Critical Changes: The Read-Only Framework and Cadre Policy
Unlike previous cycles where candidates manually re-entered extensive academic and personal histories, the 2026 application process utilizes an integrated Common Application Form (CAF) framework. Most details are locked as read-only data carried over from your initial Prelims registration profile.
Candidates are primarily required to use this application window to complete a few vital updates:
- Cadre and Service Preference: This is the single most critical editable section. You must input your preference order for All India Services (IAS, IPS) and Central Civil Services (Group A) carefully. Mistakes made in these slots cannot be corrected later.
- DoPT Cadre Allocation Compliance: The preferences will be processed strictly under the latest Department of Personnel and Training (DoPT) zone-allocation guidelines. Failing to select a home state accurately or opting out of specific regional preferences will alter your ultimate service allocation matrix if selected.
- PwBD Accommodations: Eligible candidates with benchmark disabilities must use this window to formally declare requirements for assistive devices, updated large-font question papers, or verify scribe credentials.
UPSC Civil Services Main Exam Structure
The written assessment phase beginning on August 21 comprises nine conventional descriptive papers conducted across a multi-day testing schedule:
[Qualifying Papers: Indian Language & English] ➔ [Essay Paper] ➔ [General Studies I, II, III, IV] ➔ [Optional Subject Paper I & II]
- Qualifying Section (Non-Merit): Includes Paper A (Modern Indian Language) and Paper B (English), each carrying 300 marks. Candidates must score at least the baseline passing marks (25%) here to have their remaining main papers evaluated.
- Merit Section (1,750 Marks Total): Consists of 7 papers carrying 250 marks each—one Essay paper, four General Studies papers (GS I to GS IV), and two papers dedicated to your selected Optional Subject. Performance in this section determines shortlisting for the subsequent 275-mark Personality Test.
