Commenting on new data from the OECD , Daniel Kebede, general secretary of the National Education Union, said:
"This new data from the OECD confirms that we are facing a teacher retention crisis, with England having among the worst attrition rates among developed nations. Almost 10 per cent of English teachers left the profession in the most recent year of analysis, over three times the rates recorded in France and Ireland. Only three countries in the sample recorded worse teacher leaver rates [Lithuania, Denmark and Estonia].
"While attrition in other countries tended to be split evenly between retirees and teachers quitting for other reasons, over 90% of teachers leaving in the UK were voting with their feet and leaving before retirement, the highest rate in the sample.
"Without significant government action to reduce workload, improve school funding and teacher pay we will continue to lose teachers at an unacceptable rate, while being unable to recruit new ones to fill the gaps".
