Summary

Tres Rios Elementary School serves 713 students from prekindergarten through grade 8 in Tolleson, within the Littleton Elementary District, near schools such as Hurley Ranch Elementary and Country Place Elementary. In 2025–26, students were proficient at rates of 24% in English language arts (ELA) and 15% in math, below district rates of 27% and 17% and state rates of 41% and 33%. The most important takeaway is that results trail the district and state in both subjects, even though they are slightly above nearby-school averages.

Compared with nearby schools, Tres Rios is modestly ahead overall but has some clear grade-level strengths and gaps. Its all-grade ELA rate is about 1 point above the nearby average of 23%, and math is 3 points above the nearby average of 12%. Fourth-grade math is a relative bright spot: Tres Rios scored 28%, above the district’s 21% and tied with Country Place among nearby schools with results, though below the state’s 40%. By contrast, sixth-grade ELA was 19%, 9 points below the district, while eighth-grade math was 12%, below the district’s 16% and state’s 30%. Among nearby schools with eighth-grade math results, Tres Rios was ahead of Country Place but behind Hurley Ranch and Arts Academy at Estrella Mountain.

Available science results improved: fifth-grade proficiency rose from 16% in 2022–23 to 19% in 2024–25, and eighth-grade proficiency increased from 9% to 15% between 2022–23 and 2023–24. SchoolDigger’s statewide percentile fell from 29 in 2023–24 to 12 in 2025–26; its current rating is 1 star, but its percentile is around the middle of nearby schools with current data. The student–teacher ratio was 16.5 in 2023–24, down from 19.6 the year before, and the reported free/reduced-lunch rate was 72% in 2022–23—context, not a basis for comparison with nearby schools. One notable subgroup shift: SchoolDigger’s statewide ranking for how well Tres Rios serves male students dropped from the 28th percentile in 2023–24 to the 2nd in 2025–26, while the school’s overall percentile moved from 29 to 12.
