Promotion is dependent on your ability and potential to take up responsibilities at the next sub grade. Typically GEO 4 to GEO 5 takes longer. I know of colleagues who are still Geo 4 waiting to GEO 5 but already holding LH or SH positions for a few years.


Increment for GEO 4 to GEO 5 is about 400-450 , including and depending on merit increment, which is tied to your CEP and PB.

In lieu of your NPL and 3/4, I will think about 2 years after you get appointed as SH, unless your salary almost hits the ceiling scale, whichever is earlier.
