Best Elementary Schools in Zip Code 83610

Zip code 83610 (Cambridge, Idaho) is served by a single elementary school, Cambridge Elementary School, which enrolls 75 students in grades PK–5 within the Cambridge Joint District. Because this is the only elementary school in the area, the focus is entirely on how this small rural school compares to district and state averages.

Cambridge Elementary School stands out for its strong math performance and personalized learning environment. In 2025-2026, 66.7% of students were proficient in math, well above the district’s 48.1% and the state’s 43.1%. With a student-teacher ratio of just 9.3 and an enrollment of 75, class sizes are very small, and per-student spending reached $21,265 in 2018-2019—reflecting the higher costs of running a rural school. Chronic absenteeism is also a bright spot at 9.4%, better than the district’s 10.3% and the state’s 13.8%, suggesting strong attendance and family engagement. While 56% of students qualify for free or reduced-price lunch, the school still posts strong math scores, indicating effective instruction in that subject.

However, English language arts is a concern. The school’s ELA proficiency rate dropped sharply from 63.6% in 2024-2025 to 47.2% in 2025-2026, falling below both the district (49.4%) and state (54.0%). This decline is notable since math only slipped by 3 points over the same period. Grade-level data shows some bright spots: 4th grade math (53.8%) and 5th grade science (57.1%) both beat state averages, while 5th grade ELA (57.1%) is above the state’s 55.2%—suggesting younger students may be struggling more with reading and writing. Historically, the school’s state ranking has been volatile, swinging from the 27th percentile in 2011-2012 to the 97th in 2012-2013, then settling at the 66th percentile in 2025-2026. This variability is common in very small schools, where a handful of students can shift results dramatically. Overall, Cambridge Elementary School offers strong math instruction, good attendance, and a caring, small-school atmosphere, but families should be aware of the recent drop in ELA proficiency.
