Summary:
Zip code 21047 (Fallston, MD) is home to a single high school, Fallston High, which serves grades 9 through 12 and is part of the Harford County Public Schools district.
Fallston High presents a striking academic paradox. The school is a standout performer in English Language Arts (ELA), with 75.9% of students proficient in the 2025-2026 school year—far exceeding both the district (61.1%) and state (51.7%) averages. However, mathematics proficiency is a critical weakness, with only 10.4% of all students proficient, well below the district (28.4%) and state (27.1%). This is driven by extremely low scores in Algebra I (3.6% proficient) and Geometry (9.1% proficient). Interestingly, Algebra II scores (34.1%) are above the state average, suggesting that the students taking that advanced course may be a more select group. The school maintains a high graduation rate of 94.4% and a relatively low chronic absenteeism rate of 16.4%, with only 15.44% of students eligible for free or reduced lunch, indicating a relatively affluent student body.
The school's state ranking has shown a slight decline, dropping from the 77th percentile (4 stars) in 2024-2025 to the 70th percentile (4 stars) in 2025-2026. The stark contrast between ELA and math performance is the most notable takeaway, suggesting that while literacy instruction is a clear strength, math instruction—particularly in foundational courses—is a significant area for improvement. The high graduation rate despite low math scores raises questions about curriculum rigor and alternative pathways to graduation. Overall, Fallston High offers a strong ELA program and a supportive environment, but families should be aware of the pronounced challenges in mathematics.
