The State Police Services (Devanāgarī: राज्य पुलिस सेवा, Rājya Polīce Sevā), simply known as State Police or SPS are police services under the control of respective state governments of the States and territories of India.
The recruitment to this service is done by the respective State Governments, usually through State Public Service Commissions. The recruitment to SPS is also on the same pattern as that for IPS. The only difference is that the recruitment of SPS officers is made by the State Public Service Commission concerned through usually a combined competitive examination for State Civil Services which in the case of IPS is through the All-India Civil Services Examination conducted by Union Public Service Commission . However, in case of Union Territory, recruitment to SPS is also made by Union Public Service Commission through the Civil Services Examination as one of the Group-B Services. State police requirement in large States like Tamil Nadu, Uttar Pradesh, Madhya Pradesh, Bihar, Rajasthan, Maharashtra and Andhra Pradesh is greater as compared to the smaller States like Himachal Pradesh, Punjab, Haryana, Kerala, Sikkim and north-eastern States. After selection, which again is based upon the choice of service and merit of a candidate, selected candidates are required to undergo vigorous probationary training before getting posted as ACP or DSP.
Gazetted officers include all the Indian Police Service officers and all State Police Services officers of and above the rank of Deputy Superintendent of Police (DSP) or Assistant Commissioner of Police (ACP) in State Police and Metropolitan Police forces respectively.
