Summary
Arthur S. Dudley Elementary serves 521 students in grades K–6 in Antelope, California, and is part of Center Joint Unified. SchoolDigger places the school at the 16th statewide percentile and gives it 1 star for 2025–26, below the district’s 33rd percentile and 2 stars. The most important finding for families is that Dudley’s proficiency was below both state and district results in ELA, math, and science, with ELA the clearest weakness.
Math is Dudley’s strongest subject compared with the state and district, while science is closest to nearby K–6 peers. In 2025–26, Dudley’s proficiency was 22% in math, compared with 38% statewide and 27% in the district; in science, it was 17%, versus 36% statewide and 27% in the district. ELA was 25%, compared with 49% statewide and 38% in the district. The five nearby K–6 schools averaged 35% in ELA, 27% in math, and 19% in science, putting Dudley 10, 5, and 2 percentage points below those averages, respectively. Among the six K–6 schools, including Dudley, its ELA result was second-lowest, math lowest, and science third-lowest.
Results have risen over the four supplied years, especially in math, but remain well below state levels: from 2022–23 to 2025–26, Dudley’s proficiency increased by 5 percentage points in ELA, 9 in math, and 7 in science, while the gaps with the state narrowed by 2, 5, and 1 point, respectively. Chronic absenteeism also fell, from 49% in 2021–22 to 25% in 2025–26, though the latest rate remained 6 points above the state and 2 above the district. Context includes a 24.8 student–teacher ratio in 2024–25—the highest among nearby schools with data—and a free/reduced lunch eligible measure of 72% in 2024–25, around the middle of nearby schools with that measure. SchoolDigger’s English Language Learner Students percentile swung from 2 in 2021–22 to 39 in 2022–23 and 14 in 2023–24, compared with Dudley’s overall percentiles of 17, 8, and 14, indicating substantial year-to-year variation in its relative measure of how well it serves that group. For African American Students, the subgroup percentile also shifted, from 24 in 2023–24 to 9 in 2024–25 and 22 in 2025–26, versus overall percentiles of 14, 14, and 16.
