Thousands of new teachers never make it to the classroom, according to a new report
Many fail to finish training courses, while others struggle to find jobs, according to the Good Teacher Training Guide 2012.
Researchers at Buckingham University analysed official data on teacher training for the 2010/11 academic year, looking at where trainees study, the numbers entering the profession and the types of qualifications they hold.
The findings show that in 2010/11, 70.4% of 37,734 teacher trainees were in teaching posts the following January, meaning around 11,000 did not enter the profession.
Report author Professor Alan Smithers said: "Some people start with teacher training and it becomes clear to them that they are not going to make good teachers, and others successfully complete and they're not necessarily able to find a job,"
Ministers have announced plans to overhaul teacher training, moving it away from universities into schools.
