Summary
Lone Tree Elementary serves 518 students in grades K–5 in Antioch, within Antioch Unified. The most important finding for families is that its 2025–26 proficiency rates were below California’s in every subject: 27% in English language arts (ELA) versus 49% statewide, 17% in math versus 38%, and 19% in science versus 36%.
Locally, Lone Tree’s results are mixed: ELA was nearly level with the district, while math and science were modestly higher. Its rates were 27% in ELA compared with 28% for the district, 17% in math compared with 16%, and 19% in science compared with 17%. Against nearby schools, however, Lone Tree was below the average in all three subjects: 31% in ELA, 23% in math, and 20% in science. Math is its strongest subject relative to the district and nearby schools, while science is closest to the state rate; ELA is its weakest relative to the district. Third-grade ELA stands out as a concern at 18%, compared with 31% in grade 4 and 31% in grade 5. Nearby schools have different grade spans, so the all-grades comparisons are useful context rather than exact matches.
Scores have edged up since 2022–23, but all three subjects fell in the latest year: over the full period, ELA gained 3 percentage points, math 2, and science 1, while the 2025–26 results dropped 4, 4, and 3 points, respectively, from the year before. Chronic absenteeism improved from 46% in 2022–23 to 31% in 2025–26, yet remains above the state’s 18%. SchoolDigger ranked Lone Tree in the 13th percentile statewide in 2025–26, with 1 star and a rank of 5,074 out of 5,804; its percentile fell from 21 the prior year. Its 2024–25 student–teacher ratio was 20.3, below the nearby average of 21.5, and 73% of students were free/reduced lunch eligible that year. SchoolDigger’s subgroup rankings show stronger statewide standing for African American students (47th percentile in 2025–26, versus 13th overall) and a sharp decline for Special Education Students (5th percentile, down from 43rd the prior year).
