There's a question that comes up a lot in Defence family WhatsApp groups around counselling time. It goes something like this:
"We registered under Defence category but the DEF quota seats are already full. Can we shift to General? Will the system consider us in the unreserved pool automatically?"
It's a fair question. And the answer is more layered than a simple yes or no. Let's go through it carefully - because getting this wrong can cost a seat.
First: Can You Change Category During AISSAC 2026?
Short answer - no.
No change of category is allowed at the AISSAC-2026 registration stage.
Whatever category you selected during the original NTA application for AISSEE 2026 is the category that follows your child through the entire admission process. There is no option on the AISSAC portal to switch from Defence (DEF) to General or to any other category during counselling registration.
This isn't a new rule. It has been consistent across multiple AISSAC cycles. No change in the category will be entertained after submission of the application form and no subsequent changes will be effective.
So if your child was registered as a Defence candidate and you're now regretting that choice, the formal category on record stays as DEF throughout the counselling rounds.
But Wait - There's a Way the System Handles This
Here's where it gets more interesting for Defence families.
The AISSEE reservation framework doesn't mean a DEF candidate is completely locked out of General seats. The system has a built-in redistribution process that, in some cases, automatically moves a strong-ranking Defence candidate into the General (unreserved) pool.
25% of seats are reserved for wards of Defence personnel and ex-servicemen out of the balance seats after SC, ST, and OBC-NCL reservations.But if a DEF candidate's rank is strong enough to qualify in the General merit list - not just the DEF quota - they can be considered for a General category seat. The merit determines this, not a manual request.
Think of it this way. If your child scores in the top percentile and General seats are still open at the time of allotment, the system may place them in the General pool even if they registered as DEF. The DEF tag gives them access to the 25% DEF reservation - but it doesn't prevent them from competing in open merit if their rank is competitive enough.
What Happens When DEF Seats Go Unfilled?
This is the real question that most Defence families should be thinking about - and very few do.
Sainik Schools with deficiency in any category or categories shall notify on all the schools' websites with details of category-wise unfilled vacancies and marks of the last candidate admitted in each category, inviting applications from candidates in the Waiting List of other Sainik Schools.
So if DEF seats at a particular school remain vacant after allotment rounds - because not enough DEF-category candidates with competitive ranks applied or qualified - those seats don't simply disappear. They get redistributed. Reallocation of unfilled reserved seats may happen to other categories or quotas as per prescribed rules.
This means a General category candidate on the waiting list may ultimately receive a seat that was originally designated as a DEF seat. And in some cases, a DEF candidate with a slightly weaker rank may benefit from the same redistribution if other DEF candidates chose to Exit or failed their medicals.
The redistribution happens school by school, category by category, after each round of counselling. It's not announced with much fanfare, but it's happening in the background throughout the process.
The Coast Guard and Assam Rifles Situation
There's a specific and important note that many families miss entirely.
Wards of Coast Guard and Assam Rifles personnel are advised not to select Defence Category, but are required to select SC, ST, OBC-NCL, or General category option as applicable. They will be considered for Defence Category only if there are vacancies after the admission of wards of serving and ex-service defence personnel. Wards of Coast Guard and Assam Rifles personnel are not entitled for Defence scholarship.
This catches people off guard every year. If your child's parent serves in the Coast Guard or Assam Rifles and you registered under DEF category expecting full Defence benefits - that may not be how the system treats it. They get a shot at DEF seats only after regular Defence candidates are accommodated.
If your family falls in this bracket and registered under DEF, your child's effective category in the merit list behaves differently from a child whose parent is in the Army, Navy, Air Force, or ex-servicemen pool. Understanding this distinction before counselling matters.
What DEF Category Actually Gives You
It helps to be clear-eyed about what the Defence tag does and doesn't do.
What it does: It places your child in the DEF merit list alongside other Defence candidate children. Defence Personnel and Ex-Servicemen Category candidates must be considered under General Category - they must meet the same aggregate requirement as General Category.So the qualifying score bar is the same as General - your child still needs to meet the minimum percentage requirements, not the lower SC/ST bar.
Within the DEF pool, your child competes only against other DEF candidates for those 25% of seats. If the DEF pool is smaller or less competitive at a particular school - and it often is - your child's chances there may actually be better than in the General pool at the same school.
What it doesn't do: It doesn't lower the qualifying bar. It doesn't allow you to switch to General later if DEF seats are scarce. And it doesn't guarantee fee concessions automatically - those have separate eligibility criteria that must be verified at the school.
The Practical Reality for DEF Candidates During Counselling
Here's what this all means in real terms when you're sitting with the AISSAC portal and filling 10 school choices.
Your child will be allotted seats from the DEF quota at each school. If no DEF seats are available, the system checks whether your child qualifies in General merit. If yes - and if General seats are still open - they may be slotted there. If no - they move to the next school on your preference list.
Category of students - Gen, OBC-NCL, SC, ST, DEF - is one of the key factors considered during seat allotment.It works alongside rank, gender, and domicile. All four factors determine whether your child gets a seat at any given school.
The practical advice for DEF candidates: don't fill your choice list assuming DEF seats will be available at every preferred school. Check the seat matrix carefully on the AISSAC portal before locking. Some schools have very few DEF seats in a given year. At those schools, your child's chances depend entirely on whether their rank clears the General bar. If it doesn't, they need the next school on the list to have DEF vacancies.
Filling all 10 choices remains just as important for DEF candidates as for everyone else - perhaps more so, because the DEF seat pool is smaller and more variable across schools.
What About the Defence Scholarship?
This is separate from category-based seat allotment, but it's worth clarifying.
Wards of serving and ex-service Defence personnel who qualify through the DEF quota are eligible for fee concessions through the Defence Scholarship scheme. However - and this matters - Wards of Coast Guard and Assam Rifles personnel are not entitled for Defence scholarship,even if they are considered under the DEF quota for seats.
At the time of physical verification at school, you'll need to produce the service certificate or PPO (for ex-servicemen) to claim the scholarship. A general parent being placed in the DEF quota by any means does not automatically qualify them for Defence scholarship benefits.
The Bottom Line for DEF Families in AISSAC 2026
You cannot change your category during counselling - that's fixed. But the system isn't rigid about where DEF candidates end up. A strong rank can carry your child into the General pool automatically. Unfilled DEF seats get redistributed. And within the DEF pool itself, competition is often lower than in General - which is an advantage if your child's rank sits comfortably there.
What matters most: know your child's rank clearly, check DEF-specific seats at each school on the seat matrix, and fill your choice list with realistic options across all 10 slots. Don't rely on DEF quota alone when General seats may also be within reach.
