UPSC Eligibility Criteria 2027 for General and Reserved Categories

There has always been a great deal of interest in the UPSC exam among students, as the exam is used to shortlist candidates for various All India Services and Central Government services. Success in this national-level competitive examination makes candidates eligible to proceed to the subsequent stages of the recruitment process for government jobs. If competitive salaries, generous retirement benefits, and long-term job security appeal to you, then you may consider appearing for the UPSC 2027 examination. However, checking the eligibility criteria beforehand is important. While most applicants focus on preparation and planning strategies to crack the exam, understanding the UPSC eligibility requirements in terms of educational qualifications, age limits, and the number of attempts is equally crucial.

To help you determine whether you are eligible to appear for the UPSC 2027 examination before investing your time and effort in preparation, we have compiled the minimum eligibility requirements for candidates belonging to both the General and reserved categories.

Educational Qualification Requirement for UPSC Exam

Students planning to appear for the Civil Services Examination conducted by the UPSC must note that a bachelor's degree from a recognised university is the minimum educational qualification required. There is no minimum percentage requirement for graduation. However, the degree must be awarded by a recognised university or an institution approved by the relevant authorities.
