I went to Century Middle School for 7th & 8th grade, and I would not recommend this school to anyone. Ask any of the previous students.

I really enjoyed Century Middle School while I was there from 6th-8th grade. Every school had its ups and downs, but the teachers and staff without a drought are amazing. They are always working with you and help when needed. To be fair, some may say they don't like it, but mainly because of the students. People are going to mean no matter what and you can't stop that. But I give the school a 5 star reviewed because my experience was just amazing. Thank you :)
