Summary:
Marmaton Valley Elementary is the only elementary school listed in Marmaton Valley, serving PK–5 and enrolling 134 students. Its strongest overall results are in science and math: in 2025–26, proficiency was 64% in science and 62% in math, compared with 38% and 41% statewide; ELA was closer to the state, at 47% versus 46. The most important finding is that the school’s strong science and math results contrast with a much more uneven ELA picture.
The school stands out most for science and math, but fifth-grade ELA is its clearest weak spot. All-grades proficiency was 26 points above the state in science and 21 points above in math, while its ELA advantage was just 1 point. Within grades, fifth-grade ELA proficiency was 36%, 15 points below the state’s 51%; third- and fourth-grade ELA were above state results. Math varied by grade: fourth- and fifth-grade proficiency was 71% in each grade, respectively 27 and 26 points above state rates, while third-grade math was 37%, 6 points below the state. Because there is only one school in the list, there is no school-to-school top or bottom comparison.
Recent results show different directions by subject: the school’s advantage over the state narrowed in ELA and math but widened in science. From 2024–25 to 2025–26, ELA fell from 51% to 47%, while the state rose from 44% to 46%; math edged up from 61% to 62%, but the state gained faster, while science rose from 62% to 64% as the state fell from 41% to 38%. SchoolDigger ranked the school 221st of 657 statewide in 2025–26, at the 66th percentile with three stars; it was at the 69th percentile in 2024–25 and 56th in 2023–24. Its student–teacher ratio was 10.7 in 2024–25, and 67% of students qualified for free or reduced-price lunch, a measure of school context rather than an explanation for results. The available data do not allow comparisons with similar schools.
