NEWARK — Jennifer Holleran, a 20-year educator and former director of New Leaders for New Schools, has been chosen to lead Start Up: Education, the $100 million project funded by Facebook CEO Mark Zuckerberg in partnership with Newark Mayor Cory Booker and Gov. Chris Christie. Zuckerberg made the announcement about an hour ago during a news conference at Newark's Robert Treat Hotel. "The most important first step is working with Mayor Booker and the community," Holleran told The Star-Ledger today. "That's the most important thing — getting to know the community." Her appointment was among several details that emerged today regarding the announcement that Booker, Zuckerberg, and Christie would be leading a reform effort to turn around Newark's failing schools.
