Enact district-wide discipline codes.
Most school districts have a formal discipline policy.
In some cases, the district policy spells out those behaviors considered unacceptable and consequences for infractions of the rules. In other cases, the district-wide policy only requires individual schools to establish a discipline code. Allowing each school to establish it's own code is far less effective than having a district-wide policy. Staff, parent and community representatives, and students should serve on the committee developing the code. The code itself should specify methods to keep parents involved with the discipline of their children.
