Deidra Bradley’s last day as principal of Medard H. Nelson Charter School was Oct. 17, network CEO Sametta Brown confirmed today.

The charter school will be run by its director of curriculum, Trinnell Spears, in the interim, Brown wrote in an email to The Lens, responding to questions. She is the leader of the New Beginnings Schools Foundation.

Brown did not specify why Bradley was no longer with the network and said the search for a new principal is underway.

The New Beginnings network oversees two elementary schools in addition to Nelson, and one high school.

Bradley was the only principal out of the four who didn’t resign in the  2012-13 school year. During that time the resignation of Capdau Charter School Principal J’Vann Martin went unannounced to parents for more than two weeks.

Following that, Lake Area High School’s replacement principal resigned during the first week of the 2013-14 school year, leaving the school after less than a year.

Bradley did not return a phone message left at her home.
