JCMS, otherwise known as Joyce Clark Middle School. Is a school located in Sierra Vista, Arizona full of complete potheads 13 year old whores, and SPED kids that still play Minecraft. The school is a complete hell hole where teachers are hired off of the streets. There are many drug dealers, and some kids even vape and smoke DURING SCHOOL! The school starts at 9 a.m. so kids can get a shit ton of sleep unless they are careless and stay up until 2 a.m. Overall the school sucks, I do not recommend you to allow your kids to go here. If your kids go here they can likely end up being drug addicts, who are not virgins at the age of 12.

JCMS is the worst school out there.
