I support these critically important policies in order to protect children from inappropriate sexual content at school & respect parental rights to determine whether or not their children  are to be exposed to this type of content. 
Not only do parents have the fundamental right to make these decisions but they are in the best position to know what is appropriate for their unique children. 
Also please make sure through this document that there are specific actions that every school must take in order to ensure sexually explicit materials are correctly identified & seen by parents first. I am extremely concerned that unless certain minimum standards are spelled out & mandated, many schools will find a way around what they find as mere guidance. Please ensure the wording is clear with no exception.
