Summary:
There are four elementary schools serving grades PK-5 in the 21075 zip code of Elkridge, Maryland, all part of the highly-rated Howard County Public Schools district, which ranks in the top 16% of Maryland districts.
Rockburn Elementary is the standout school in the area, earning a 5-star rating and ranking in the top 6% of Maryland elementary schools. It dramatically outperforms its peers in every academic subject, with 66.6% of students proficient in math and 75.3% in ELA, compared to the other schools which generally fall below district averages. Rockburn also has a remarkably low chronic absenteeism rate of 8.3% and a free/reduced lunch rate of just 12.33%. In contrast, Deep Run Elementary and Ducketts Lane Elementary are the lowest-performing schools, with rankings around the 50th percentile and free/reduced lunch rates exceeding 54%. Elkridge Elementary sits in the middle, with a consistent 3-star rating and proficiency rates that hover near state averages.
A key takeaway is that higher per-student spending does not guarantee better results—Deep Run and Ducketts Lane spend over $22,000 per student (the most in the area) yet have the lowest test scores, while Rockburn spends a more modest $18,033. Additionally, math proficiency is a universal weakness across all four schools compared to ELA, with the gap most pronounced at the lower-performing schools. Smaller class sizes at Deep Run and Ducketts Lane (ratios around 10.5:1) also do not translate to higher achievement, reinforcing that factors like socioeconomic status and attendance are stronger predictors of success. Ducketts Lane does show a positive trend, improving its state ranking from the 43rd to the 50th percentile over the past three years.
