Nearby comparisons are stark: Hale Elementary School, about 0.65 miles away, ranks in the 76th percentile and beats state averages in all three subjects, while Hernandez Elementary School (58th percentile) and Mendell Elementary School (49th) also far outperform Ellis. Ellis does beat King Elementary School in all three subjects and matches Trotter Elementary School in math, but trails Winthrop Elementary School, Kennedy John F Elementary School, Bridge Boston Charter School, Mendell, Hernandez, and Hale in nearly every subject. Its highest grade-level ELA score is 18.37% (4th grade) and highest math score is 13.64% (6th grade); every grade-level ELA and math cell is below 20%.
Ellis's relative strengths are in some subgroup rankings: English Language Learner students rank 47th percentile in 2025–2026 (57th in 2024–2025), and special education students climbed to 37th percentile from 9th the prior year, though low-income students remain at 8th percentile. Ellis spent $27,935 per student in 2020–2021 — more than nearby Hale, Hernandez, Mendell, Kennedy, and Trotter — yet posts much lower proficiency, and its student-teacher ratio rose from 8.8 in 2022–2023 to 12.4 in 2024–2025. The data point most toward targeted work in science and math and the low-income subgroup.
