Evolution of the Indian Administrative Service
Prior to India's independence, the service was known as the Imperial Civil Service (ICS) under British colonial rule. Following independence in 1947, Sardar Vallabhbhai Patel—widely revered as the Patron Saint of India's civil services—reformed the institution into the modern IAS, famously describing civil servants as the "Steel Frame of India" due to their non-partisan governance and administrative continuity.
How to Become an IAS Officer
Aspiring candidates must clear the three-stage Civil Services Examination administered annually by the Union Public Service Commission (UPSC):
- Preliminary Examination: Two objective multiple-choice papers (GS Paper 1 and CSAT Paper 2).
- Main Examination: Nine descriptive subjective papers assessing essay writing, general studies (I to IV), language, and an optional specialized subject.
- Personality Test (Interview): Comprehensive board interview evaluating intellectual caliber, moral integrity, leadership potential, and situational judgment.
Following final merit ranking and medical examination, selected probationers report to the Lal Bahadur Shastri National Academy of Administration (LBSNAA) in Mussoorie, Uttarakhand, for their foundational and professional administrative training.
