The Delhi University Teachers' Association (DUTA) has written a letter to newly-appointed Human Resource Development (HRD) minister Prakash Javadekar on shortage of teachers in the varsity.
DUTA president Nandita Narain said that the number of students in the university had increased over the years while thousands of posts of teachers were lying vacant.
"Despite an increase in seats due to reservations for OBC students since 2007 and the promise of additional posts to universities, over 4,500 posts in DU remain vacant with teachers working on ad-hoc or guest basis," she said.
She also said that the high teacher-student ratio was affecting the quality of teaching and global ranking of the university.
"The (University Grants Commission has not released the second tranche of posts either, leading to extremely over-crowded classrooms and a very high student-teacher ratio that is not only affecting the quality of teaching but also the global rankings of our universities," said Narain.
"The denial of promotions to lakhs of teachers across the country since 2008 has already resulted in downgrading research and teaching in the universities, pushing the effective pay structure of university and college teachers way below that of All India Government Services, who have time bound promotions," she added.
