Summary:
The 21030 zip code in Cockeysville, Maryland, is home to two public elementary schools, Padonia International Elementary and Warren Elementary, both part of the Baltimore County Public Schools district, serving grades PK-5.
Warren Elementary is the standout school in this area, consistently outperforming Padonia International Elementary across nearly all academic metrics. Warren holds a higher state ranking (388th out of 864 schools, 3 stars) compared to Padonia (589th, 2 stars) and shows an improving trend. In the 2025-2026 school year, Warren’s English Language Arts proficiency rate was 50%, significantly higher than Padonia’s 28.9%, and it also led in math (31.5% vs. 28.3%) and science (34.3% vs. 12.5%). Notably, Warren achieves these results despite having a higher student-teacher ratio (15.8:1) and lower per-student spending ($17,674) than Padonia ($20,927), which spends over $3,000 more per student yet sees lower academic outcomes. Both schools share a chronic absenteeism rate of 25.3%, matching the district average, and both experience a notable drop in 5th-grade math proficiency, suggesting a common challenge in preparing students for advanced concepts.
For parents, Warren Elementary is the stronger choice, outperforming district averages in math, ELA, and science, while Padonia International Elementary struggles to meet state averages despite its specialized "International" focus and higher spending. The higher free/reduced lunch rate at Padonia (64.75% vs. 51.44%) may indicate it serves a more disadvantaged population, but the data clearly shows Warren delivers better academic results with fewer resources. Overall, families in 21030 have a clear disparity between the two schools, with Warren emerging as the top performer in the zip code.
