If you are participating in Staff Selection Commission (SSC) exams, you need to understand the newly introduced "Sliding Mechanism." The SSC introduced a Sliding Mechanism for the allocation of posts and departments to qualifying candidates.
This system was designed to address the problem of a large number of vacancies remaining unfilled each year because candidates were skipping Document Verification or failing to join their allotted departments. The core objective is to ensure the maximum filling of vacancies in a single exam cycle through a fair, merit-based process.
Here is a simple breakdown of how the single reallocation (sliding) round works for unused vacancies.
Step 1: First Round of Tentative Allocation (FRTA)
- Initially, candidate allocations are based on the preferences they submitted.
- To confirm this tentative allocation, candidates are required to visit their selected venue to complete Identity Verification (IV) via Aadhaar Authentication.
Step 2: The Big Choice – FIX vs. FLOAT
During the Identity Verification stage, candidates must make a crucial decision by choosing either the "FIX" or "FLOAT" option.
The "FIX" Option
- Choosing FIX means you accept your tentatively allotted post as final.
- You will not be considered for any further upgradation.
- If you choose FIX and then decide not to join, that vacancy simply moves to the next recruitment cycle.
- By choosing FIX, you must acknowledge that candidates lower in merit might get higher-preference posts in later rounds if they chose FLOAT.
The "FLOAT" Option
- Choosing FLOAT indicates your willingness to be upgraded to a higher preference post if vacancies arise.
- Important Warning: If you choose FLOAT and get upgraded, you must join the newly allotted post.
- If you fail to join the upgraded post, you will lose both your previously allotted post and the new upgraded post.
Step 3: Identity Verification (IV) Rules
- Candidates must log in to the Candidate Portal to book a slot (City/State, Date, and Shift) for Identity Verification.
- Once you book a slot, it is treated as final and cannot be changed.
- You must carry your Valid Aadhaar Card and the original printout of your slot selection confirmation slip to the venue.
- Once you book a slot, it is treated as final and cannot be changed.
- You must carry your Valid Aadhaar Card and the original printout of your slot selection confirmation slip to the venue.
- If you fail to appear during the verification window, you will be marked as 'Absent', excluded from any further process, and no representations will be accepted.
- If Aadhaar Authentication fails during the process, officials will check your biometrics or use facial recognition matched against photos taken during the examination; if all fail, your candidature may be cancelled.
Step 4: The Sliding Round & Final Result
- After the verification window closes, the SSC identifies all vacancies that opened up because candidates were absent for their Identity Verification.
- The SSC then conducts a single sliding round of allocation for the candidates who opted for "FLOAT," basing the upgrades on merit-cum-preference.
- Finally, an updated result with revised post allotments is issued, and e-dossiers are forwarded to the respective departments for final appointment.
- This final result is binding on all stakeholders.
Latest Sliding Mechanism Updates (April 2026)
Keep an eye on recent official changes to ensure you don't miss your verification window:
- Venue Selection Update: Candidates are no longer required to visit a default Regional Director (RD) office; instead, candidates must visit the venue selected as per his/her choice and indicated in the confirmation slip.
- Delhi Venue Extension: The slot booking window for the sliding process for the Delhi Venue is being extended by 01 (one) day i.e. 23.04.2026. Furthermore, for this venue - the candidates may book their slots up to 05:00 PM on 11.04.2026.
- Document Rules for Non-Aadhaar Candidates: Non-Aadhaar candidates must also bring their Aadhaar Card (in original). If authentication is mandatory for such candidates, they need to produce their Aadhaar Card (in Original) during Identity Verification (IV) at the chosen venue.
Step-by-Step Guide: How to Book Your Sliding Verification Slot
Accessing the Sliding Framework System is strictly for eligible candidates. Here is exactly how to navigate the portal:
Step 1: Access the Dashboard
- Log into the SSC candidate portal.
- If you are qualified, you will see a specific option on your dashboard: "Identity Verification / Sliding Venue Details". Non-qualified candidates will not see this option. Click "View" to proceed.
Step 2: Select Your Region & Venue
- You must select your preferred City/State, Date and Shift to report for Identity Verification.
- Crucial Warning: Ensure you pick carefully, as the Region once selected cannot be changed.
Step 3: Slot Booking (First-Come, First-Served)
- Slots are allocated strictly on a First-Come, First-Served basis.
- Each day contains four available time slots: 09:00 AM, 11:00 AM, 02:00 PM, and 04:00 PM.
- Green slots indicate availability, while Red slots mean the time is fully booked.
Step 4: Confirmation & Printing
- After confirming, the system displays your Candidate Information, Selected Date & Time Slot, and Verification Venue Details.
- You must bring the print out of this pass along with the Aadhar Card on the verification date.
What Actually Happens at the Verification Venue?
Do not take the Identity Verification process lightly. The SSC uses a strict multi-modal verification system to ensure authenticity.
- Three-Step Security Check: Verification includes Live Photo Capture at the Verification Venue, Aadhaar-based Biometric Authentication, and Fingerprint Matching with records available in the system.
- OTP Verification: The candidates are advised to bring the mobile which number is registered in application form for Aadhaar OTP.
- Signing the Declaration: During this process, you will be handed a formal "Declaration of Candidate" form. If you choose the "FIX" option, you will sign a document irrevocably accepting your current post and waiving any claim to higher preference posts, even if they open up in subsequent rounds. You will also be required to write a statement in your own handwriting acknowledging receipt of the declaration copy.
Frequently Asked Questions (FAQs) About the SSC Sliding Mechanism
Q: What is the difference between FIX and FLOAT options in the SSC sliding mechanism?
- A: The "FIX" option means you accept your tentatively allotted post as final and will not be considered for any further upgradation. The "FLOAT" option means you are willing to be considered for an upgradation to a higher preference post if vacancies arise.
Q: Can I keep my old post if I choose FLOAT but don't like the newly upgraded post?
- A: No. If you choose the FLOAT option and are upgraded to a higher preference post, you must join the newly allotted post. Failure to join the new post will result in the forfeiture of both your previously allotted post and the upgraded post.
Q: What happens if I miss my Identity Verification (IV) slot?
- A: Failure to appear within the provided window will result in you being marked as 'Absent'. Your candidature will be excluded from further processes, and no representations will be accepted regarding your absence.
Q: Can I change my slot or region after booking it on the portal?
- A: No. The slot once booked shall be treated as final, and no request for a change will be entertained. Additionally, the Region once selected cannot be changed.
Q: Are there multiple waiting lists or sliding rounds?
- A: No. The SSC will conduct only a single sliding round of allocation for candidates who opted for the FLOAT option. There is no waiting list or multiple rounds.
