School and District features are part of Edmodo Management, one of your premium packages. The only difference between School and District features is the scope of users they are intended to reach. Both School and District features offer:
District Accounts should be maintained by a tech director, curriculum director, or similar administrator at the district level. The district admin must be able to view and assist all users within the District Account. Within a District Account, school admins can be given visibility to their school only. All users in the district will login through the same district page. The district admin will be able to view all users at the district and filter them by individual school.
School Accounts should be maintained by a tech coordinator or similar administrator at the school level. The school admin must be able to view and assist all users within the school network. There is only one level of administrator in a School Account.
