The UPSC ensures fairness and objectivity in its examinations through a structured assessment process that includes multiple stages: the preliminary, mains, and interview. The exam is designed to test candidates on various dimensions, from knowledge to aptitude. The evaluation is done through anonymous marking to minimize biases, and the syllabus is revised periodically to keep it relevant. Furthermore, the selection of examiners and a well-defined evaluation criterion contribute to maintaining a high standard of fairness in the examination process.
