http://www.bbc.co.uk/news/education-35531982 Teacher shortages in England are growing and the government has missed recruitment targets for four years, the official spending watchdog has said. It means 28% of secondary physics lessons are taught by teachers with no more than an A-level in the subject, the National Audit Office report says. Ministers have a "weak understanding" of local teacher shortages, it adds. The government said overall teacher numbers had risen and blamed unions for "talking down" the profession. While the overall number of teachers has kept pace with rising pupil numbers, teacher shortages are growing, particularly in poorer areas and at secondary level, according to the authors.
