Summary
Langley Elementary School is a PK-5 public school in the District of Columbia Public Schools system, serving 348 students in the 101 T Street NE area of Washington, DC. The school currently holds a 1-star rating and ranks in the bottom quartile of all DC elementary schools, placing 104th out of 124 in the 2025-2026 school year. Academic achievement, as measured by the 2025-2026 DC CAPE assessments, is low, with only 13.5% of students proficient in English Language Arts and 12.3% proficient in math—figures that are roughly 30 points and 21 points below the respective DCPS district averages of 44.1% and 33.3%.
While the school's overall performance is a concern, its results are uneven across subjects and student groups. Langley's ELA proficiency is particularly weak compared to nearby same-district schools like Cleveland Elementary School, which posted 25.5% proficiency, and Walker-Jones Education Campus at 23.9%. The contrast is even starker with high-performing nearby charter schools such as Inspired Teaching Demonstration PCS (63.3% ELA) and Mundo Verde Bilingual PCS - J.F. Cook (43.2% ELA). However, within the school, African American students perform at the 44th statewide percentile, significantly better than the school's overall 16th percentile. In contrast, low socioeconomic status students rank at just the 12th percentile, indicating that the school serves economically disadvantaged students far less effectively.
Langley's spending and staffing levels are broadly in line with or better than higher-performing nearby schools, with per-pupil spending around $27,000 and a student-teacher ratio of 11:1. Despite these resources, the school has not achieved strong academic outcomes, and its ranking has been volatile over the past decade, never reaching the top half of DC elementary schools. The school is also located in a neighborhood with a highly competitive school-choice environment, which, combined with its persistently low test scores, may affect its ability to attract families. The ELA proficiency gap with the district also widens by grade level, with 3rd grade at 12.9% versus a district average of 38.0%, and 5th grade at 10.1% versus 44.0%, suggesting students may fall further behind as they progress.
