Glenn Harmon Elementary serves kindergarten through fourth grade in Arlington as part of Mansfield ISD. The school is small, with an enrollment of just over four hundred students. The student body is racially diverse, with Black students making up the largest share, followed by Asian, Hispanic, and White students in smaller numbers. A substantial majority of students qualify for free or reduced-price lunch, reflecting the economic circumstances of the families the school serves.
On the most recent state assessments in math and reading, Glenn Harmon's results are below the midpoint among schools in Tarrant County. In third and fourth grade math, proficiency rates fall in the range where roughly one in four or fewer students score at the proficient level or above. In reading, third and fourth grade proficiency rates are similarly low. When looking at all performance levels together, the school shows a modest portion of students meeting or exceeding standards, while a larger share are approaching standards and a meaningful group are still developing foundational skills. These outcomes suggest the school faces academic challenges that a parent may want to look into further with the school directly, including what interventions are in place and how the school is targeting improvement.
The school offers two clubs: Audio Visual Club and Student Council. Beyond this, the profile does not specify additional program offerings or specialized services. State data on special education enrollment, English learner populations, and attendance are not available.
Mansfield ISD, the district housing Glenn Harmon, has undergone significant change recently. In May 2024, voters approved a substantial bond package for facility upgrades including HVAC, roofing, plumbing, and electrical systems, weapons-detection equipment, and a new Pre-K center. Property tax rates in the district have fallen for five consecutive years, though rising property appraisals have offset some of those cuts for homeowners. In 2021, voters also approved a Penny Swap measure that moved a portion of the tax rate from debt service to instruction without raising the total rate, generating ongoing revenue for classroom instruction and student programs. These fiscal moves position the district as willing to fund schools and seek tax restructuring without rate increases, though the actual impact on Glenn Harmon's classrooms and resources would require direct conversation with the school.
Housing in the Arlington zip code is moderately valued for the region. The median home value is somewhat below both state and national benchmarks, and monthly rental costs are correspondingly lower. The affordability picture is tight: mortgage costs represent a significant portion of household income, and rent likewise occupies a meaningful share. The unemployment rate is moderate, and median household income in the region is solid.
Glenn Harmon is a straightforward, non-selective public elementary school serving an economically modest and racially diverse neighborhood. Its test outcomes are below county norms, which means a family considering this school should understand the academic starting point and ask directly what the school is doing to raise achievement, how progress is tracked, and what supports exist for students not yet proficient.
