SchoolDigger Rank ?

of 5,817 California Alternative Schools

Summary

Mojave River Academy - Marble City is an alternative K–12 school in Phelan, California, with 259 students. Its most serious concern for families is that proficiency in English language arts (ELA), math, and science is below the California average in the 2025–2026 results.

Compared with nearby schools, the school is relatively stronger in science and math than in ELA: it ranks third of six in science and math, and fourth of six in ELA. Its proficiency rates are 13% in science, 6% in math, and 19% in ELA, compared with nearby-school averages of 12%, 6%, and 24%, respectively. Against the state, the gaps are 23 percentage points in science, 33 in math, and 30 in ELA. Attendance is a bright spot: chronic absenteeism was 11%, below California’s 18%. Graduation is a concern, however: the 2025–2026 rate was 67%, the second-lowest among five nearby schools with results. The supplied information has no district test results or the school’s SchoolDigger statewide rank and stars, so those comparisons are unavailable; the Mojave River Academy - Marble City District therefore cannot be compared on test scores here.

Results over time show some improvement, but not a consistent narrowing of the state gaps. Math proficiency rose from 2% in 2022–2023 to 6% in 2025–2026, while ELA shifted from 20% to 19% and science from 11% to 13%. Graduation fell from 91% in 2021–2022 to 67% in 2025–2026, a 24-point decline. Context for families: the student–teacher ratio was 23.7:1 in 2024–2025, the second-highest among nearby schools with data. In that same year, 81% of students were eligible for free/reduced lunch, a measure that describes the school’s student population but does not explain its results.
