Summary

Southside Elementary School is a small, rural PK-6 school in Cocolalla, Idaho, serving 170 students in the Lake Pend Oreille School District. The school holds an impressive position in Idaho, ranking 61st out of 346 elementary schools and earning a 4-star rating for 2025-26, placing it in the 82nd percentile. This top-quartile status is reinforced by a history of strong performance, including a 5-star rating in the early 2010s and a peak rank of 21st in 2012-13. Within the district, only Washington Elementary School and Northside Elementary School rank higher, placing Southside firmly in the district’s top tier.

One of Southside’s defining strengths is mathematics, with an all-grades proficiency rate of 62.9% — well above the district’s 54.1% and the state’s 43.1%. Sixth-grade math is particularly strong at 72.4%, far exceeding district and state averages. Science is another standout: 5th-grade proficiency hits 66.7%, compared to just 44.0% statewide. In both subjects, Southside comfortably outperforms its closest geographic neighbor, Sagle Elementary School, which posts a 39.5% math proficiency rate. The school also maintains a low chronic absenteeism rate of 8.0% (2021-22) versus the district’s 18.0%, a factor that likely contributes to its academic success.

Despite serving a growing population of economically disadvantaged students — with the free/reduced-price lunch rate rising from 34.4% to 42.9% over three years — Southside has seen math proficiency improve markedly, from 46.5% in 2023-24 to 62.9% in 2025-26. This is achieved even with a relatively high student-teacher ratio of 18.1 and per-student spending below some lower-performing peers. The main area for attention is early literacy: 3rd-grade ELA proficiency stands at 50%, below the district average of 54.6%. However, upper-grade ELA scores are solid, suggesting students make gains after 3rd grade. Overall, Southside delivers strong results through effective instruction and a positive school culture, making it a compelling choice for families in the Cocolalla area.
