The top reported proficiency rate is 62% in English language arts. The lowest is 12% in Science.
Original Research by School Decision on District of Columbia International School
District of Columbia International School, known as DCI, is a public charter school in upper Northwest Washington serving grades six through twelve. It sits in the 20012 zip code, an area where home values run well above the statewide benchmark and rents are correspondingly elevated. The school itself occupies a single campus on Main Drive NW, positioned within a city that, as publicly reported sources describe, is built around the federal government and international institutions rather than a traditional commercial downtown. The neighborhood context is urban and transit-connected, with the broader D.C. landscape shaped by the L'Enfant Plan's diagonal avenues, the National Mall's civic axis, and a workforce that swells with Maryland and Virginia commuters each weekday.
The student body is large for a single secondary campus and reflects the cosmopolitan character of the city itself. Hispanic students form the largest group, followed by Black students, with a sizable White population and meaningful representation from students of two or more races and Asian students. This is a genuinely diverse enrollment by race and ethnicity, which aligns with the school's publicly reported international focus. Several demographic indicators the payload does not carry: free-or-reduced-price lunch counts were not reported, special-education rates were not reported, and English-learner counts were not reported. A parent evaluating fit may want to ask the school directly about how it serves students with disabilities and multilingual learners, since the data here does not surface those figures.
Academically, the most recent state assessment results show a clear split between subjects. English language arts proficiency sits at a level most families would regard as strong, with well over half of tested students meeting or exceeding expectations. Math proficiency is more middling, with roughly four in ten students reaching that bar. Science results, drawn from a single grade-level administration, are low by comparison, with only a small fraction of eighth-grade test-takers scoring proficient. The school's participation rate in science was near universal, so the low result is not an artifact of low turnout. A parent may want to look into how the school teaches science across the middle grades and what supports or curricular shifts are underway, since the result stands apart from the stronger ELA showing.
No multi-year trend data was available, so it is hard to say whether these results represent improvement, decline, or stability. The same gap applies to graduation rate: the payload does not include a graduation rate for this school, even though it serves through grade twelve. That is a data gap a family should ask about directly, since the high school years are a central part of what DCI offers.
The district brief notes that DCI operates an International Baccalaureate-for-all model and maintains language tracks, both of which are publicly reported features that shape the academic pathway here. An IB curriculum across all grades is an uncommon commitment and defines much of the school's identity, pulling pedagogy toward inquiry, extended writing, and interdisciplinary projects. The language program suggests sustained exposure to a second language rather than a brief exploratory cycle. No recent parent-relevant changes with lasting impact were identified in the search, which suggests a stable programmatic direction.
Housing in the surrounding zip code is expensive relative to both the state and national medians, with typical home values approaching the higher end of the D.C. market. Rents are elevated as well but grew only modestly year over year. For families considering renting near the campus, the cost is real but the urban setting and transit access may reduce dependence on a car.
What DCI offers is a structured IB pathway through middle and high school, a racially and ethnically diverse peer environment, and a location in a well-resourced part of the city. The academic picture is strong in literacy, adequate in math, and weak in science. Where the data is thin, on graduation, special populations, and economic indicators, the school itself is the best next source.
