Summary:
Ammon, Idaho, is served by 8 schools — 6 elementary schools, 1 high school, and 1 alternative K–12 charter school — that together enroll 4,224 students, with no standalone middle school in the city. Six schools belong to the Bonneville Joint District, while White Pine Charter School and Monticello Montessori Charter School operate as their own districts. The elementary landscape is deeply divided: Rimrock Elementary ranks in the 88th percentile statewide with 65.2% math and 71.1% ELA proficiency, while Woodland Hills Elementary ranks in the 84th percentile with 61.6% math and 70.0% ELA proficiency.
These two schools stand far above the rest. Hillview Elementary School, Mountain Valley Elementary School, and Ammon Elementary School all fall below state averages in math and ELA, with Hillview posting the highest poverty rate (62.8%) and highest chronic absenteeism (21.7%) in the city. Monticello Montessori Charter School has the lowest absenteeism (5.8%) but the weakest academics overall, ranking in the 22nd percentile. Hillcrest High School, the only traditional high school, shows mixed results: strong End-of-Course ELA (69.8%) but below-average math (32.2%), and its ranking has swung dramatically between years. White Pine Charter School offers a solid alternative with strong science proficiency (51.9%) despite serving a higher-poverty population.
Poverty and absenteeism track closely with achievement across Ammon, while per-student spending does not: the two highest-performing elementary schools spend the least per student (based on 2018–19 data). Hillcrest enrolls 29% of all Ammon students, and grades 7–8 students in the Bonneville district must attend schools outside city limits or enroll in one of the two charters that serve middle grades. Overall, families in Ammon will find two excellent elementary options in Rimrock and Woodland Hills, a large and somewhat inconsistent high school in Hillcrest, and charter alternatives that offer different structures but mixed academic results.
