The school ranks 11th out of 563 Utah elementary schools for 2025–26, placing it in the 98th percentile and earning a 5-star rating. Its performance has been consistently strong: it has ranked among Utah’s top schools for six consecutive reported years, improving from the 35th percentile in 2015–16.
