Age Grade Calculator: What Class Should My Child Be In? India School Guide

• In India, the standard school entry age is 6 years for Class 1 — children born between June 1 and May 31 of the previous academic year are eligible for the new academic year starting April/June.
• Most Indian states now follow NEP 2020's 5+3+3+4 structure (Foundational, Preparatory, Middle, Secondary) instead of the traditional 10+2 structure — though implementation is still rolling out.
• Age-grade mismatch happens when students start school late, repeat a class (detained), or change boards/systems (CBSE/ICSE/State board) — our calculator accounts for all these scenarios.
• For international school systems: the calculation differs significantly — US kindergarten entry at age 5, UK at age 4–5, Singapore at age 6 — all with different academic year start dates.

Use our free Age Grade Calculator to find the expected class/grade for any child's age, in any school system — India (CBSE/ICSE/State), US, UK, or international.

India School System: Age to Grade Chart

Standard Age-Grade Mapping (India, NEP 2020 + Traditional)

Academic year: April/May to March (most states) or June to April (some states like Tamil Nadu, Karnataka) Entry age for Class 1: 6 years as of June 1 (or April 1 in some states)

Age Cutoff Rules by State/Board

The entry age cutoff date varies by state — this is a critical detail many parents miss:

State / Board	Class 1 Entry Age	Cutoff Date
Delhi (DDA/DOE schools)	Completed 6 years	March 31
Maharashtra	Completed 6 years	June 15
Karnataka	Completed 5 years 6 months	June 1
Tamil Nadu	Completed 6 years	June 1
Kerala	Completed 6 years	June 1
Uttar Pradesh	Completed 6 years	March 31
CBSE (private schools)	Completed 6 years	Typically March 31 or April 1
ICSE (CISCE schools)	Completed 5.5–6 years	Varies by school

Example: A child born on April 15, 2019:

• In Delhi (cutoff March 31): Turns 6 on April 15, 2025 — NOT eligible for Class 1 in April 2025. Eligible from April 2026.
• In Karnataka (cutoff June 1): Turns 6 on April 15, 2025 — IS eligible for Class 1 in June 2025.

The same child is in different classes depending on the state! This is one of the most common sources of confusion when families relocate across states.

NEP 2020: The New Structure Explained

The National Education Policy 2020 restructures schooling into 5+3+3+4:

Stage	Classes	Age	Focus
Foundational	Nursery–Class 2 (5 years total)	3–8 years	Play-based learning, mother tongue, foundational literacy
Preparatory	Class 3–5 (3 years)	8–11 years	Formal subjects begin, activity-based
Middle	Class 6–8 (3 years)	11–14 years	Experiential learning, vocational exposure
Secondary	Class 9–12 (4 years)	14–18 years	Multi-disciplinary, critical thinking

Status of implementation (2025): NEP 2020 is being rolled out gradually. The 5+3+3+4 framework is being adopted by NCERT and central schools (Kendriya Vidyalayas, Navodaya Vidyalayas, CBSE). State schools are in various stages of transition.

Key change for parents: Under NEP, Class 1 is now part of the "Foundational" stage alongside kindergarten — not a sharp transition. This means Class 1 continues play-based learning rather than immediately shifting to formal academics.

Age Grade for International School Systems

For families relocating internationally or comparing systems:

Country	School Start Age	Grade Name	Age 10 Grade	Age 15 Grade
India	6 years	Class	Class 5	Class 10
USA	5 years (Kindergarten)	Grade	Grade 4	Grade 9
UK	4–5 years	Year	Year 5	Year 10
Singapore	6 years	Primary	Primary 4	Secondary 3
Australia	5 years	Year	Year 5	Year 9
UAE (Indian Curriculum)	6 years	Class	Class 4	Class 9
Canada	5–6 years	Grade	Grade 4–5	Grade 9–10

India to US grade equivalency:

India Class	US Grade	Typical Age
Class 1	Grade 1 (or Kindergarten)	6 years
Class 5	Grade 4–5	10 years
Class 10	Grade 9–10	15 years
Class 12	Grade 11–12	17 years

Note: Because US school starts at age 5 (kindergarten) and India at age 6 (Class 1), an Indian student moving to the US may be placed one grade lower than their Indian class number — depending on the school's assessment.

Age Grade Calculator: Accounting for Variations

For Detained Students (Failed + Repeated a Year)

If a student repeated a class once: Expected age = Standard age + 1 year A 16-year-old in Class 10 (standard age 15) has likely repeated one year.

For Early Entrants

Some private schools admit students at 5 years 6 months for Class 1, making them a year younger than their standard cohort: A 14-year-old in Class 10 = entered school at age 5 or 5.5 years (early entry).

For Gap Year Students (Between Class 12 and College)

After Class 12 at age 17–18, many Indian students take 1–2 year drops for JEE/NEET preparation: A 20-year-old entering first year engineering is typical — not unusual.

Right to Education Act: Age and Admission

The RTE Act 2009 guarantees free and compulsory education for children aged 6–14 years (Classes 1–8). Key provisions:

• No entrance test or donation for admission to any school for Classes 1–8
• Age-appropriate admission: Children above 6 years who haven't started school can be admitted to age-appropriate class (not necessarily Class 1)
• 25% EWS seats: All private unaided schools must reserve 25% of seats for economically weaker section children
• No detention till Class 8 (under original RTE — some states have since amended this to allow detention from Class 5 or 8)

FAQ

What is the minimum age for Class 1 admission in CBSE schools?

CBSE schools typically require a child to be 6 years old as of March 31 of the admission year. However, individual schools may have slightly different cutoffs (some use April 1). CBSE's official guideline is 6 years, but state governments may set their own cutoff dates for schools in their jurisdiction.

Can a child be held back or detained in India?

Under the original RTE Act, no child could be detained (failed/held back) until Class 8. However, the RTE Amendment of 2019 allows states to conduct examinations in Classes 5 and 8, with states empowered to detain students who fail if state policy permits. Currently, different states have different detention policies.

My child is 7 and hasn't started school — which class should they join?

Under RTE, children should be admitted to the age-appropriate class. A 7-year-old would typically join Class 2 (if already 7 as of June 1) or Class 1 (if turning 7 later in the year). The school may conduct a brief assessment but cannot deny admission or charge fees for Classes 1–8.

How does CBSE Class 10 age compare to US 10th grade?

CBSE Class 10 students are typically 15–16 years old. US Grade 10 students are also 15–16 years old. The two systems align well at this level despite different starting ages — because US Kindergarten (age 5) and India Class 1 (age 6) have a 1-year gap that narrows by high school due to early grade repetitions and system variations.
