It ensures merit-based recruitment and aims to select the most qualified individuals for responsibilities that govern the nation's diverse administrative machinery. The UPSC plays a critical role in maintaining the standards and integrity of civil services by establishing examination patterns, setting syllabi, and evaluating candidates through rigorous assessments, ultimately helping to uphold public service commitment and accountability.
