Summary:
Mendon, Utah, has one public school, Mountainside School, serving about 514 students from pre-K through sixth grade in the Cache District.
Because Mendon has only one school, there are no local school-to-school comparisons; the most useful context is how Mountainside School compares with its district and Utah overall. The school has ranked in roughly the top 20% of Utah schools during each of the past three reported years, although its ranking declined from 46th in 2024–2025 to 107th in 2025–2026. It remains part of a strong district, with the Cache District ranked 16th of 92 districts statewide. Mathematics is the school’s most consistently strong subject: proficiency was above the Utah average in every tested grade, averaging about 64%, compared with roughly 46% statewide. Science was also strong overall, especially sixth grade, where 84.8% of students were proficient.
Performance varies by grade, so parents may want to look beyond the overall ranking. Sixth grade was a clear standout, exceeding district and state results in English language arts, mathematics, and science. Fourth-grade English language arts was the main weakness, with 43.3% proficient, and fourth-grade science also trailed the district average. Fifth-grade mathematics and science results dropped notably from the prior year, while sixth-grade science improved. Chronic absenteeism was 19.7%, better than Utah’s 23.8% but higher than the district’s 16.3%, making attendance an area worth monitoring. Overall, Mountainside School appears to offer strong academic performance, particularly in mathematics and upper-grade science, with the greatest opportunities for improvement in fourth-grade literacy and science, fifth-grade consistency, and attendance.
