Head teachers are increasingly worried about finding enough qualified teachers for the next academic year, as research suggests deputy heads are wary of becoming school leaders.
Job adverts for secondary school teachers are up 47 per cent on last year and 14 per cent on 2019, prior to the pandemic, according to SchoolDash, an education data company.
Surveys by Teacher Tapp, which polls school staff on their workplace, also found heads were worried about being unable to find enough suitably qualified teachers and technicians in time for the start of the next academic year.
