7 Out Of 10 ASTI Principals Say They Don't Think Social Distancing Can Work In Their Schools' Corridors 

The ASTI says it's one of the "serious infrastructural challenges" laid bare by a poll of 50 principals trying to implement the Department of Education's pandemic guidelines. 

84% say their school has no ventilation system, and a quarter no hot water in bathrooms. 

ASTI general secretary Ann Piggott says many schools were too crowded for comfort long before Covid-19.
