In my district (small 3A for reference), the central office has:
1 HR Director...not sure what they do,
1 Assistant HR Dir...all they do is run background checks
1 Assistant HR Dir...for payroll
1 Assistant HR Dir...for Direct Deposit
1 Assistant HR Dir...Title IX compliance
1 Assistant HR Dir...FERPA compliance
1 Assistant HR Dir...for insurance
1 HR Secretary...I think she's really the one doing all the work.
Did I mention we're a small 3A? Anyway...
1 Director for Accounts Payable...who only acts on POs or cuts checks on the first Tuesday of the month
1 Director for Accounts Receivable
5 PR Directors (Spin Doctors)
3 IT guys...these guys actually aren't in the central office often...they are actually out in the schools doing their jobs, and they're good at it.
1 CFO...who is supposed to keep the budget balanced
1 Assistant CFO...who corrects the CFO's bad numbers, especially whenever there's an audit.
1 Curriculum Dir...Elementary
1 Curriculum Dir...Secondary
(Now...this split in jobs is the only one to me that actually makes sense.)
There's still about 6 more people, not counting the superintendent and his secretary, that work at central...but I have no idea what they do. Dir of Transportation is in the bus barn, and the Head of Maintenance is at the high school.
