Summary:
Zip code 21104, located in Marriottsville, MD, is home to a single high school, Marriotts Ridge High, which serves grades 9-12 and is part of the highly-rated Howard County Public Schools district.
Marriotts Ridge High is a standout performer, consistently ranking in the top 10% of all Maryland high schools and earning a 5-star rating. With an enrollment of 1,741 students, the school demonstrates exceptional strength in English Language Arts (ELA), where 89.5% of students are proficient—far exceeding both the district (65.9%) and state (51.7%) averages. The school also benefits from low chronic absenteeism (15.4%) and a relatively low percentage of students receiving free or reduced lunch (15.51%), factors that contribute to a stable learning environment. Per-pupil spending is $16,985, reflecting a significant investment in student resources.
The most notable finding is a stark "math paradox." While ELA scores are elite, overall math proficiency (36.4%) lags behind the district average (42.1%). This is driven by a critical bottleneck in Algebra I, where only 18.1% of students are proficient—a rate below the state average. However, students who advance to Algebra II perform strongly (43.5% proficient), suggesting that while foundational math instruction may need attention, the school excels at developing higher-level math skills. The school's state ranking has seen a slight, gradual decline from 11th (2023-2024) to 18th (2025-2026), a trend worth monitoring but not alarming given its continued top-tier status.
