But TimePlan did not report Miss Gehring to the department. David Hart, general secretary of the National Association of Head Teachers, said today that the obligation to set in motion the DfES's procedures should not rest with the agency that employs a teacher under suspicion. "The agency has a commercial interest in a teacher remaining in employment," he said. He said police and social services, who work together in child protection teams, should be required to alert the DfES immediately any allegations are made. "That would give a second line of defence for schools," he said.
