Results declined at all three schools from 2024–2025 to 2025–2026, even as the state improved in each subject. The area’s average fell by less than a point in ELA, 4 points in math, and 2 points in science; the Charter Academy’s math score had the largest school-level drop, 7 points. SchoolDigger’s ranking percentiles also fell between 2023–2024 and 2025–2026: from 80 to 75 for Franklin, 86 to 74 for Cosumnes Oaks, and 45 to 33 for the Charter Academy. The Charter Academy is smaller (262 students) and has a lower student-teacher ratio (19.2) than Franklin (2,650; 23.5) or Cosumnes Oaks (2,109; 21.4), but that does not coincide with higher proficiency in these results. All three report free/reduced lunch eligible figures for 2024–2025: 57% at the Charter Academy, 40% at Franklin, and 39% at Cosumnes Oaks. Because the Charter Academy serves younger grades than the other two schools, all-grades comparisons are not perfectly like-for-like.
