Summary:

In zip code 21918, there is one elementary school, Conowingo Elementary, serving grades PK through 5 in the Conowingo, Maryland area as part of the Cecil County Public Schools district.

Conowingo Elementary is a school of contrasts, excelling in English Language Arts and Science while facing significant challenges in Mathematics. With 379 students, the school has a student-teacher ratio of 17:1 and spends $16,286 per student. The school's chronic absenteeism rate of 14.1% is notably lower than the district average of 21.9%, indicating strong student engagement. In the 2025-2026 school year, overall ELA proficiency reached 51.1%, matching the state average and exceeding the district's 46.9%. Fifth-grade science proficiency was a standout at 37.5%, far above both the district (20.9%) and state (32.4%). However, overall math proficiency was just 24.1%, below the state average of 27.1% and less than half the ELA score. A sharp drop in 4th-grade math proficiency to 16.7% (compared to 32.7% in 3rd grade) suggests a specific curriculum or instructional issue that needs attention.

The school has shown an upward trajectory in its state ranking, moving from the 48th percentile (2 stars) in 2023-2024 to the 51st percentile (3 stars) in 2025-2026. While math scores dipped in the most recent year, the school's consistent strength in ELA and Science, combined with low absenteeism and high per-student spending, paints a picture of a school with solid foundational practices. The primary takeaway for parents is that Conowingo Elementary provides a strong environment for reading and science, but has a clear and urgent need to improve its mathematics instruction, particularly in the 4th grade.
