Summary
Jefferson Elementary serves 507 students in kindergarten through sixth grade in Dinuba, in the Dinuba Unified area. Its results vary sharply by grade: fifth and sixth grade are strong, while third grade and especially fourth-grade English language arts (ELA) are weak. In ELA, 54% of fifth graders and 57% of sixth graders are proficient, compared with 30% of fourth graders; in math, the school’s strongest subject overall, proficiency ranges from 34% in third grade to 43% in fifth. The most important finding for families is that all-grade averages conceal a pronounced split between strong upper-grade results and much weaker results in lower grades.
Compared with five nearby schools serving the same grades, Jefferson ranks second of six in math, fifth in ELA and third in science. Its 39% all-grade math proficiency is just above the state’s 38% and 7 points above the district’s 32%; it is also slightly above the nearby-school average of 38%, though below Grand View Elementary at 40%. ELA is a relative weakness: Jefferson’s 45% is below the state by 4 points, the district by 6 points and the nearby-school average by 3 points. Science is its largest state-level gap: 26% proficiency is 10 points below the state, although it is 1 point above the district and 3 points above the nearby-school average. Jefferson leads nearby peers in fifth- and sixth-grade math and ELA, but has the lowest fourth-grade ELA result among the six.
Results have declined since 2022–2023: ELA fell 7 points, math 3 points and science 8 points, while the state improved in all three subjects. There has been a modest recent rebound in math and science, but Jefferson’s SchoolDigger ranking is 2,708 of 5,804 California schools, at the 53rd percentile with 3 stars, down from the 66th percentile in 2023–2024. Its student–teacher ratio was 21.5 in 2024–2025, below the nearby-school average of 23.1; 81% of students were free/reduced lunch eligible that year. SchoolDigger’s statewide subgroup ranking for English Language Learner Students reached the 94th percentile in 2023–2024, compared with the school’s overall 66th percentile that year. For Hispanic Students, its ranking was at the 68th percentile in 2025–2026, above the overall 53rd percentile, but down from the 85th percentile in 2023–2024.
