The UPSC's approach to evaluating ethics and integrity has evolved over time, reflecting shifting societal values and expectations from public servants. Initially, the focus was primarily on knowledge-based assessments; however, the examination now incorporates components that test candidates' understanding of ethical dilemmas, moral reasoning, and values in decision-making contexts. Additionally, candidates are often presented with case studies where they must demonstrate ethical judgment. This evolution underscores the importance of cultivating a strong sense of public service ethics and responsibility in future civil servants.
