West Gresham Elementary School

Our son attends West Gresham Elementary.
Our son has been constantly harassed and threatened many times over the last school year. We have complained and even coached him to ignore the name-calling, racism, and harassment. After today's incident, we are filing a police report.
#1
Most recent incident occurred 10/30/19 3:00-3:20pm (Bus drop off home)
We called at 530pm and left a message on the school line.
He had an incident with the Caucasian woman, bus monitor on his ride home from school.
He is a self-manager, which grants him the duty of being a bus monitor.
According to what I was told is as followed:
My son stated that he was doing his normal bus duties to make sure the kindergartens were seated. This lady grabbed his armed and told him to sit down and she was going to put him to the front of the bus. He pulled away and explained that he was making sure the little kids were in their seats.
Upon exiting the bus she made a comment "Black kids these days"

1 week ago he was pushed into the mud by a kid that was bullying him.

#3 - School has a record of this
4 weeks ago he was hit on the head (Kid slammed the door) in his face and he fell to the ground. An incident report was filed, I was contacted by the nurse. However, this child was upset because my son was chosen to be self-manager by the teacher.

#4 - School has a record of this
In the Spring (I believe it was April/May), he threatened to have his throat slit by another child. The school filed a police report but I did not press charges at that time.
#5
Almost daily he was bullied and called racism & homophobic names on and offsite school premises. It occurred so often we honestly stop keeping track because we had no physical proof, as parents we could only provide him emotional support.

We are requesting the policy and process necessary to escalate this matter of safety and concern. We are requesting the school district investigates the West Gresham school of racism and safety for my African-American child, as if they do not want him there then the district needs to transfer him to a school that is more diverse in educating diverse children.
