UPSC CSE Prelims 2026 Overview

UPSC CSE Prelims 2026 Guidelines: The Union Public Service Commission (UPSC) is set to conduct the Civil Services Preliminary Examination on Sunday, May 24, 2026. A large number of candidates are anticipated to participate in this nationwide examination. In light of this, the Commission has released stringent guidelines that candidates must adhere to, focusing on aspects such as timing, dress code, required documents, and prohibited items. Non-compliance with these regulations may lead to disciplinary measures against the candidates.

Entry Timings and Examination Schedule

**Gates to Close at 9:00 AM and 2:00 PM**
UPSC has made it clear that entry will be restricted 30 minutes before the exam starts. Therefore, candidates will not be allowed entry after 9:00 AM for the morning session or after 2:00 PM for the afternoon session. The first shift will commence at 9:30 AM, while the second will start at 2:30 PM. Candidates are strongly advised to arrive at the examination venue well ahead of time.

Examination Conduct Rules

During the exam, candidates must use only black ballpoint pens for filling out both the OMR and attendance sheets. Any answers marked with pens of different colors will not be considered.

**Mobile Phones and Smartwatches Strictly Prohibited**
UPSC has enforced a total ban on mobile phones, Bluetooth devices, smartwatches, cameras, pen drives, and other electronic devices within the examination center. Only standard wristwatches are permitted, while digital watches with communication features are not allowed.

Mandatory Documents for Candidates

**Admit Card and Photo ID: Mandatory Requirements**
It is essential for candidates to bring their Admit Card and a valid photo ID to the examination center. The ID must match the number indicated on the Admit Card. Additionally, candidates should keep their e-Admit Cards safe until the final results are announced. **Extra Photographs Required for Some Candidates**
Those whose photographs on the admit cards are unclear or lack their name and date must bring two extra passport-sized photos along with a declaration to the exam center.

Permitted Items at the Examination Center

**Only Essential Items Permitted at the Examination Center**
Candidates are allowed to carry only necessary items such as a printed admit card, a pen, a pencil, a photo ID, and required photocopies. Bags, valuables, and other personal items are prohibited. The Commission has stated that it will not be responsible for any personal belongings lost during the examination.

Answer Key and Objection Process

**Answer Key to be Released Earlier This Time**
This year, the UPSC plans to publish the Provisional Answer Key right after the Preliminary Examination. Candidates will have the opportunity to submit objections through the online portal until 6:00 PM on May 31, 2026. Previously, the answer key was released only after the final results, but this change allows candidates to evaluate their performance sooner.

**Evidence Required to Lodge Objections**
To contest a specific question or answer, candidates must provide evidence from three credible sources. The Commission will review all objections with a team of subject matter experts before finalizing the Answer Key.

New Technology for Verification

**Verification via AI-Based Face Authentication**
This year, UPSC is implementing AI-based face authentication at all examination centers to combat impersonation and cheating. This new system is designed to be quicker and more secure than traditional verification methods.

Vacancies for UPSC CSE 2026

**How Many Vacancies Are There This Year?**
For the 2026 Civil Services Examination, UPSC will fill a total of 933 positions. Additionally, 40 posts are designated for the Indian Forest Service Examination.
