The business climate for dealmaking in the K-12 marketplace should be a favorable one in 2015, according to Mary Jo Zandy, a managing director at Berkery Noyes, a New York-based investment bank. “I think it will be a good year for M&A activity in education in general,” said Zandy, whose firm recently released its 2014 Education Report, tracking sales and purchases of education companies that serve students and professionals from 2012 to 2014.
