„TALIS 2013 results show that, across all participating systems, teachers who teach a larger number of students with special needs are employed in less supportive and collaborative, as well as low-resourced, school environments. Students in high-need classrooms are more likely to be taught by less-experienced teachers and by those who have received less training than teachers in other classrooms.“
