There has been a sharp drop in the percentage of All India Services officers — Indian Administrative Service (IAS), Indian Police Service (IPS) and Indian Forest Service (IFoS) — taking a posting in the central government at senior management grades. It has been matched with an explosion in the number of officers of the same cadres posted to the states.
Consequently, more than half of the senior management grade officers at the Centre are now from services other than these three All India Services. As the table shows, the pace of change in just a few years has been striking.
