Summary:
Zip code 37339, covering the Gruetli-Laager area of Tennessee, contains exactly one public school: Swiss Memorial Elementary School, a PK–8 campus with 317 students serving as the community's sole elementary and middle school provider.
As the only school in the zip code, Swiss Memorial Elementary is the automatic focal point. It functions as a combined elementary and middle school under the Grundy County Schools district, which ranks 106th out of 141 Tennessee districts (25th percentile). The school's own statewide ranking has slipped from the 35th percentile (2 stars) in 2023–2024 to the 25th percentile (1 star) in 2025–2026, reflecting declines in most subjects. However, there are notable bright spots: 8th grade math proficiency reached 46.5%, above both the district (35.6%) and state (38.3%), and 6th/7th grade social studies exceeded state averages. In contrast, serious gaps exist in 5th grade ELA (17.6% vs. 42.7% statewide) and 6th grade science (23.7% vs. 48.0% statewide).
Stepping back, all-grade proficiency in 2025–2026 trails state averages across the board: math (34.7% vs. 43.0%), ELA (25.7% vs. 40.6%), science (32.7% vs. 46.9%), and social studies (44.5% vs. 51.4%). Year-over-year, only ELA improved (+2.2 points), while social studies fell sharply (-6.4), math (-2.8), and science (-3.3). Chronic absenteeism is elevated at 20.9%, exceeding both the district (16.8%) and state (18.3%). The school spends $13,437 per student, suggesting meaningful investment in a rural setting. For parents, this school offers a stable, close-knit environment covering all grades up to 8th, with proven strengths in middle-grade math and social studies—but the downward trajectory in state ranking and persistent achievement gaps, especially in early math and upper-grade science, are important factors to weigh.
