What the IISER Round 4 Allotment Letter Shows
The allotment letter/offer displayed on the dashboard typically includes the candidate's name, application number, IAT rank, category, the IISER campus and programme allotted, and the deadline to respond. Candidates should verify all details carefully and report any discrepancy through the official grievance channel on the portal.
What Happens After Round 4?
Candidates who float their seat or remain unallotted after Round 4 will be considered in Round 5, scheduled for August 24 to August 26, 2026. Seat movement across rounds typically occurs as higher-ranked candidates float and upgrade to more preferred campuses, opening vacancies for candidates further down the merit list. Candidates who wish to exit the counselling process entirely can do so through the withdrawal option on the portal, subject to the applicable refund policy of the institute.
