Getting Started Guide for Indian Forest Service

How to prepare for Indian Forest Service

Indian Forest Service is among the three All India Services – the other two being Indian Administrative Service and Indian Police Service.

An IFoS Officer, like his equivalents in the IAS and IPS occupies the top position in a district, with a rank equivalent to a DM who is an IAS, an SP, who is an IPS Officer.

The Union Public Service Commission is the common body responsible for conducting the entrance examination for both (a) the Civil Services for the IAS, IPS and other allied services   and (b) Indian Forest Service.

This is a comprehensive guide that has been prepared by ForumIAS that will help aspirants prepare for the Indian Forest Service Examination.
