Introduction & Significance

Public Administration (PA) is the practical science of managing public affairs and implementing government policy. Among Paper III topics, Topic 112 carries the highest PYQ track record — it has yielded marks in every exam from 2013 to 2023 (41 marks total; 8.2 avg/year). In 2026, the examiner is likely to test NPM, Good Governance, or NPS — areas that were lighter in 2021–23 PYQs.

PA exists because modern government cannot survive without an administrative apparatus. Even in ancient India, Kautilya's Arthashastra (~300 BCE) outlined a detailed administrative hierarchy. The British Raj gave India the Indian Civil Service (ICS) tradition — a system of generalist administrators that continues in the form of IAS and RAS.

Why study PA? The RAS officer is literally the product of the administrative system this chapter describes. Understanding PA's evolution from Weber's bureaucracy to NPM's efficiency drive to NPS's citizen service is essential for both exam performance and professional practice.
