Summary:
ZIP code 85648 has one middle school, Coatimundi Middle School, serving grades 6–8 in the Santa Cruz Valley Unified District. In 2025–2026, 36% of students were proficient in ELA, compared with 41% statewide, while 19% were proficient in math, compared with 33% statewide; 8th-grade science proficiency was 14%, versus 30% statewide in 2024–2025. The main concern is math, especially in the two upper grades, where proficiency was far below state results.
Because Coatimundi is the only school in the list, it is technically both the highest- and lowest-scoring school, but that is not a meaningful school-to-school comparison. The clearest bright spot is 6th-grade math: 33% proficient, 3 points above the state rate. By contrast, 7th-grade math was 13% versus 27% statewide, and 8th-grade math was 13% versus 30%. ELA results were closer to state rates: the school was 8 points behind in 6th grade, 2 points behind in 7th, and 6 points behind in 8th. This makes the school’s upper-grade math results its sharpest area of concern, while ELA is comparatively nearer to state levels.
SchoolDigger gives Coatimundi 2 stars and ranks it 348th of 536 schools, at the 35th percentile. Its percentile ranking dipped from 36 in 2023–2024 to 30 in 2024–2025, then rebounded to 35 in 2025–2026—5 points up from the prior year but 1 point below its earlier standing; this ranking history does not establish a test-score trend. The school reports 497 students and a student–teacher ratio of 23.1, while no free/reduced-lunch rate is provided. Since the list contains only one school and ELA and math results are available for just one year, these data cannot show how schools compare across the ZIP code or whether test scores are improving over time.
