Summary:
Mosaics Public School Inc. contains just one elementary school, Mosaics Public School, a K–8 campus in Caldwell, Idaho, enrolling 527 students and serving a community where about 45% of students qualify for free or reduced-price lunch.
Because it is the only elementary school in the district, the school’s performance mirrors the district’s. Mosaics Public School’s strongest subject is math: 49.2% of students scored proficient in 2025-2026, which is 6.1 points above the state average. The school beats the state in math in five of six tested grades, with 7th graders leading the way at 53.7% proficiency (+10.1 points). English Language Arts is the main concern, with an overall proficiency of 50.2%, about 3.8 points below the state. The 8th grade gap is the largest at -5.9 points. Science remains slightly above average (43.8% vs. 42.7%), but the school saw a notable drop from 53.1% the previous year. Attendance is a positive indicator: chronic absenteeism is 13.0%, just below the state’s 13.8%.
The school’s state rank history has been stable, hovering around the 38th–47th percentile over the past three years, with a 2-star rating each year. Its K–8 configuration makes it more like a middle-grades school than a traditional elementary, and grade-level data should be viewed with that in mind. The student-teacher ratio is 19.2, which may mean larger class sizes. Overall, Mosaics Public School is a mid-range Idaho school with clear strength in math, a need for improvement in reading and writing, and a recent science decline worth monitoring — but attendance and math performance give parents solid reasons for optimism.
