Summary
Thomson Elementary School is a PK–5 public school in Washington, DC, serving 259 students at 1200 L St. NW as part of District of Columbia Public Schools. For 2025–2026, Thomson ranks 53rd of 124 DC elementary schools, in the 57th percentile with 3 stars. Within a mile of campus, Ross Elementary School and School-Within-School at Goding rank among the top ten elementary schools in DC with 75–87% proficiency in reading and math, while Walker-Jones Education Campus, Cleveland Elementary School, Center City PCS - Shaw, and KIPP DC - Lead Academy PCS trail far behind, sometimes below 20% proficiency. Thomson, Seaton Elementary School, and Garrison Elementary School form the middle tier between these two extremes.
Math is a relative strength: overall math proficiency is 31.4%, above the state average, and 3rd-grade math reaches 44.4%, nearly matching district levels. Fifth-grade science also edges past the state average. English Language Arts is the larger concern — overall ELA proficiency is 37.7%, below the district average of 44.1%, and 4th-grade ELA drops to 27.3%, almost 19 points behind the district. Thomson shows genuine strengths with specific student groups: low-income students ranked 12th of 92 schools statewide in 2024–2025, and the school previously earned top-five rankings for English Language Learners. Hispanic students, however, have earned just 1–2 star ratings in recent years, an area worth monitoring.
Thomson spends generously — $30,791 per pupil in 2023–2024, more than higher-performing neighbors like Ross Elementary School ($25,648) and School-Within-School at Goding ($27,522) — and maintains a very low student-teacher ratio of 8.2:1. Yet those resources haven't produced top-tier results, suggesting money and staffing alone don't determine outcomes. Rankings have been volatile, bouncing between the 40th and 71st percentiles over recent years, a pattern amplified by small enrollment. The upward trend from a 2-star low in 2023–2024 to 3 stars is encouraging, but sustained progress in reading will be essential.
