Summary:
The two elementary schools in El Paso-Gridley CUSD 11 enroll 426 students across prekindergarten through grade 4: Jefferson Park School serves PK–2, and Centennial School serves grades 3–4. The supplied IAR results cover only Centennial, so they cannot establish an academic ranking across both schools. The clearest academic finding is that Centennial’s 2025–2026 math proficiency was 15 percentage points above the state.
Centennial stands out in the available results: 54% of students were proficient in all-grades math, compared with 40% statewide, while ELA proficiency was 61%, versus 56% statewide. Its math result was also 7 points above the district’s, though its ELA result was 6 points below the district’s. The grade-level pattern is especially strong in third-grade ELA, where proficiency was 65% compared with 48% statewide, a 17-point advantage; fourth-grade ELA was 57% versus 56%, a 2-point advantage. Jefferson Park has no supplied test results, so there is no supported basis to call either school the lowest-performing.
Centennial improved from 2024–2025 to 2025–2026: math proficiency rose 10 points, compared with a 1-point statewide increase, and ELA rose 4 points, compared with 3 points statewide. Its SchoolDigger percentile rank also increased from 57 to 61 over those years; Jefferson Park’s older SchoolDigger history declined from 76 to 61 between 2005–2006 and 2007–2008, so the periods are not directly comparable. Other school differences offer context, not an explanation for achievement: in 2024–2025, student–teacher ratios were 12.4 at Jefferson Park and 13.6 at Centennial, and the free/reduced lunch eligible shares were 40% and 34%, respectively. In 2025–2026, chronic absenteeism was lower at Jefferson Park, at 4%, than at Centennial, at 9%; both were well below the state’s 24%.
