One explanation can be increased administrative tasks, says Christina Sandström, a department head at the agency. "There have been additional tasks that maybe teachers don't think they should have to take care of," said Sandström, to Swedish Radio news.
The new administrative tasks include teachers having to assign grades to students at an earlier age and having to write assessment reports for each student.
The National Agency for Education's report finds that 64 percent of the teachers working during the school year 2006/2007 were still in the profession five years later. Twenty-four percent had changed professions completely and 12 percent had retired.
The report does not however show if teachers are leaving the profession more now compared to the past, nor how teachers' drop-out rates compare to other professions.
