The superintendent's
HR office does most of the vetting and
placing, but it is shackled by the contract, by state licensure practices (which may be set by an «independent» — and probably union and ed - school dominated — professional - standards board), by seniority rules that are probably enshrined in both contract and state law, and by uniform salary schedules that mean the
new teacher (assuming similar «credentials») will be paid the same fixed amount whether the subject most needed
at Lincoln is math or music.
