Messages left with board members at the charter schools were not returned Tuesday. David Stiles, the vice president of operations and development for the schools' management company, Newpoint Education Partners, said he was tied up in meetings and did not answer specific questions sent in an email. Newpoint provides services to several schools in Florida and Ohio, according to its website. One of those schools — Newpoint High of Tampa — closed after four years of operation in 2013 because of governance and financial issues, district records show.
