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
