India School Admission Age Calculator (CBSE, ICSE & State Boards)

1. Age Criteria for School Admission in India — the National Picture

Search for the age criteria for school admission in India and you will usually get one confident number — “six for Class 1.” The reality is layered. NEP 2020 recommends 6+ for Class 1 and folds ages 3 to 8 into a single foundational stage, but a national recommendation is not a national rule: states are mid-transition, and the position in the 2026-27 cycle is not yet uniform nationally. Some states now enforce 6 for Class 1 through their own notifications; others still admit at lower ages under older orders; and every private school layers its own notice on top of whichever rule nominally applies.

Three layers decide any child’s admission year. The board layer: CBSE’s affiliation guideline runs the 3-4-5-6 ladder (Nursery, LKG, UKG, Class 1), and ICSE-linked schools follow similar school-set ladders. The state layer: Directorates of Education issue a fresh age notification each admission cycle — Delhi, Tamil Nadu, Karnataka and Maharashtra each fix their own cut-off dates. The school layer: individual schools may set stricter dates than either layer above them. The binding date for your child is whichever of these the school actually applies — in practice, ask the school first and work backwards from its notice.

State DoEs publish a fresh age notification each year — figures here follow the 2026-27 cycle; re-verify against the latest notification.

The 2025-26 and 2026-27 cycles did not move the board-layer guideline ages — an age chart for CBSE school admission 2025-26 and 2026-27 shows the same 3-4-5-6 ladder in both. What changes year to year is the state layer: notification dates shift, government resolutions are reissued, and schools republish their notices. That is exactly why the calculator above lets you pick the cut-off rather than hard-coding one date, and why every row of the table carries a re-verify instruction rather than a promise.

2. CBSE Age Criteria: Nursery, LKG, UKG and Class 1

CBSE does not conduct admissions — schools do. What the board provides is an affiliation-adjacent guideline that most CBSE schools follow when framing their own notices: Nursery at 3, LKG at 4, UKG at 5, Class 1 at 6, each counted as completed years by the school’s cut-off date. ICSE-linked schools run similar ladders with similar school-set variation, since neither board operates a central admission portal for everyday entry. The four rungs below unpack the guideline — and show exactly where the school-set variation bites.

Nursery — age criteria for nursery admission in CBSE schools

The age criteria for nursery admission in CBSE schools hover around three completed years by the school’s cut-off — most commonly 31 March, occasionally the session start. Delhi formalises the floor at 3+ by 31 March through the DoE’s entry-level norms; elsewhere the school’s own notice governs, and a minority of schools admit at 2.5+ with a deliberately play-based entry year. Nursery is the widest school-set variation rung on the whole ladder, so treat 3+ as the guideline floor and the school’s notice as the binding date — two CBSE schools on the same street can run different nursery cut-offs.

LKG — age criteria for LKG admission in CBSE schools

The age criteria for LKG admission in CBSE schools settle at four completed years by the cut-off. LKG is the rung where late nursery entries collide with the ladder: a child who enters nursery at 3.5 reaches LKG at 4.5, which schools accept; a child who skips nursery entirely is usually placed in LKG only if the age fits the school’s notice. A handful of schools fold nursery and LKG into a single entry point around 3.5+. Because every later rung shifts with it, entering LKG a year late moves the Class 1 year by the same amount — the calculator above shows each program’s printed session from the same birthdate, so you can see the knock-on before you commit.

UKG — age for UKG admission in CBSE schools

The age for UKG admission in CBSE schools is five completed years by the cut-off, most often 31 March. For children continuing within the same school the date is procedural; for direct entrants — families transferring between cities mid-ladder — schools commonly ask for five by 31 March plus the LKG completion record or transfer certificate. A few schools admit at 4.5+, a few hold a full five years. Confirm both the age and the paperwork before the admission window opens, because UKG vacancies appear irregularly and move fast when they do.

Class 1 — using an age calculator for CBSE school admission

Class 1 is the anchor: the CBSE guideline asks for six completed years by 31 March of the admission year, so the 2026-27 session expects a sixth birthday on or before 31 March 2026. Using an age calculator for CBSE school admission is genuinely useful here because schools diverge: some hold the 31 March line, some pull the cut-off earlier in the calendar, and state-regulated schools follow the state’s date instead. Enter the birthdate with the cut-off that matches the school you are targeting, read the printed session and the age at the cut-off, then confirm the school’s own notice — the guideline and the notice do not always agree, and the notice wins.

3. State-wise Cut-Offs: Delhi, Tamil Nadu, Karnataka and Maharashtra

State Directorates of Education publish a fresh age notification each admission cycle, and the four states below account for most of the queries parents type into search. The dates here follow the 2026-27 cycle; treat each one as the working figure for planning and re-verify against the current notification before you apply anywhere.

Delhi — 3+ by 31 March (DoE entry-level norms)

Delhi’s DoE anchors entry-level admission at 3+ as on 31 March, with nursery seats in private schools allocated through the point system each school publishes — distance, sibling and alumni criteria dominate, and the age floor is the one fixed input. The 31 March anchor frames the rest of the Delhi ladder by extension, though the detailed norms govern the entry level directly; admissions to LKG, UKG and later classes run on withdrawals and transfer certificates against the same age logic. A child born on 1 April misses the cut-off by one day and joins the following session’s draw.

