Janice Johnson, the new superintendent of the Hattiesburg (Miss.) School District, submitted her resignation on her first official day on the job.

The Hattiesburg American reports that Johnson cited family and personal obligations as her reason for resigning.

Johnson will resume her position as assistant superintendent with the Biloxi (Miss.) district, a position she has held since 2012, The Biloxi Sun-Herald says.

In a statement released over the weekend by the Biloxi district, Johnson said: "After having had the opportunity to spend time in the [Hattiesburg] district over the last few days and understanding the demands that the position will place on me and my commitment to my family, I did not believe it would be in my family’s best interest for me to take the position. I have significant personal commitments that simply will not allow me to put the time and effort into the demands of the superintendent’s position. I wish the Hattiesburg School District all the best."

The Hattiesburg school board chose Johnson last month from a field of 31 applicants. She was hired to replace Superintendent James Bacchus, who resigned in December.

Hattiesburg School Board President Marcus Cathey said that Robert Williams, principal of N.R. Burger Middle School, will take over as interim superintendent.
