Summary
Cardinal Elementary is a pre-K–5 elementary school in Arlington, VA, serving 682 students as part of Arlington County Public Schools, a district ranked in the top 20% of Virginia school divisions. Cardinal is one of the highest-performing elementary schools in the state, ranking 20th out of 1,111 Virginia elementary schools in 2025–2026 — the 98th percentile with a 5-star rating — and this is no one-year fluke: the school has ranked in Virginia's top 25 every year since 2022–2023 (including #15 in 2023–2024) and has held a 5-star rating for five consecutive years. Even during the pandemic-disrupted 2020–2021 school year, Cardinal remained in the 90th percentile.
Test scores at Cardinal are exceptional across every subject and grade level. In 2025–2026, 5th-grade math proficiency reached 97.4% (vs. 72.4% statewide), 5th-grade reading hit 94.8% (vs. 72.4%), and 5th-grade science reached 93.2% (vs. 68.8%). The school also posts remarkably low chronic absenteeism — just 4.2% in 2024–2025, less than one-third the statewide rate of 14.8%. Among nearby Arlington elementary schools, only Nottingham Elementary (#8), Tuckahoe Elementary (#17), and Glebe Elementary (#18) rank at or above Cardinal, while Cardinal outranks Arlington Traditional (#82), Ashlawn Elementary (#121), and Discovery Elementary (#35). Cardinal achieves these results with a larger student body than any of those peers.
What makes Cardinal especially notable is its efficiency: it spends less per student ($11,213 in 2023–2024) than every comparable nearby school, including Barrett Elementary ($20,535), Carlin Springs Elementary ($19,050), and Ashlawn ($15,327). Cardinal serves a relatively low-poverty population, with 6.7% of students qualifying for free/reduced lunch, and its attendance is among the best in the region. The school also performs strongly for many subgroups: White, multiracial, and disabled students rank in the 89th–99th percentiles statewide. Hispanic and low-income students, while likely scoring above state averages, do not reach the same elite percentiles — an equity gap worth noting for an otherwise outstanding school.
