What Age Do Kids Start School Around the World? By Country & Age

“Starting school” can mean three things: when children may attend, when education becomes compulsory, and when primary lessons begin. France requires education from age 3, for example, but its first primary grade starts at 6.

Compare your child’s age across all 52 places, or start with the summary of places below.

School starting ages by country: a quick comparison

The two ages below answer different questions. Primary uses the international classification for comparing education systems. Required means the age when the law first requires education, which may be a preschool year.

The US row begins with first grade, usually at 6. Kindergarten usually comes a year earlier and is part of elementary school. England’s row begins with Year 1 at 5, but most children enter Reception in a primary school at 4. Those earlier classes are classified as pre-primary for international comparisons. The label describes a stage of education, not the building children attend or whether they learn to read there.

Finland and Sweden normally require a pre-primary year at 6, before primary at 7. Finland also permits a corresponding activity. France requires instruction from 3, usually in nursery school. US compulsory ages vary by state. Australia also varies; the row here is New South Wales, where eligible children may start before 5 but must be enrolled by 6. Each place’s sources and birthday rules are in the full comparison below.

Some systems use the year a child turns an age, so children may begin before their birthday. A country-level age is a starting point for a move, not an individual placement decision.

Kindergarten isn’t the same word everywhere

In Germany, kindergarten is early childhood education. In the US, it is a school grade with a reading curriculum. The name alone won’t tell you what children do there.

UNESCO’s shared classification, ISCED, makes international comparisons possible. Level 0 means early childhood education, including pre-primary. Level 1 means primary school, where systematic teaching in reading, writing and math begins. Local school names and buildings do not always match those categories.

Finland shows why that matters. Its required pre-primary year, or a corresponding activity, normally starts at 6. The day usually lasts four to five hours. Primary school starts at 7. Families can access childcare much earlier, from about 9 months, and most children attend early childhood care well before 6.

“Finland starts at 7” describes primary school. It does not mean children spend seven years without group care or early learning.

The same word can also hide an earlier primary start. In New South Wales, Kindergarten is the first primary year. In Germany, Kindergarten comes before primary. If you are moving, ask for the local class name, its birthday rule and what children learn there. Translating the name alone can put you a year off.

Which countries actually start school at 7?

The OECD’s 2023 comparison lists nine systems where primary school starts at 7: Bulgaria, Estonia, Finland, Indonesia, Latvia, Lithuania, Poland, South Africa and Sweden.

Our tool shows seven of those nine at 7. Bulgaria is not one of its 52 places. South Africa appears at 6, because the tool counts a child’s age on the first day of school. South Africa’s school year starts in January, so most children are still 6 when Grade 1 begins (our conversion).

Their earlier years work differently:

• Finland and Sweden: Most children attend a required preschool year at 6 before starting primary at 7. In Finland, a similar group activity counts too. Sweden allows delays only in special cases.
• Estonia: Children start primary the year they turn 7. Towns must offer childcare from 18 months and preschool from 3 if families want it.
• South Africa: Primary starts at 7, but a required Grade R year at 6 was added in late 2024 (taking effect that December).

Sweden is shifting its model. Starting in 2028–29, its preschool year becomes part of a ten-year basic school starting at 6. We have not found an updated international classification for that change.

Which country starts school the earliest?

Northern Ireland has the youngest usual compulsory primary start among the 52 places we checked: age 4.

Children who turn 4 from September 1 through the following July 1 usually begin in the next school year. Those turning 4 from July 2 through August 31 start in September after their fifth birthday. Children born April 1–July 1 can defer a year. Children born before April 1 whose expected birth date was after April 1 can also qualify under the local rules.

France, Hungary, Israel and Mexico require early education from age 3. That includes pre-primary education, so it is a different comparison.

France made instruction compulsory from 3 in 2019. In 2018, before the change, 96.6% of 3-year-olds were already enrolled. The share rose to 97.3% in 2019, then returned to its 2018 level in 2020. A later public evaluation found little effect on enrollment.

