Original Research by School Decision on Glassmanor Elementary
Glassmanor Elementary serves kindergarten through fifth grade in Oxon Hill, a suburban unincorporated community in Prince George’s County. The school is a regular public school within the Prince George’s County Public Schools district, and it operates as a neighborhood elementary school. It is not a charter school, and its magnet status was not provided in the available data.
The student body is principally Hispanic, with a smaller share of Black students and very few students identifying as White or two or more races. A substantial share of students qualifies for free or reduced-price meals, placing the school in a high-poverty context. Data on the share of students with Individualized Education Programs (IEPs) and the share of English learners was not reported, so a parent may wish to ask the school directly about the availability of special education services and language support programs.
State testing results from the Maryland Comprehensive Assessment Program (MCAP) and the Maryland Integrated Science Assessment (MISA) are available for the most recent school year. In reading, the share of students scoring proficient or above was in the low teens to low twenties across grades three through five, with fifth graders posting the highest result. In math, proficiency rates were lower, dropping sharply by grade five. In fifth-grade science, no student scored proficient. These are soft spots, and a parent may want to look into this further with the school to understand what interventions and supports are in place. Only one year of assessment data was provided, so there is no trend information to indicate whether performance is improving or declining.
Because Glassmanor Elementary serves only elementary grades, there is no graduation rate to report, nor are there data on chronic absenteeism or discipline. The school’s locale and walkability profile were not available in the data provided, though Oxon Hill is car-dependent overall, with the heavily traveled Capital Beltway bisecting the area and major arterials such as Indian Head Highway and Oxon Hill Road serving as main routes. The community has no traditional downtown; schools are distributed across the CDP. The area’s most significant growth driver is the National Harbor mixed-use development on the Potomac River, which includes a casino resort, hotels, retail, and office space, along with the Gaylord National Resort & Convention Center. The housing market in the school’s zip code shows typical home values and rents that are below nearby state benchmarks, and both home values and rents have seen a slight decline recently. The broader regional unemployment rate is modest, and median household income sits in the low-to-mid five figures nationally.
The parent district, Prince George’s County Public Schools, has implemented a district-wide literacy initiative using evidence-based reading curriculum aligned with the science of reading, which directly affects how elementary students at Glassmanor are taught to read. The district also approved an operating budget increase that directs additional funding toward teacher salaries and student support services. A boundary review was conducted in 2024, with proposed changes for the 2025-2026 school year that could affect attendance zones, so families should confirm current assignment boundaries.
Oxon Hill itself is an unincorporated CDP with no centralized civic core; its public amenities include the Oxon Hill Library (which houses a notable African American research collection), Oxon Cove Park and Farm operated by the National Park Service, the Tucker Road Athletic Complex with an ice skating rink, and the Southern Regional Technology & Recreation Complex. Major employers are concentrated in tourism and hospitality at National Harbor, along with the local school system and healthcare providers. The community has experienced steady population growth tied to the National Harbor development and its proximity to Washington, D.C., and the school-age population likely reflects that broader demographic trend.
For parents considering Glassmanor Elementary, the picture is of a high-poverty elementary school where state assessment results are low relative to state averages, in a community that is car-dependent and experiencing development-driven growth. The district is in the middle of a literacy curriculum overhaul and a budget increase for support services, which could affect what happens in the classroom over time. A family should tour the school, speak with staff about the specific reading and math interventions being used, and ask about English learner support and special education services if those are relevant to their child.
