Headteachers say they are struggling to recruit professionals to teach core subjects likes English, maths and science.

This is according to a new survey by the Association of School and College Leaders (ASCL), which noted that 44 per cent of school leaders have vacancies in English posts, 52 per cent in maths and 50 per cent in science.

Further compounding this shortage of teachers is a fall in the number of youngsters going to university - principally because of high tuition fees - and a rise in the number of children entering secondary school.

Brian Lightman, general secretary of the ASCL, called on the next government to make sure “schools and colleges can recruit and retain the highest calibre of staff”.

“The existing teacher supply model does not work,” he continued. “Schools all over the country are experiencing unprecedented difficulties recruiting trainees, qualified teachers, middle and senior leaders.

“The next government must act urgently to ensure that effective processes are put in place to model numbers of teachers needed in each sector and region and then promote the status and value of teaching as a profession.”

The ASCL has developed a ten-point plan to help alleviate the “teacher supply crisis”, which it says both the government and the profession can work to deliver.

Some of the recommendations include reviewing and adapting the current teacher supply model, expanding the number of schools that are capable of delivering initial teacher training and launching a “profession-led” campaign to get more people into teaching.

“Teaching remains a great job which continues to offer people a rewarding and fulfilling career,” Mr Lightman went on to say.

“It is vital that the profession and government work together to emphasise this positive message. Teaching must be promoted as a high-status profession and a proposed Royal College of Teaching, to set standards and encourage professional learning, would help to do this.”
