The Indian Administrative Service (IAS) examination- A Brief Guide

The Indian Administrative Service (IAS) examination, conducted annually by the Union Public Service Commission (UPSC), is a formidable challenge and a dream for countless aspiring civil servants in India. As one of the most prestigious and competitive examinations in the country, the IAS examination opens doors to a career that transcends mere job prospects, offering an opportunity to contribute significantly to the nation’s governance and development.

The IAS examination is the gateway to India’s civil services and is often referred to as the “Mother of All Examinations.” It is conducted in three stages:

1. Preliminary Examination (Prelims)

The Preliminary Examination serves as the first hurdle. It consists of two objective-type papers – General Studies Paper-I and General Studies Paper-II (CSAT – Civil Services Aptitude Test). The Prelims is primarily a screening test to shortlist candidates for the Main Examination.

2. Main Examination (Mains)

Candidates who clear the Prelims proceed to the Main Examination. This stage involves a series of subjective papers, including Essay, General Studies-I, General Studies-II, General Studies-III, General Studies-IV, Optional Subject Paper-I, and Optional Subject Paper-II. The Main Examination evaluates candidates’ in-depth knowledge, analytical abilities, and writing skills.

3. Interview/Personality Test

The final stage is the Interview/Personality Test, where a board of experts assesses the candidates’ suitability for a career in the civil services. It evaluates their communication skills, depth of understanding, and overall personality.
