Iowa Code § 274.2: General applicability.

The provisions of law relative to public or accredited nonpublic schools shall apply alike to all districts, except when otherwise clearly stated, and the powers given to one form of corporation, or to a board in one kind of corporation, shall be exercised by the other in the same manner, as nearly as practicable. But school boards shall not incur original indebtedness by the issuance of bonds until authorized by the voters of the school corporation.
