If the joint election provided for in § 13-7-10.1 is held on the second Tuesday in April, no candidate for elective school board membership may be nominated unless the candidate is a resident voter of the school district and unless a nominating petition has been filed on the candidate's behalf with the business manager of the school district no later than the last Friday in February at five p.m. prior to the date of the election. If the petition is mailed by registered mail by the last Friday in February at five p.m. before the election, it shall be considered filed. A formal declaration of a candidate shall be signed by the candidate before the circulation of the petition. The petition shall be signed by not less than twenty voters of the school district. No petition may be circulated until the last Friday in January before the election. There shall be added by either the signer or the circulator the signer's place of residence and date of signing. The petition shall be verified under oath by the person circulating the petition. The filing of the nominating petition shall constitute nomination and will entitle the candidate to have the candidate's name placed on the ballot for the term the candidate specifies on the petition only upon verification signed by the business manager that the nominating petition contains the minimum number of signatures and that the candidate is a resident voter.
Publication of the notice of the election provided for in § 13-7-10.1 shall be in accordance with § 13-7-8.
