🔄 Last verified: 26 September 2026 — ⚠️ NTA has not released the 2027 bulletin yet. The age cutoffs below are 🔶 PROJECTIONS — derived by shifting the AISSEE 2026 bulletin (via TOI, citing NTA) one year forward. Final confirmation comes with the bulletin (expected October 2026).
The age rule is AISSEE’s strictest. Low marks? You can always try again next year. But miss the age cutoff by a single day, and the form is rejected outright — no appeal, no second chance. So read this carefully, and match it against your child’s birth date.
At a school in Ranchi, a father’s face fell when the teacher said, “Your son misses the cutoff by nine days.” Nine days — after a full year of preparation. This guide exists so no parent learns it that way.
| Class | Age as on 31 March 2027 | Birth date (🔶 projected) |
|---|---|---|
| Class 6 | 10–12 years | 1 April 2015 – 31 March 2017 |
| Class 9 | 13–15 years | 1 April 2012 – 31 March 2014 |
Why these dates: the 2026 bulletin set Class 6 at 1 Apr 2014 – 31 Mar 2016 and Class 9 at 1 Apr 2011 – 31 Mar 2013 (TOI, citing the NTA bulletin). The window shifts forward by one year every cycle — hence the projection above.
Find your child’s birth date below. Honestly, this table answers 90% of parents’ questions:
| Date of birth | Age on 31 March 2027 | Eligible? |
|---|---|---|
| 30 March 2015 | 12 years, 1 day | ❌ No — over-age by a day |
| 1 April 2015 | 11 years, 11 months | ✅ Yes |
| 15 June 2015 | 11 years, 9 months | ✅ Yes |
| 31 March 2017 | Exactly 10 years | ✅ Yes — the range is inclusive |
| 1 April 2017 | 9 years, 11 months | ❌ No — under-age by a day |
See how brutal those edges are? One day. That’s why you calculate — never estimate.
The golden rule: age is counted as on 31 March 2027 — not today’s date, and not the exam date (31 January 2027) either. This single misunderstanding disqualifies more applications than you’d believe.
Example 1 — eligible ✅ Born 15 June 2015. On 31 March 2027, the child is 11 years and 9 months old — inside the 10–12 band → eligible for Class 6 (projected).
Example 2 — not eligible ❌ Born 2 April 2017. On 31 March 2027, the child is 9 years, 11 months and 29 days — two days short of 10 → not eligible. Painful, but the rule is the rule.
Example 3 — Class 9, eligible ✅ Born 10 October 2012. On 31 March 2027, the child is 14 years and 5 months — inside the 13–15 band → eligible for Class 9 (projected).
No — the age criteria are identical for girls. The difference is only in seats: in the 33 established schools, 10% of Class 6 vacancies or 10 seats, whichever is more, are reserved for girls ✅ (per the AISSAC SOP). Not 25% — if you’ve seen that figure somewhere, it’s wrong. The girls’ admission guide covers everything else.
Straight answer: SC/ST candidates get relaxation in qualifying marks (the 25%-per-section + 40%-aggregate rule doesn’t apply to them ✅) — but there is generally no relaxation in age. This has held steady for years. The bulletin, of course, has the final word.
Keep these ready for the application form and for counselling:
⚠️ The date of birth must match across all three documents. If the birth certificate and the school record disagree, get it corrected now — after the form is submitted, corrections are practically impossible.
Q1. My child turns exactly 10 on 31 March 2027 — eligible? Yes. The 10–12 range is inclusive, so a 31 March 2017 birth date qualifies (projected).
Q2. Can the date of birth be corrected after submitting the form? NTA usually opens a limited correction window (the 2026 cycle had one), but DOB is a critical field and corrections there are difficult. Get it right the first time.
Q3. Must a Class 9 applicant have passed Class 8? Yes — from a recognised school ✅ (per the 2026 bulletin).
Q4. Do children of defence personnel get age relaxation? No. The defence quota sits in seats (25% of the remainder ✅), not in age.
Q5. Could the bulletin change the age rule? The pattern has been stable for years — a change is 🔶 unlikely. But the final word is always the bulletin’s (expected October 2026).
Q6. Which date actually matters — the exam date or 31 March? 31 March 2027. Always 31 March. Not the exam date, not today’s date.
