The Clay Community School (CCS) board members voted to fill the vacant seat left after a member resigned in June.
On Thursday, the board voted 4-0-1 in favor of replacing Dottie King with Tammy Beasley.
The board interviewed three candidates to replace King Tuesday.
Board member Forrest Buell was unable to cast a vote on the motion while board member Ron Scherb said because he did not attend the interview sessions, he would abstain from voting.
Board member Tina Heffner motioned in favor of Beasley with Amy Adams giving the second.
Beasley was sworn in by Clay Circuit Court Judge Joe Trout.
The other residents the board interviewed for the position included retired teacher Marie Moore and former school board member Dave Wise.
The board received a written letter from King at its June meeting announcing her resignation. She and her family had recently relocated to Vigo County after she accepted the presidential position at Saint Mary-of-the-Woods College.
King had served on the school board for seven years.
Meanwhile, the board also voted 6-0-1 in favor of making Northview High School Principal Tim Rayle the corporation's Assistant Superintendent.
Beasley abstained from the vote.
Board member Jennifer Kaelber motioned in favor of Rayle with Adams giving the second.
CCS Superintendent Kimberly Tucker told The Brazil Times the corporation will post the current principal position at Northview Friday and will begin the process of finding a replacement for Rayle as soon as possible.
"We're hopeful to have someone on board by the start of school," Tucker said.
The board meets regularly on the second Thursday of each month.
