Candidates who successfully clear the UPSC exams are awarded various rankings based on their performance. These rankings determine their placement in different services like the Indian Administrative Service (IAS), Indian Police Service (IPS), and other central and state services. The final ranking is crucial because it influences cadre allocation and the specific roles assigned to successful candidates. The top-ranking candidates get preferred services, while lower-ranked candidates are assigned to less popular options. This ranking system ensures that the most competent individuals are positioned in key governmental roles.
