Since the controversial school reforms came into force last summer, every tenth teacher has resigned.
According to data collected between October 2013 and October 2014, it is mostly teachers who still have some time before retirement (in the 35-44 bracket), who have chosen to leave the public education system.
The number of resignations has increased by 30 percent – the equivalent of 1,236 teachers who no longer work in schools.
Hard time recruiting new teachers
Claus Hjortdal, the chairman of the Danish Association of School Leaders, believes there is always going to be fluctuations and is therefore not particularly worried about the numbers of teachers leaving.
He is, however, concerned about the recruitment of new teachers.
"It is really difficult to replace the former teachers, and it's a problem that cannot be solved by a quick fix," Hjortdal told Politiken.
"A lot has to change in order to motivate young people into teacher training again."
Foundations of elementary schools disappearing
Hjortdal argues that it may already be too late to solve some of the problems related to the low education level of many young teachers.
Similarly, Anders Bondo Christensen, the chairman of the Danish Teachers Union, worries about the negative development in the school system.
"Many municipalities already have difficulties in recruiting teachers. The entire foundation of elementary schools could disappear."
