Headteachers are being forced to cancel school trips, scrap swimming lessons and slim down timetables amid a “looming funding crisis” in the education sector, unions have warned.
Geoff Barton, general secretary of the Association of School and College Leaders (ASCL), said institutions across the country were “clawing back money wherever they can” as soaring inflation eats into allocated funding.
