SchoolDigger’s percentile rankings show different recent trends: Nautilus scored 60, 55, and 55 from 2023–24 through 2025–26, while Havasupai fell from 47 to 35 to 25. The two-school average ranking declined from about 54 to 40, a 14-point drop; these rankings reflect relative standing, not changes in proficiency. Enrollment and student–teacher ratios are similar—345 students and 19.1 to 1 at Nautilus, versus 324 students and 19 to 1 at Havasupai—so those figures do not mirror the achievement gap. Havasupai grade 5 ELA and grades 3 and 6 math results are suppressed, and both schools’ free/reduced-lunch fields are blank.
