Baltimore County’s school board will not only have five new members on Tuesday but get new leadership as well. However, the options for experienced leadership are limited. Board members will elect a new chair and vice chair at the beginning of the meeting. Julie Henn and Rod McMillion, who both ran unopposed in the Nov. 8 election, currently hold those positions, respectively. And Henn, who has been the chair for the last year, said on Facebook that she no longer wants the job. In a Nov. 18 post, Henn said she told her colleagues that she’d neither pursue nor accept a nomination to be chair or vice chair.
