A question may be arises at the time of personality test about your higher degree and permission. If such may not be happen,then there is no question of service continuation.
But I can say, this permission from the D.I. is mandatory.
Before, when an in-service teacher would appear to sit for higher scale then there was a column for ” No objection” in application format filled by the H.M./SECRETARY. But now such column deleted.
So, if the question of permission would not be arise/a factor, then you will get service continuation.
Tanks a lot, TEACHERS’ DAY.
