Summary
Jefferson Elementary is a K–5 school in Carlsbad, California, with 471 students, in an area with elementary schools in both Carlsbad Unified and Oceanside Unified. Its 2025–26 proficiency rates were above California’s in ELA, math and science, but the clearest local finding is that Jefferson scored below all six nearby Carlsbad Unified schools in all three subjects.
Math is Jefferson’s strongest subject against state and district results, while science is its weakest against nearby-school averages. Students reached 51% proficiency in ELA, 49% in math and 39% in science—about 2, 10 and 3 points above state rates, respectively, but 20, 13 and 21 points below district rates. Nearby-school averages were 64% in ELA, 62% in math and 54% in science; Jefferson was about 12, 13 and 15 points lower, and ranked fifth-lowest among the 11 schools in each subject. Grade-level results point to particular concerns in third-grade ELA (39%) and fifth-grade math (35%), both below state rates and every nearby Carlsbad Unified school’s result for that grade.
Results are higher overall than in 2022–23: ELA rose 5 points, math 2 and science 4, though science has fluctuated sharply from year to year. SchoolDigger placed Jefferson at the 66th percentile and rated it 3 stars in 2025–26; its statewide rank was 1,998 of 5,804 schools, below all six nearby Carlsbad Unified schools’ percentiles. The 2024–25 student-teacher ratio was 20.2, compared with 23.7 across nearby schools. Jefferson’s 2024–25 free/reduced lunch eligible rate was 54%, above all six nearby Carlsbad Unified schools. SchoolDigger’s subgroup rankings also show notable shifts: English Language Learner Students moved from the 77th percentile in 2021–22 to the 19th in 2022–23 and 49th in 2023–24, while Special Education Students rose from the 47th percentile in 2023–24 to the 78th in 2025–26. These rankings describe results for each group, not students’ abilities.
