The Prince George’s County school system has hired a new director to head the district’s transportation system, which fielded numerous complaints last year about late and crowded school buses.

Lori Carter-Evans, who ran the Henrico County school district’s transportation system for two years, replaces Thomas Bishop, who resigned earlier this year. Bishop was hired in 2012.

“My goals for Prince George’s County are to increase on-time bus performance and build strong partnerships with our stakeholders,” Carter-Evans said in a statement. “I hope to expand partnership opportunities with parents, regularly visit bus lots and stops and build a strong transportation team.”

The school system has also hired Sarah Woodhead, who has worked in Arlington and the District as director of design and construction and chief of facilities, respectively, as its new director of capital improvement programs. She comes to Prince George’s from CDM Smith, an engineering, construction and operations firm.

“We are thrilled to have both of these staff members to join our team,” said Alvin L. Crawley, the interim superintendent of schools. “We have faced some challenges in these areas over the past few years, and both of these directors bring a wealth of knowledge and expertise to the position.”

The hires were made before the new state law, which revamped the governance structure of the school system, took effect last month. They were made public last week.

Board Chairman Segun Eubanks said the elected board needed to fill the director positions so the school system can be ready for when school reopens in August.

“We kept saying we have to keep the system going,” he said. “I would have had concerns if they filled executive cabinet positions” before Kevin Maxwell, the new chief executive officer started.
