Summary
Jefferson Elementary is a K–6 school in Calexico, California, serving 625 students in Calexico Unified. In 2025–26, its proficiency rates were below California’s in English language arts (ELA), math, and science. Its clearest academic concern is science: just 8% of students were proficient, compared with 36% statewide and 15% in the district, and Jefferson scored below every nearby Calexico Unified K–6 school.
Math is Jefferson’s strongest subject relative to its district and nearby peers, while science is its weakest. In 2025–26, 20% of students were proficient in math—2 points above the district—and Jefferson ranked third among the seven local K–6 schools. ELA proficiency was 27%, 3 points below the district, but also ranked third locally. Both subjects remained well below state results: 38% in math and 49% in ELA. Science proficiency was 8%, 7 points below the district and 28 points below the state; the other six local schools ranged from 9% to 23%. Attendance is another concern: chronic absenteeism was 47%, compared with 38% in the district and 18% statewide, making Jefferson the third-highest among its local school peers.
Jefferson’s science results have declined, while its ELA and math results have been broadly flat. From 2022–23 to 2025–26, science proficiency fell from 16% to 8%, and the gap with the state widened by 14 points. Chronic absenteeism rose from 30% to 47% over that period. SchoolDigger placed Jefferson at the 13th percentile and awarded it 1 star in 2025–26; its percentile was 22 in 2022–23. The 13th percentile was third-highest among the seven Calexico Unified K–6 schools, though four nearby schools outside the district ranked higher. In 2024–25, 92% of Jefferson students were free/reduced lunch eligible, the second-lowest share among those seven schools, and its student-teacher ratio of 26 was the highest reported among them. SchoolDigger’s statewide ranking for Special Education Students was at the 34th percentile in 2025–26, compared with the school’s overall 13th percentile; the subgroup result had been at the 12th percentile the year before. These rankings can shift substantially, and the data do not explain why they changed.
