Incumbent Shirley Harris kept a wide lead over opponent Austin Dawkins and easily reclaimed her at-large seat.
Citing widespread poverty across the rural city, both candidates agreed not to spend money campaigning, or to compete with one another.
"I've done signs in the past, but this year Mr. Dawkins and I agreed to not run as opponents," said Harris, a 12-year school board member. "We are part of a small community, and we both are dedicated to serving our community. Either they know us or they don't."
Incumbents Mike Smith and Betty Johnson reclaimed seats two and four, respectively, without any opposition.
