Summary:
Mabton Junior Senior High is the only high school in Mabton School District, serving grades 7–12 and about 359 students in Mabton, Washington. The school has an 18.1-to-1 student-teacher ratio, and 92.76% of students qualify for free or reduced-price lunch, indicating substantial economic need in the community. Because it is the district’s only high school, there are no other local high schools for direct comparison.
The school’s clearest strength is graduation: 91% of students graduated in 2024–2025, compared with 82.6% statewide. The reported dropout rate was 7.6% in 2023–2024, and the school’s statewide ranking has improved in recent years. Academic test results, however, remain much lower than Washington averages. In 2025–2026, 25.69% of students were proficient in English language arts, 11.19% in math, and 16% in science. These results were approximately 27, 32, and 35 percentage points below the state averages, respectively. Math is the most urgent academic concern, while science was slightly stronger than the district result.
There are some encouraging signs. Proficiency increased from the prior year in all three subjects, with English language arts showing the largest gain. Tenth-grade English language arts was a relative bright spot, with 40% of students proficient, compared with 20% in seventh grade and 14.29% in eighth grade. Parents may want to consider both sides of this profile: the school appears effective at supporting students through graduation, but many graduates may need additional preparation in core academic skills. With reported spending of $21,091 per student, useful questions for families and the community include how resources support math and science instruction, tutoring, student counseling, attendance efforts, and preparation for college, career, or technical education.
