Summary:
Zip code 83687 (Caldwell, Idaho) is home to just one middle school—Sage Valley Middle School—which serves 886 students in grades 6 through 8 within the Vallivue School District. As the only middle school in the area, Sage Valley's performance defines the local benchmark, and the overall picture is mixed. The school currently earns 2 out of 5 stars and ranks in the 30th percentile of Idaho middle schools, a steady decline from the 49th percentile and 3-star rating it received just two years ago.
Academically, English Language Arts is a relative strength. Sage Valley's ELA proficiency rate is 51.7%, above the district's 50.3% but slightly below the state's 54.0%. Math is the more significant concern: only 33.1% of students are proficient, compared with 34.7% in the district and 43.1% statewide—a nearly 10-point gap. Encouragingly, both subjects show steady improvement as students advance: math climbs from 30.0% in 6th grade to 35.4% in 8th grade, and ELA rises from 49.7% to 53.2%. In fact, 8th-grade math proficiency is 5.6 points higher than the district's 8th-grade average, suggesting a stronger upper-grade math program. In 8th-grade science, the school's 36.3% proficiency outpaces the district's 32.8% but trails the state's 42.9%.
Despite these bright spots, the school faces notable challenges. Chronic absenteeism stands at 20.7%, roughly 50% higher than the state rate of 13.8% and nearly identical to the district's 20.1%—meaning about 1 in 5 students is chronically absent. The free/reduced lunch rate of 39.39% indicates that 4 in 10 students come from economically disadvantaged households. Sage Valley also saw year-over-year proficiency declines in both math (-1.2 points) and ELA (-3.4 points), which helps explain its falling statewide rank. For parents, the key takeaway is a school with solid ELA instruction, improving upper-grade performance, and a supportive district context, but real gaps in math achievement and attendance that deserve attention.
