The Civil Services Examination (CSE) is a national level competitive examination in India. It is conducted by the Union Public Service Commission annually, spanning over the better part of an entire year. It is conducted to recruit officers for the various Civil Services of the Government of India, including Indian Administrative Service (IAS), Indian Foreign Service (IFS), Indian Police Service (IPS), Indian Revenue Service (IRS) among others – better known as the ‘Indian bureaucracy.’

The examination is the toughest examination in India and one of the toughest in the World. The success rate (making it to the final list) is of the order of around 0.1%-0.3% of the applicant base. For IAS, IPS and IFS, the rate is about 1/4 of the the above figure. The number of applicants at the time of writing this article was around 1,000,000 with about half as many actually appearing for the prelims. Number of vacancies varies between 1000-1200 every year on average.

The exam is conducted in 3 stages, viz. the Preliminary (CSP), Main (CSM) and the Interview (Personality test) apart from a medical exam. The Indian Forest Service recruitment shares its preliminary stage with CSP.

The gross details such as eligibility, education, reservations, etc are notified every year at the time when the prelims form is released. Notifications are usually published on the UPSC website as a pdf, apart from being published in government employment magazines. The notifications can be downloaded form here : CSP / IFoS
