It has also mentions that in order to maintain parity between Field and Secretariat Offices, introduction of a level in the hierarchy of Central Secretariat having grade pay of Rs.4200 in the pay band PB-2 between the grades of UDC and Assistants is necessary. The manner in which the new grade in the hierarchy of Central Secretariat should be introduced may be decided by DOPT in consultation with Dept. of Expenditure.
