⚡ TL;DR

The DAF (Detailed Application Form) is filled twice: DAF-I after clearing Prelims (to confirm Mains eligibility) and DAF-II after clearing Mains (to prepare for the Personality Test). Both have strict, non-extendable deadlines set by UPSC.

What Is the DAF?

The Detailed Application Form (DAF) is a structured form through which UPSC collects personal, academic, work-experience, hobby, and service-preference data about each candidate. It is the primary document used by the interview board to frame questions during the Personality Test.

Two Stages of DAF in the UPSC Calendar

FormTriggerTypical WindowPurpose
DAF-IAfter Prelims result~10 days (e.g., 16–25 June 2025)Confirms Mains eligibility; collects basic personal/academic data and initial service/cadre preferences
DAF-IIAfter Mains result~15 days (e.g., 13–27 Nov 2025)Detailed form that forms the basis of interview questions; verifies/updates information

Key Calendar Facts (CSE 2025 Cycle)

  • DAF-I window: 16 June 2025 to 25 June 2025 (6 PM)
  • A fee of Rs 200 applies (exempted for female, SC, ST, PwBD candidates)
  • DAF-II window: 13 November 2025 to 27 November 2025 (6 PM)
  • Interviews began January 2026 at Dholpur House, New Delhi
  • Missing either deadline disqualifies the candidate from the next stage

Why It Matters

Nearly 90% of interview questions originate from DAF-I and DAF-II entries. Every field — hobbies, work experience, educational background, positions held — is a potential question thread. Treat the DAF not as a form to fill but as a script for your interview.
