Summary:
Six elementary schools serve Snowline Joint Unified: five serve kindergarten through grade 5, while Heritage serves kindergarten through grade 8. Across the schools, average proficiency was 37% in English language arts (ELA), 29% in math and 30% in grade-5 science, compared with state averages of 46%, 42% and 35%; the area averages were higher than district averages in all three subjects. The most important takeaway is that these overall figures hide large differences between schools.
Wrightwood and Heritage stand out, while Pinon Hills and Phelan have the lowest results in key measures. Wrightwood leads ELA at 60%—14 points above the state—and grade-5 science at 52%, 16 points above. Heritage leads math at 51%, 9 points above the state, and also exceeds the state in ELA (54%, 7 points above) and science (44%, 9 points above). At the lower end, Pinon Hills is at 21% in ELA, 26 points below the state, and 17% in science, 18 points below; Phelan’s 15% in math is 27 points below the state.
Recent results improved overall, especially in science, but progress was not universal: the six-school all-grades averages rose by about 1 point in ELA, 1 in math and 5 in science from 2024–25 to 2025–26. SchoolDigger rankings also show different trajectories: Pinon Hills rose 7 percentile points over three years and Vista Verde rose 5, while Heritage fell 5 and Wrightwood fell 2. Family context varies: in 2024–25, the free/reduced lunch eligible share ranged from 44% at Wrightwood to 85% at Phelan; these figures are context, not an explanation for results. Attendance also sets Heritage apart: chronic absenteeism was 8% there in 2025–26, versus 18% statewide, while the other schools ranged from 22% at Wrightwood to 31% at Pinon Hills. These school comparisons use common tested grades, and averages are not enrollment-weighted.
