Prince George’s County Schools Chief Kevin M. Maxwell has hired a former school superintendent from Delaware to serve as deputy superintendent, signaling that Maxwell has not finished assembling his new executive cabinet.

Shawn Joseph, who served as the superintendent for the Seaford School District for two years, is making a return to the Washington region.

Before taking his position in Delaware, Joseph served as the director of school performance for the Montgomery County School System. He earned a doctorate degree in education from George Washington University and has served as an adjunct professor at the school.

Max Pugh, a spokesman for the Prince George’s County School System, said Joseph is expected to begin in Prince George’s on March 10.

In a letter on the Seaford School District Web site announcing his resignation, Joseph said he was leaving Delaware because of family reasons.

“As you know, my family has not been able to relocate with me to the Seaford community, and I have resided in Seaford and Gaithersburg over the past two years,” he wrote. “Professionally, I could not be happier as we have worked collectively to inspire our children to achieve higher levels of academic performance. Graduation rates have increased and all of our schools have data which suggests students are learning at higher levels.”

Joseph will fill a new role in the administration, joining Deputy Superintendent Monique Davis in the No. 2 spot.

His responsibilities will largely be the same as those of former chief academic officer A. Duane Arbogast, who resigned this month. Arbogast, who had served as the chief academic officer for years, was named acting deputy superintendent of academics before William R. Hite, the former superintendent, resigned. Arbogast served in that capacity under Alvin Crawley, the district’s interim superintendent, but was reassigned to his previous position shortly after Maxwell took over.

Joseph interviewed for the Prince George’s school superintendent’s job more than a year ago when the Board of Education was looking for a permanent superintendent. Joseph was not one of the three finalists chosen by the board, and that search process was halted when County Executive Rushern L. Baker III (D) sought a takeover of the system.
