Jason Elmer Hammond, The school law of Michigan — Chapter VI: Teachers (1895 | portal)
“ The general policy of the school law is that schools shall be taught by qualified teachers, but necessities may arise where this cannot be done. A district may be unable to find a qualified teacher. Where the employment of an unqualified teacher is a necessity, the school district is authorized to employ one who has not the proper certificate, (if the school board is satisfied that the teacher is otherwise qualified) , and to pay such teacher out of the moneys belonging to the district ”
