Summary

Rimrock Elementary is a PK-6 school in Ammon, ID, serving 533 students in the Bonneville Joint District, and it currently ranks as one of the strongest elementary schools in the state at 43rd out of 346 Idaho elementary schools (88th percentile, 4 stars). Rimrock's academic results far exceed both its district and the state: math proficiency sits at 65.2% compared to the district's 41.4% and the state's 43.1%, while English language arts proficiency reaches 71.1% versus the district's 54.9% and the state's 54.0%.

Among nearby schools, Rimrock Elementary is the clear leader in overall math and ELA. Woodland Hills Elementary is its closest academic peer at 61.6% math and 70.0% ELA, while Iona Elementary trails further at 52.3% math and 65.3% ELA. The contrast is even more striking with Mountain Valley Elementary, located just 0.84 miles away, which posts 36.2% math and 44.7% ELA. Rimrock also stands out for very low chronic absenteeism at 7.9%, compared to the district's 13.4% and the state's 13.8%, and a relatively low free/reduced-price lunch rate of 13.7%. Several nearby schools face much higher economic disadvantage indicators, such as Hillview Elementary at 62.8% and Tiebreaker Elementary at 62.3%.

Rimrock achieves these results with remarkable efficiency: per-student spending is $5,692 with a 22.9 student-teacher ratio, while several lower-performing nearby schools spend more and have smaller class sizes. The school has been consistently high-performing for a decade, ranking between the 79th and 91st percentile every year since 2015-2016, with strong outcomes across both female and male student subgroups. The main areas to watch are 5th grade math (53.9% proficient) and science, where Woodland Hills currently posts stronger results — but Rimrock remains the strongest overall elementary school in this part of Ammon.

What people are saying

by a teacher
Thursday, September 26, 2019

I was a teacher at Rimrock at one point in the past and had a very mixed experience.

The Good
Overall students at this school are from high functioning families and are quiet bright. This made teaching easier then in some areas I've taught.
The Bad
While there are some very nice students and families at Rimrock there are also some very entitled "snowflakes" whose parents will throw a fit if their kid makes a B not an A.
The former principal (Mrs. Orme) was unprofessional and incompetent. I believe she is now at a new school where I expect things will quickly fall apart. I witnessed discipline and grades in several classrooms go down because a small number of students were allowed to misbehave with no consequences. I don't mean kids being kids. I witnessed students leaving class and roaming the hallways for extended periods of time with no consequences. Kids who get phones out (which they were not supposed to have) and call their parents to come see them because they were "stressed" in school. Parents would then come back and ask teachers what was going on. An older boy threatened to punch the playground aid with no consequences. Kids plagiarized assignments and when I gave them a low grade Orme changed their grade without my knowledge. On the other hand Orme would come across the school into my room to fuss at boys who talked too loudly in the hallways. Needless to say I moved on to a new place where I'm much happier. Close Quote
