Summary:
Zip code 66440 has two listed schools in the Royal Valley district: Royal Valley Elementary serves prekindergarten through grade 4 and enrolls 369 students, while Royal Valley High serves grades 9–12 and enrolls 223; no middle-school grades are listed. Because the schools serve different grades, their all-grades results are not direct school-to-school comparisons. The clearest concern is math: every listed grade is below its state benchmark, with third-grade math at 34% compared with 43% statewide, an 8-point gap.
Royal Valley Elementary has the strongest listed result: fourth-grade ELA reached 55%, 5 points above the state’s 50%. Its third-grade ELA was 48%, 3 points below the state, while fourth-grade math was 37%, 7 points below. Royal Valley High was closest to a state benchmark in 11th-grade science, at 27% versus 30%, a 3-point gap; its 10th-grade math was 33% versus 37%, 4 points below. High’s 10th-grade ELA was 36%, 4 points below the state’s 41%. Overall, Elementary’s fourth-grade ELA stands out at the top, while its third-grade math is furthest below its grade-specific benchmark.
Recent all-grades trends are mixed: Elementary’s ELA rose 9 points, from 43% to 52%, while High’s fell 2 points, from 38% to 36%; math rose 1 point at Elementary and 6 at High. Compared with statewide all-grades changes, Elementary’s ELA position improved by 7 points and High’s worsened by 4, while both schools improved their relative math positions. SchoolDigger’s ranking history also differs: High fell from the 83rd percentile in 2023–24 to the 38th in 2025–26, while Elementary rose from the 36th to the 40th percentile. Elementary’s student-teacher ratio is 12.6 and its free/reduced-lunch rate is 54%; High’s ratio is 9.3 and its rate is 38%. These are useful context, not explanations for the schools’ results.
