You may have received the proposal because:
the initiator of the proposal identified your department as a unit impacted by the proposed change.
the course involved in the proposal may be bundled with a course from your department.
In both cases, you should review the proposal and select Approve to move it forward in workflow if you have no questions about its content.
If neither of the above is true and the proposal is not for your department, contact your college catalog contact to review your role assignment.
