Schools are struggling to recruit teachers, with tens of thousands of vacancies being advertised, according to new research.
The Recruitment and Employment Confederation (REC) said issues over pay were not being addressed.
Teachers are embroiled in a dispute over pay which has led to a series of strikes.
REC chief executive Neil Carberry said: “Schools are increasingly struggling to recruit this year with more than 46,500 job adverts.
“This is after the double-digit percentage rise in education vacancies we reported last month. This happens when employers fail to address pay and people’s experience at work.
“Teachers face a double whammy because their pay has stagnated, but they are also losing classroom help, such as teaching assistants and new technology, because of a squeeze on school budgets.”
