Salem, Kancheepuram and Tiruvannamalai are some of the other districts in Tamil Nadu with a large number of sanctioned teacher posts lying vacant, according to the Rashtriya Madhyamik Shiksha Abhiyan (RMSA) Survey for 2012-13. In districts like Chennai, there are more teachers available than the sanctioned posts.
Another indicator of the huge scarcity of teachers is the high pupil teacher ratio (PTR), ie number of students per teachers. There are 387 schools in Tamil Nadu with a PTR of 100 or more.
Vellore district has the highest number of such schools- 55.
Kancheepuram-49, Krishnagiri-36, Cuddalore -27, Chennai and Dharmapuri-25 are other districts with many schools falling under the category.
Over 4.5 lakh students in the State study with PTR equal to or more than 100, leaving teachers overburdened.
