The UPSC encourages the use of regional languages in examinations to promote inclusivity and make the process accessible to a larger segment of the population. Students can opt for regional languages in their answer sheets for various papers. This policy aims to acknowledge the linguistic diversity of the country and helps candidates express themselves better in their preferred language, thereby ensuring a fairer evaluation of their knowledge and understanding. It also reflects the commitment of the UPSC to uphold the principles of equality and social justice.
