The Union Public Service Commission (UPSC) declared the result of the Civil Services Preliminary Examination 2025 on June 11, 2025, for the exam held on May 25, 2025.

With the announcement of roll numbers of candidates qualified for the CSE Mains Exam, UPSC has also issued key instructions for the next step - uploading documents through the Detailed Application Form (DAF-I).
Candidates who have successfully cleared the Prelims are now eligible to appear in the Civil Services Mains Examination 2025, tentatively scheduled for September 2025. Before that, they must complete the DAF-I process, which includes the submission of essential documents in the prescribed format.
The Detailed Application Form-I (DAF-I) is an important stage after the Prelims result, where qualified candidates provide detailed personal, academic, and optional subject information. It is also the stage where document uploads are mandatory to verify eligibility.
As per UPSC guidelines, the following documents must be uploaded in scanned PDF format:
Each document should be legible and within the size limits specified by the UPSC (usually under 300KB per file in PDF format).
| Activity | Tentative Date Range |
| DAF-I Portal Opens | Mid-June, 2025 |
| Last Date to Submit DAF | Last June or Early July |
| Mains Admit Card Release | August, 2025 |
| CSE Mains Exam | September 2025 |
Once the DAF-I is submitted and verified, UPSC will release the Mains admit cards and exam schedule. Mains-qualified candidates will then appear for nine descriptive papers, including the essay, four GS papers, two optional papers, and two language papers.
Candidates who successfully complete the Mains will be shortlisted for the personality test (interview) stage in 2026.

Clearing the UPSC Prelims 2025 is a significant achievement, but it is only the beginning. Uploading the correct documents as part of the DAF-I submission is a critical step in ensuring eligibility for the Mains exam. Candidates must follow the UPSC's instructions meticulously to avoid disqualification at this stage.