Tamil Nadu — 5+ by 31 July (2022 government order)

The age criteria for school admission in Tamilnadu changed with the state’s 2022 government order: Class 1 entry at five completed years as on 31 July, with the academic session opening in June — so a child born in June turns five just after the session begins and still qualifies for that cycle. Many schools align the session to June accordingly, and LKG typically follows a 3+ by 31 July norm in schools that adopted the order. Transition-year adjustments and school-level practice have varied since, so confirm the current year’s notification and the individual school’s notice rather than relying on the order alone.

Karnataka — the 5 yrs 10 mths to 6 band by 1 June

Karnataka’s order frames Class 1 entry as a band — roughly five years ten months to six years by 1 June — rather than a single cut-off age, which makes the state unusual: eligibility can depend on which end of the band a school applies. The session starts around June, and the order has been revised in recent years, so the band’s exact edges move. The practical workflow mirrors every other state: read the current order or the school’s notice, note the date, and test the child’s birthday against it — the calculator’s 1 June cut-off gives you the working answer.

Maharashtra — age limit for school admission in Maharashtra

The age limit for school admission in Maharashtra is six completed years for Class 1, but the cut-off date is fixed afresh in each year’s government resolution (GR) — and it has moved between GRs, which is why the calculator above uses 1 June as a flagged working figure rather than a settled rule. Practical steps: find the current admission GR on the school education department’s site, note the exact date, and test the child’s birthday against it. Pre-primary wings attached to state schools publish their own entry ages in their notices, and those can differ from the Class 1 GR date.

4. Age and School Grade Chart India

Once a child is in, the ladder is arithmetic: one class per session, ages climbing one year per rung. The chart below is the standard track — ages at the start of each class for a child who entered Class 1 at 6. It is the quick reference behind most searches for an age and school grade chart India, and it doubles as a transfer tool: a child moving boards or states mid-ladder can be placed by age against this chart and then fine-tuned by the receiving school’s records.

Two caveats keep the chart honest. First, retention and acceleration shift every later row by a full session — a child who repeats Class 3 sits one year older in every chart row afterwards. Second, the chart assumes the CBSE-guideline entry (Class 1 at 6); a child entering at 5 under a state order runs the whole ladder one year younger. For a personalized projection from any birthdate, the school grade age calculator maps every class year at once, in either direction.

5. Sainik School Age Limits (Class 6 & Class 9)

Sainik Schools admit through the All India Sainik Schools Entrance Examination (AISSEE), and eligibility runs on an age window rather than a single cut-off: 10 to 12 years for Class 6 entry and 13 to 15 for Class 9, with the exact bounds defined in each year’s notification — recent cycles have anchored the computation to 31 March of the admission year. A candidate outside the printed window, even by days, is out for that cycle, which makes the age for Sainik School Class 6 the first thing to verify, before any exam preparation begins.

The Class 6 window is two years wide — unusually generous by Indian admission standards — and girls have been admitted at Class 6 entry in recent cycles under the same examination. The planning note: on the standard track a child sits Class 6 five sessions after Class 1, so a child who enters Class 1 at 6 lands inside the 10-12 window automatically, while a child who entered at 5 under a state order needs a check against the notification’s lower bound. Run the birthdate through the calculator above for the Class 1 session, add five sessions, then verify both ends of the window against the current AISSEE notification.

6. KVS and DAV Age Limits

KVS — age limit for KV school at Class 1

The age limit for KV school admission at Class 1 is six completed years as on 31 March, applied through the Kendriya Vidyalaya Sangathan’s online registration and lottery. KVS follows the 31 March anchor strictly, and the current admission guidelines — not older summaries — define the upper-age handling and any category-wise relaxation. For Class 2 upward, admission rides on vacancies and the transfer certificate, with the class-to-age fit checked against the same ladder. Because seats serve transferable central-government employees first, the age rule and the category priorities interact; read the year’s guidelines end to end before registering.

DAV — age criteria for DAV school

The age criteria for DAV school admission are school-set: the DAV network runs its own schools under state registration patterns, and there is no single network-wide date. In practice most DAV schools align to the CBSE guideline ladder — 3 for nursery, 4 for LKG, 5 for UKG, 6 for Class 1, completed by a 31 March-style cut-off — with regional variation around the edges. Treat the individual school’s admission notice as the binding document and confirm the entry age for the exact campus, since two DAV schools in the same city can run different cut-offs for the same program.

7. How Indian Cut-Offs Differ from US Kindergarten Dates

The US runs kindergarten on an age-5-by-September-1-style cut-off (the exact date varies by state) with a session that opens in August; India runs Class 1 on age-6 with a session that opens in April — or June — and a printed year that straddles two calendar years. The arithmetic difference is one full grade-label offset: a 6-year-old new to school in India sits in Class 1, while the same 6-year-old in the US sits in kindergarten or first grade depending on the birthday. Families relocating between the two systems hit this constantly, and international-school placement officers spend half their time explaining it.

The second difference is where the cut-off sits relative to the session. “2026-27” is one Indian cohort — April or June 2026 to March 2027 — with the age test at the back (31 March, before the session opens) or the middle (June/July, just after it opens); the US “2026-27 school year” is the same span but the test sits at the front (September). A child who misses India’s 31 March line waits for the next printed session exactly as a September 2 birthday waits a full US year. For the state-by-state US dates, see the kindergarten age cut-off dates by state table, and for the wider map, the school age calculator by country.
