I've been to Wapato Middle School and Wapato Adams Elemenary (I'm in 8th) and so far I don't see why people think Wapato is a bad community. Sure we aren't the best school out there, every school has its problems. All we can do is try right? Wapato is based on cultures. Lots and lots of them. They have many programs available for any type of student. No lie. Sure we're not the best at everything. But the teachers are dedicated to helping students in every way they can. THEY ACTUALLY MOTIVATE THE KIDS!!! I don't believe people should judge a book by its cover. Or in this case, a school by a few bad students.

This school is a joke. They treat your child like cattle. They allow gang activity and bullying to happen right in front of them. My child has only been with this school for 3/4 of the school year and they allowed for my child to be attacked and gang threatened by another student and acted as if it was no big deal. The Principal and Vice principals were extremely defensive and acted as if this situation was my child's fault. If you don't want your child bullied do not send them to this school.

Clarkston is a hidden gem among the elementary schools in Tyler ISD. They have such a dedicated staff that truly cares about each and every child. With enhanced technology in every classroom and a multitude of enrichment opportunities, it is a wonderful place. The new campus is amazing.

Administration is stubborn and lacks the ability to listen.
