240 - 250+ |
| OBC | Slightly lower than General | 235 - 250 |

Cut-off varies each year depending on the difficulty level, number of candidates, and vacancies.
Candidates qualifying the Preliminary Examination will be eligible to appear for the IES Mains Examination 2026, which consists of conventional (descriptive) papers. Aspirants are advised to begin mains-oriented preparation immediately without waiting for the prelims result.
