Taylion High Desert Academy/Adelanto

Taylion High Desert Academy/Adelanto is an alternative K–12 school in Adelanto, California, with 803 students. Its 2024–25 proficiency results were below California’s in all three tested subjects: 20% in English language arts (ELA), 10% in math and 13% in science, compared with 49%, 37% and 33% statewide. The most serious concern is the latest supplied graduation and dropout data: in 2023–24, 38% of students graduated, versus 86% statewide, while 39% dropped out, compared with 9% statewide.

Compared with 10 nearby schools, Taylion’s ELA result is its clearest weakness: 20% was 8 percentage points below the group average of 28%, and ranked eighth-lowest among the 11 schools. Math and science were closer to nearby averages—10% versus 11% in math, and 13% versus 16% in science—with Taylion around the middle in both subjects. Its results were below California’s by 29 points in ELA, 28 in math and 20 in science, making science its strongest subject relative to the state. For context, High Desert Premier Academy scored lower than Taylion in all three subjects, while Academy for Academic Excellence scored higher in all three. The supplied data do not include a district test benchmark or a SchoolDigger rank or star rating.

Math shows the clearest improvement over time: it rose from 3% in 2022–23 to 10% in 2024–25, and its gap with the state narrowed by 4 points. ELA and science each gained about 3 points overall, but their gaps with the state changed little. Chronic absenteeism improved substantially, falling from 56% in 2022–23 to 18% in 2024–25—1 point below the state rate that year. As context, the school’s student-teacher ratio was 23.8 in 2024–25, the third-highest among the 11 nearby schools, and its enrollment was the fourth-largest. Taylion reported that 80% of students were free/reduced lunch eligible in 2024–25, 6 percentage points above the nearby-school average; these measures describe context, not the cause of results.
