POLITICIANS have created a “febrile climate” that has led to more parents keeping their children at home over disputes with schools, a headteachers’ union chief will say today.

The Association of School and College Leaders (ASCL) president John Camp will warn that the “unwritten social contract” between families and schools is “fracturing” as some politicians and commentators are “far too quick to take potshots at schools.”

In a speech at the union’s annual conference, he will call for a “change of tone” in the national conversation about education.
