Summary

Century Alt High is a 9–12 school in Los Lunas, New Mexico, serving 353 students as part of Los Lunas Public Schools, a district ranked 63 of 87 statewide (28th percentile, 2 stars). Nearly every student is economically disadvantaged — 99.43% qualified for free or reduced-price lunch in 2024–25 — and the school's student–teacher ratio of 38.3 is the highest among nearby campuses, far above Valencia High (23.4), Los Lunas High (19.4), and Rio Grande High (12.7).

Century Alt's 2025–26 rank is 79 of 132 (40th percentile, 2 stars), a dramatic jump from 125 of 131 (5th percentile) in 2024–25 and 158 of 172 (8th percentile) in 2023–24. Proficiency in 11th-grade Language Arts (32%), science (29.17%), and SAT ELA (32%) came in above the district average and above Rio Grande High, Valencia High, Atrisco Heritage Academy High School, South Valley Academy, and Belen High, though Los Lunas High scored higher in Language Arts and SAT ELA. The graduation rate also rose sharply, from 33.0% to 53.5%.

Challenges remain substantial. Graduation, at 53.5%, is far below the district (77.2%) and state (80.6%) and lower than nearly every nearby school, including New America School (57.6%) and Belen Infinity High (62.1%); only Robert F. Kennedy Charter (51.5%) is lower. The student–teacher ratio has climbed from 27.0 to 38.3 over three years. Math proficiency is suppressed by the state, so it is unknown rather than zero, and regional math scores are low across the board. School-effectiveness ranks for female and low-income students remain in very low percentiles, so the overall gains are not evenly spread.
