Best Elementary Schools in Zip Code 20015

Zip code 20015 is served by a single public elementary school, Lafayette Elementary School, which enrolls students in grades PK through 5 and stands out as one of the highest-performing elementary schools in Washington, D.C. Because this zip code has only one elementary school, there are no other local schools to compare it to directly, so the most meaningful comparisons are against the broader District of Columbia Public Schools (DCPS) district and the D.C. statewide averages.

Lafayette is a clear standout by nearly every available metric. It has earned a 5-star rating for three consecutive years, ranking 3rd, 4th, and 2nd among all D.C. elementary schools in the 2025–2026, 2024–2025, and 2023–2024 school years respectively — placing it in the top 2–4% of the district each year. In contrast, DCPS as a whole ranks 19th out of 46 D.C. districts with a 3-star rating. Academically, Lafayette’s proficiency rates are dramatically higher than both district and state averages. In English Language Arts, 80.2% of students scored proficient versus 44.1% for DCPS and 39.6% statewide. In math, the gap is even larger: 85.4% proficient versus 33.3% for the district and 28.2% statewide. The school’s math performance is particularly strong in upper elementary, climbing from 81.1% proficiency in 3rd grade to 88.9% in 5th grade.

While science proficiency at 60.54% is lower than the school’s own reading and math scores, it is still about 2.6 times the DCPS average and 3 times the statewide average. Lafayette also benefits from favorable resources, including a student-teacher ratio of 14.6:1 and per-student spending of $21,010. Year-over-year results are remarkably stable, with ELA holding at about 80% and math showing a slight gain from 84.3% to 85.4%. One caveat is that free/reduced-lunch data is not reported, so it is not possible to assess socioeconomic demographics. Overall, for families in zip code 20015, Lafayette Elementary School is an elite, consistently high-performing public school that greatly exceeds district and state benchmarks in every subject and grade level measured.
