The Uncovenanted category of civil services was for the entry of Indians on the lower side of administration. 

The Special Civil Service comprised a specialised nature of services like forest service, Imperial Police and Political Service. After 1893 an annual exam was conducted to recruit the officers in Imperial Police service. However in 1858 the Indian Civil Service (ICS) or say Imperial Civil Services came into being that replaced the HEICCS of East India Company. The Government of India Act 1919 split Indian Civil Service into two categories – All India Services and Central Services. The last appointment to the ICS posts was in 1942. The Central Cabinet constituted Indian Administrative Service (IAS) in 1946.

IAS is a Part of All India Services
