Any school administrators or those that require administration features (key features detailed here) and do not exist in Clever will need to be added directly through Clever. Once the admins are added to Clever through the district's Clever account, Next Gen Math will automatically sync with their accounts.
See Clever Roles: Staff - How to add to Clever on Clever for more.
We recommend giving school site specialists and/or intervention teachers without a classroom staff/admin access to the program.
NOTE
Next Gen Math does not internally create or manage administrator accounts when syncing through Clever. Any administrators that need access must be added through Clever as detailed above.
