Summary

Mosaics Public School is a K–8 public charter school in Caldwell, Idaho, serving 527 students and operating as its own independent district, Mosaics Public School Inc. While physically located in Caldwell, it is not part of the Caldwell District. The school ranks 187th of 346 Idaho schools, placing it near the statewide middle but well above most schools in its immediate area.

Mosaics' clearest academic strength is math: 49.2% of students scored proficient in 2025–2026, above the state average of 43.1% and roughly double or triple the proficiency rates at nearby schools like Van Buren Elementary School (30%) and Sacajawea Elementary School (19.2%). The school also has the lowest chronic absenteeism rate (13%) among all nearby comparison schools, far better than Washington Elementary School (27.8%) and Van Buren (27.1%). Hispanic students at Mosaics rank in the 74th percentile statewide, a strong signal that the school serves this group especially well.

The main area for growth is English language arts, where Mosaics' 50.2% proficiency rate trails the state average of 54% and lags the top nearby schools: Middleton Mill Creek Elementary (65.6%) and Middleton Heights Elementary (55.9%). Science is near the state average at 43.8%. Overall, Mosaics is a solid academic standout in a low-performing part of Caldwell — noticeably outperforming neighboring schools despite serving a similar population with about 45% low-income students — and its steady math improvement over three consecutive years suggests positive momentum.
