Summary:
Zip code 20016 in Washington, DC is home to three public elementary schools — Janney Elementary School, Mann Elementary School, and Key Elementary School — all serving Pre-K through 5th grade as part of District of Columbia Public Schools, with a combined enrollment of 1,451 students. This is an exceptionally strong cluster of schools: all three earned 5 stars and rank in the top 11 out of 124 DC elementary schools, despite the district overall being rated just 3 stars.
Janney is the clear academic leader, ranking #2 in DC with the highest math proficiency (87.4%) and strongest science results (68.75%), while also spending the least per student at $21,694. Key is the most improved school, jumping from #11 to #4 in a single year with the largest gains in both ELA (73.8% to 82.0%) and math (74.6% to 82.8%); it also leads the group in ELA and posted the zip code's single highest grade-level score — 94.7% math proficiency in 4th grade. Mann ranks #11 overall and offers the most favorable student-teacher ratio (12.4) and best 3rd-grade math (92.8%), but it spends the most per student ($26,975) while trailing its peers on most other measures.
All three schools dramatically outpace the DC district averages of 44.1% in ELA and 33.3% in math, combining to roughly 80% ELA and 83% math proficiency across the zip code. A notable pattern: 5th-grade math is a consistent weak spot at every school, with Key's drop from 94.7% in 4th grade to 67.7% in 5th grade being the most striking. Spending and class size do not clearly explain performance — Janney achieves the best results with the highest student-teacher ratio and lowest spending, suggesting curriculum, school culture, and parent involvement play significant roles. Missing free/reduced lunch data limits socioeconomic context, but the academic picture is clear: this zip code offers three outstanding elementary options.
