Summary:
There are five elementary schools serving grades PK through 5 in the 21136 zip code (Reisterstown, MD), all part of the Baltimore County Public Schools district, which ranks in the 28th percentile statewide and faces significant challenges.
Two schools stand out as top performers. Franklin Elementary is the academic leader, ranking in the 85th percentile with 53.2% math proficiency and 69.6% ELA proficiency—roughly double the district averages. Chatsworth School is a close second, ranking in the 73rd percentile, but excels in efficiency with the lowest chronic absenteeism rate (7.1% vs. 25.6% district average) and the lowest student-to-teacher ratio (10.4:1). Chatsworth also spends $32,808 per student, which is 76% more than the average of the other four schools. In contrast, Reisterstown Elementary, Cedarmere Elementary, and Glyndon Elementary struggle significantly, with math proficiency ranging from 15.3% to 29.2% and chronic absenteeism between 27% and 37.8%. These three schools also have higher free/reduced lunch rates (59-67%) compared to Franklin and Chatsworth (around 39%).
A key takeaway is the strong link between attendance and performance: Glyndon has the highest absenteeism (37.8%) and lowest scores, while Chatsworth has the lowest absenteeism (7.1%) and high scores. Math is a universal challenge, even at top schools, with proficiency trailing ELA by 10-16 percentage points. Franklin is on an upward trend, moving from the 69th to 85th percentile in two years, while Glyndon has declined from the 35th to 29th percentile. Resource allocation is uneven, with Chatsworth’s high spending and low ratios suggesting a specialized program driving its success.
