispanic, a substantial white population, and smaller shares of Black, Asian, and students of two or more races or American Indian or Alaska Native heritage. Data on the share of students qualifying for free or reduced-price lunch, as well as on students with disabilities and English learners, was not available. A parent may want to ask the school or district directly about these supports, as they are relevant to understanding the full student context.

The school’s academic performance on state assessments, based on results from the 2024-25 school year, shows a pattern of proficiency rates that are below the midpoint among districts in Maricopa County. In English language arts, the share of students meeting proficiency varied across grades, with the highest rate in seventh grade and the lowest in third grade. In math, proficiency rates were lower across nearly every grade, with the highest in third grade and the lowest in fifth grade. Science results were also low, with a modest share of fifth graders and a larger share of eighth graders scoring proficient. The overall proficiency index for the school, which averages performance across all tested subjects and grades, places Horizon below the midpoint compared to other schools in Maricopa County. A parent reviewing these results should weigh them against their own expectations for academic preparation.

Because Horizon serves only grades K-8, there is no graduation rate to report. The school does not offer the high school programs like Advanced Placement, career and technical education pathways, or dual-credit courses that families of older students might look for. The school’s website and directory details did not list any specific special programs or magnet status, and civil rights data such as discipline or chronic absenteeism rates were not available for this report.

In terms of the local housing market, the community around Horizon has seen home values decline recently, and rents have held relatively steady. The typical home in the area is priced below the statewide benchmark, and renting is notably cheaper than buying with a mortgage at current interest rates, which may be relevant for families considering a move.

Overall, Horizon School is a mid-sized K-8 school in a growing suburban city with a diverse student body and academic results that sit below the county midpoint. Families seeking a school with strong academic performance relative to other options in the county will want to examine the specific grade-level results for their child’s age group and inquire about supports that were not reported here. The absence of data on free or reduced-price lunch, special education, and English learner populations is a gap worth exploring directly with the school, as it affects the full picture of what a student might experience.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
