Last verified: 11 October 2026 (Sunday evening). The validity rules below are CONFIRMED general norms from national-level exam guidance (two independent education sources). The AISSEE 2027 bulletin is not out yet — the date recommendation for this cycle is EXPECTED, based on the same rule applied to 2026 exams. This is a milestone-tied explainer, not breaking news: the form is expected in October 2026, so category paperwork must be ready tonight.
Of all the documents that sink a Sainik School admission, category certificates are the quietest killers. Nobody panics about them in October — and then, at counselling in spring, a certificate issued two years ago gets rejected and the seat goes to someone else. If your child is applying under OBC-NCL or EWS for AISSEE 2027, tonight is the night to check the date on that certificate.
Here is what exam authorities actually do:
Apply the same logic to AISSEE 2027: hold a certificate issued on or after 1 April 2026 (EXPECTED — the 2027 bulletin will confirm, but every national exam follows this pattern). If your certificate predates that, get a fresh one issued now, while tehsil offices are still operating at normal speed.
Two related facts worth knowing: SC/ST certificates usually carry lifetime validity — no renewal worry there. PwD certificates are often valid for around five years, but check yours against the disability percentage and reissue rules.
AISSEE is a national examination. For it you need a Central OBC-NCL certificate — one that cites the Government of India’s Gazette resolution recognising your caste in the Central OBC list. A state OBC certificate is valid only within that state, for state-level admissions and jobs. Showing up at AISSAC counselling with a state-only certificate under a central quota is one of the most common — and most avoidable — document rejections in the country.
The AISSEE 2027 notification is expected in October 2026 — last year’s dropped on 10 October. Tehsil and SDM offices slow down as festival season deepens (Diwali is 8 November), and a fresh OBC-NCL certificate typically takes 10–30 days from application to issue. If you apply this week, the new certificate lands comfortably before the form’s closing date. Wait until the form is live, and you will be queuing behind everyone else.
One caution from real counselling floors: some portals and offices resist issuing a fresh certificate if the old one “looks valid” — national exam authorities have still rejected such certificates when they predated the financial-year cutoff. For AISSEE, follow the exam’s rule, not the clerk’s.
How long is an OBC-NCL certificate valid for AISSEE 2027? Treat it as valid for one year. Exam authorities commonly ask for a certificate issued within the last year, and for counselling it is safest to hold one issued on or after 1 April 2026, covering the current financial year.
How long is an EWS certificate valid? EWS certificates are typically valid for one financial year. Like OBC-NCL, the safe move is a fresh certificate issued on or after 1 April 2026 for the AISSEE 2027 cycle.
Who issues the OBC-NCL and EWS certificates? OBC-NCL certificates are issued by the SDM or District Magistrate; EWS income and asset certificates by the Tehsildar or SDM. They must carry the official seal, the issuing authority’s signature and a clear date of issue.
Is a state OBC certificate enough for AISSEE? AISSEE is a national-level exam, so get a Central OBC-NCL certificate citing the Government of India’s central OBC list. A state OBC certificate is valid only for state-level admissions and jobs.
