Best Public Schools in Zip Code 21046

The three public schools in zip code 21046 (Columbia, MD) are all part of the highly-rated Howard County Public Schools district and serve students from elementary through high school, presenting a diverse educational landscape within a single, well-regarded area.

Atholton Elementary is the standout performer, earning a 4-star rating and ranking in the 85th percentile statewide. It significantly outperforms district averages in math (55% proficient vs. 42.1%) and English Language Arts (68% vs. 65.9%), while also having the lowest rate of economic disadvantage (15.89%) and chronic absenteeism (11.8%). In stark contrast, Guilford Elementary faces the most challenges, with a 2-star rating, the highest rate of economic disadvantage (46.45%), and academic proficiency rates well below district averages. Interestingly, Guilford receives the highest per-student funding ($21,939) and has the best student-teacher ratio (11.9:1), showing that spending alone does not guarantee performance. Hammond High presents a mixed profile: it excels in English Language Arts (77.1% proficient, well above the district) but struggles with math (12.8% proficient) and has higher-than-average dropout (6.4%) and chronic absenteeism (22.9%) rates. However, Hammond High is on a positive upward trend, improving its state ranking from the 38th percentile to the 64th percentile over the past two years.

The key takeaway for parents is the dramatic contrast between the two elementary schools, highlighting how factors like socioeconomic background and school climate can drive outcomes more than funding. While Atholton Elementary offers a high-performing, stable environment, Guilford Elementary requires more support despite greater resources. Hammond High offers strong ELA instruction but has notable climate issues that families should investigate, though its recent improvement is encouraging. Overall, this zip code provides a range of school experiences within a top-tier district, making it essential for parents to consider each school's unique strengths and challenges.
