Summary
Escuela Key Elementary is a PK–5 school in Arlington, VA, serving 572 students as part of Arlington County Public Schools. The school earned 4 stars in the 2025–26 state ranking, placing it 180th out of 1,111 Virginia elementary schools (84th percentile). Over the past four years, it has climbed 457 places in the state rankings, from 637th in 2021–22 to 180th in 2025–26, making it one of the fastest-improving schools in the area.
The school's academic strengths are most visible in math and Virginia Studies. In 2025–26, 94.3% of 3rd graders were proficient in math, compared to 80.9% districtwide, and 93.4% of 4th graders passed Virginia Studies versus 79.6% for the district. Reading scores were also above district averages in every tested grade. Attendance is another standout: only 6.3% of students were chronically absent in 2024–25, well below the district rate of 12.1% and less than half the rate at nearby Barrett Elementary (14.8%) and Carlin Springs Elementary (13.7%). The school also achieves strong results efficiently, spending $14,030 per student — below the average of nearby elementary schools and several thousand dollars less than lower-performing neighbors like Barrett ($20,535) and Campbell Elementary ($19,711).
Despite the strong overall results, the school's effectiveness varies by student group. State subgroup rankings show exceptional outcomes for White, multiracial, and male students, but lower ratings for low-income students (37th percentile) and disabled students (28th percentile). The male–female gap is notable, with male students ranking 37 percentile points higher than female students. Science remains the relative weak point, with 77.1% proficiency in 5th grade — above the district but the school's narrowest margin. Among nearby schools, Escuela Key sits between Arlington's elite cluster — Glebe Elementary (18th), Cardinal Elementary (20th), Arlington Traditional (82nd), Ashlawn Elementary (121st), and Arlington Science Focus School (176th) — and struggling schools like Barcroft Elementary (856th) and Carlin Springs Elementary (1,006th). If current trends continue, Escuela Key may soon rank alongside Arlington's very top elementary schools.
