1) Your teacher has to submit the EXPERIENCE CERTIFICATE from his school authority at the time of PERSONALITY TEST. ( It was written in the letter of personality test)
2) There is a number is allotted for the experience of years to prepare the merit list.
3) He/She has to submitted his/her approval letter from his D.I.
Is not it?
So, we can say, by these above supporting documents helps him/her to get his/her previous service continuation.
Thanks a lot.
