Greenbrier Elementary School, Glendale AZ

Original Research by School Decision on Greenbrier Elementary School

Greenbrier Elementary School is a regular public school serving prekindergarten through sixth grade in the Deer Valley Unified School District. It sits in Glendale, a large suburban city that borders Phoenix and spans residential neighborhoods, major retail centers like Arrowhead Towne Center, entertainment venues in the Westgate area, and industrial employers including Honeywell Aerospace. The school itself is on West Greenbriar Drive, located in the northwestern part of the city.

The student body is diverse. White students make up the largest share, followed by a substantial Hispanic population, then students identifying as two or more races, Asian, American Indian or Alaska Native, and Black. The school enrolls a moderate number of students for an elementary, with reasonably balanced class sizes across kindergarten through sixth grade and a separate prekindergarten program. Data on the share of students qualifying for free or reduced-price lunch was not available, so a parent looking to understand the school's socio-economic profile would need to ask the district directly.

On state assessments in the 2024-25 school year, Greenbrier's results varied by grade and subject. In math, proficiency rates were highest among sixth graders and lowest among fifth graders, with a notable drop from third to fifth grade before rebounding in sixth. In English language arts, fourth graders posted the strongest proficiency rate, while third graders had the weakest. Fifth grade science results showed proficiency for somewhat less than half of students. Overall, the school's combined proficiency across tested subjects and grades places it just above the midpoint among elementary schools in Maricopa County. A multi-year trend shows that the school's proficiency rates have remained essentially flat, with no clear upward or downward movement across the limited years of data available. A parent may want to discuss with the school how it supports students through the grade-level transitions where performance dips, particularly in math between third and fifth grade.

The district overview did not reveal any recent bond elections, curriculum changes, or major budget decisions that would currently affect families. The school does not operate as a charter or magnet; it is a standard neighborhood elementary school within the Deer Valley system.

Housing in the Glendale area around the school is priced above the state average, with home values and rents both showing a modest year-over-year decline. The cost of owning a home relative to income is high, and monthly mortgage costs exceed typical rents, which is common in the current interest-rate environment. Glendale itself continues to grow steadily, with population increasing since the last census. The city's economy is anchored by Luke Air Force Base, Banner Health, the school districts themselves, and major retail and manufacturing employers.

Greenbrier Elementary offers a standard elementary academic program in a suburban Glendale setting. The proficiency picture is mixed, with some grades doing well and others falling short, and the school's overall performance sits in the middle of the pack relative to other county elementary schools. For a family weighing options, the key unknowns are the school's free-or-reduced-price lunch rate and its specific approaches to supporting students in the grades where test results drop. The housing market in this part of Glendale is expensive relative to the state, which shapes who can afford to live in the attendance zone. The school itself is a straightforward public elementary, not a specialized program, serving a diverse enrollment across a full prekindergarten through sixth grade span.

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.
