How I will get my pay as Vice-Principal

I sincerely hope that you will help me in my dilemma of a pay fixation with arrival of sixth pay Commission. My Basic on 01 January 2006 was 9000/- ( in the pay scale of 7500-250-12000) as I was working as a PGT in Navodaya Vidyalaya Samiti. In the same grade I received my senior scale in the year 2003 in which my pay was fixed from 6000-200-10500 to 7500-250-12000. In the year 2006 I received Promotion to the post of Vice-Principal in the same pay scale in which my pay was fixed by awarding two more increments, one lower and one higher to Rs. 9750 in the month of November 2006. (In the same year I also got my regular increment in the month of August 2006 in my previous scale) so the basic became from Rs. 9000 to Rs 9750. I still don't understand how to fix my pay in the sixth pay commission. You all are requested to guide me in this regard that how my pay can be fixed and what bunching benefits I can have.

I was PGT and Vice-Principal both in the same year, How fixation would be done ?

The Scale of Vice-Principal in Navodaya Vidyalaya Samiti is 7500-250-12000. I was already in this scale after completion of my Senior scale in the year 2003. Navodaya Vidyalaya Samiti has their own GR for fixing scale of a promoted person in the same scale by giving one upper and lower increment as per the provision of rule FR22(1)(a)(i) so my pay was fixed on the date of my promotion. So in the year 2006 I receipt 3 increments and my basic was changed from 9000 to 9750. Now I have a doubt that I was a PGT on January 2006 as well I was the promoted in the same year on the post of Vice-Principal in the same basic. So what would be my pay in the new sixth pay commission? Please guide me once again I am giving you my pay structures

Received Senior scale in the year 2003 from 6500-200-10000 to 7500-250-12000
1st January 2006 – PGT – Basic – 9000 (7500-250-12000)
August 2006 – PGT – Basic – 9250 (received the regular increment)
6th November Promoted as a Vice-Principal in the Same Basic by giving one
upper and one lower increment so the basic became 9750.
Thanks
