Students and teachers in the Ambridge Area School District return to class today, according to Beaver County Radio News Correspondent Sandy Giordano. No new talks have been scheduled  between the teachers union and the board to award a new contract.  Ira Weiss, district solicitor said yesterday that the state mediator hasn’t been in contact with the district to schedule any negotiations. The teachers contract expired on June 30, 2015.  Wages and health care costs are the sticking points, according to Chris Konkus , spokesperson for the teachers union .
