Retired Millicent High School principal John Shelton has nominated to replace Councillor Moira Neagle as the Corcoran Ward representative on Wattle Range Council.
He ended a record 18 years at the helm of the school at the end of 2021 and lives in retirement in Millicent.
The other candidates are Penelope Henley, Shaun Taliana and Joel McLure.
Nominations closed at noon on Thursday and a postal ballot will be held next month.
Ballot papers will be posted out by the Electoral Commission from February 14 and must be returned by March 12.
The counting of ballots will commence the following day.
Wattle Range Council already has two retired school principals among its 11 elected members in Crs John Drew and Dale Price.
Mr Shelton trained to be a teacher at Salisbury Teachers College in suburban Adelaide in the 1970s and his subsequent career as a teacher was spent entirely in country South Australia.
His classroom career began in 1979 with a two-year posting to remote Cook on the transcontinental railway on the Nullarbor Plain.
The next posting was to Streaky Bay Area School on Eyre Peninsula and was followed by eight years as the science coordinator at Kangaroo Inn Area School.
Mr Shelton was promoted to be MHS assistant principal in 1999 and then its principal in 2004.
Away from his school duties, Mr Shelton has been active in the local community and is a past president of the Millicent Lions Club and board member of the now-closed Millicent and District Community Club.
Ms Henley moved to Millicent from interstate a few years ago.
She attended a recent candidates briefing in Millicent as well as the January monthly council meeting.
There are currently only three females among the 11 current council members and just one female among the top four administrative positions.
Ward councillors at Wattle Range Council currently receive $15,381 per annum as well as up to $300 per annum for an internet connection.
Wattle Range Council anticipates the election expenses will be at least $15,000.
