The evaluation of answer scripts in the UPSC exams ensures subjective fairness through a structured marking system. Evaluators are trained to adhere to specific evaluation criteria, focusing on content relevance, clarity, coherence, and depth of analysis. Use of multiple evaluators for the same script helps mitigate bias, as discrepancies can be discussed and resolved collaboratively. Detailed marking guidelines provide consistency across assessments. Furthermore, thorough feedback mechanisms allow for addressing issues raised by candidates, enhancing transparency in evaluation. These measures collectively foster a fair and just assessment process.
