how many all india services are there in india
All India Services The All India Services (AIS) comprises Civil Services of India, namely the Indian Administrative Service (IAS), the Indian Forest Service (IFS) and the Indian Police Service (IPS) .[1] A common unique feature of the All India Services is that the members of these services are recruited by the Centre(Union government in federal polity), but their services are placed under various State cadres, and they have the liability to serve both under the State and under the Centre.[1] Due to the federal polity of the country, this is considered one of the tools that makes union government stronger than state governments. Officers of these three services comply to the All India Services Rules relating to pay, conduct, leave, various allowances etc.[2]
