(2) There is not a clearly demonstrable need and intent for it to carry out an education function.
(b) Positions established for regular school operations will be restricted to school term or program duration. Particular care shall be taken to insure that year-long positions are not established unless they are clearly required and involve essential 12-month assignments.
