Slide vs Float in JoSAA 2027 — What's the Difference?
One upgrades within an institute, the other upgrades across your whole choice list.
Disclaimer: JoSAA 2027 has not begun and no official dates exist as of October 2026. The Slide and Float mechanisms themselves are stable, unchanging features of JoSAA counselling and are confidently explained below. Only specific 2027 dates are hedged — verify at josaa.nic.in once released.
Side-by-Side Comparison
| Aspect | Slide | Float |
|---|---|---|
| Scope of upgrade | Only within current institute | Across your entire ranked choice list |
| Can change institute? | No | Yes, if a better choice exists elsewhere |
| Can change branch? | Yes, within same institute | Yes, anywhere on your list |
| Risk of downgrade | None | None |
| Best for | Candidates committed to a specific institute | Candidates open to any better option on their list |
Example Scenario
Suppose a candidate is allotted Mechanical Engineering at NIT Trichy, but had ranked Computer Science at NIT Trichy, as well as Computer Science at a different NIT, higher on their choice list.
If they choose Slide: JoSAA will only check if NIT Trichy CSE becomes available for them — it will not consider the other NIT's CSE seat, even though it's ranked higher.
If they choose Float: JoSAA checks the entire ranked list — both NIT Trichy CSE and the other NIT's CSE are in play, and whichever is ranked higher and becomes available first is offered.
Quick Decision Guide
- Choose Float if you'd accept a better branch at a different institute too.
- Choose Slide if the institute itself is non-negotiable for you.
- Don't choose Slide expecting it to also check other institutes — it won't.