In the Netherlands, children may join a primary school from their fourth birthday, but attendance becomes compulsory at 5. In Ireland, it is compulsory at 6, though most 5-year-olds already attend infant classes. The share of Irish junior infants aged 4 or younger fell from 47.3% to 19.5% between 1999 and 2019.

Those are three different measures: an open door, a legal requirement and the age families actually choose.

Which country starts school the latest, by age?

Age 7 is the latest usual primary starting age in our 52-place comparison.

It is shared by Finland, Sweden and several other systems, rather than one country alone.

The answer changes if you mean the latest legal requirement. Estonia and Indonesia put the usual compulsory start at 7. Finland and Sweden normally require earlier pre-primary education at 6. US requirements vary from 5 to 8 by state, so a single national US age would hide the difference.

These are the places and rules we checked, not a census of every education system in the world. A family’s ability to delay entry, or a child’s placement after a move, can also differ from the usual starting age.

What about Europe as a whole?

Europe has no single starting age. In our count of the 42 systems in Eurydice’s 2026–27 table, full-time compulsory education begins at 6 in 22 systems. Belgium’s three language communities count separately.

France and Hungary begin at 3. Bulgaria, Switzerland, Greece, Luxembourg and Romania begin at 4; Cyprus at 4 years 4 months. Ten systems begin at 5: Austria, Belgium’s three communities, Czechia, Latvia, Malta, the Netherlands, Serbia and Slovakia.

Estonia and Croatia appear at 7 in the full-time column. Croatia also requires a part-time preschool program at 6. Estonia is the only one of these 42 systems without an earlier compulsory stage. These are the table’s usual cohort ages; Estonia’s October 1 cutoff means some children are still 6 on their first school day.

Primary school starts at 7 in nine of these European systems: Bulgaria, Croatia, Estonia, Finland, Latvia, Lithuania, Moldova, Poland and Sweden. This list differs from the OECD list because the two sources cover different places.

The UK is outside this Eurydice table. England requires education from the term after a child’s fifth birthday. Denmark and Norway both start primary school at 6, so “Scandinavia starts at 7” is not an accurate rule.

What age is “primary school,” anyway?

• Internationally: primary usually begins between 5 and 7 and ends around 10–12. Lower secondary, roughly middle school, generally starts between 10 and 13, most often at 12.
• England: Reception covers ages 4–5; Year 6 covers 10–11. Year 7, at 11–12, is secondary school.
• United States: grade ranges vary by district. In 2011–12, 38% of public elementary schools ended at grade 5, 16% at grade 6 and 10% at grade 8. International tables classify US kindergarten as pre-primary.
• California: kindergarten usually starts at 5 and first grade at 6. Adding a year per grade gives about 10 at entry to grade 5, 11 at grade 6, 13 at grade 8 and 17 at grade 12. These are our calculated entry ages, not end-of-year ages or separate state eligibility rules. Local schools group the grades differently.

What time does school actually start around the world?

We did not find a comparable worldwide bell-time table.

Some figures are legal limits; others are measured averages or local schedules. Keep those differences in mind when comparing them.

The US numbers come from a federal school survey, not today’s schedules. The American Academy of Pediatrics recommends 8:30 a.m. or later for teenagers.

Riyadh’s 6:30 lesson time was the earliest current official schedule we confirmed, not a proven world record.

The two philosophies behind all of this

The OECD’s 2006 early-education report describes two broad traditions. One emphasizes readiness for school. The other, common in Nordic and Central European systems, treats early education as wider preparation for life.

Both include early literacy. They differ in how much time children spend on open-ended play and adult-led lessons. England combines a mostly play-based early-years framework with phonics teaching from Reception, at age 4. France’s primary reading curriculum begins in CP, its first grade, at 6.

US public-school kindergarten became more academic between 1998 and 2010. In the study’s public-school sample, 31% of kindergarten teachers said children should learn to read in kindergarten in 1998; by 2010, 80% did. Classrooms offering at least an hour of child-chosen activities fell from 54% to 40%. These are changes in reported beliefs and practice, not proof that the shift helped or hurt children.

Does starting later actually help kids?

The evidence is mixed. It depends on what researchers measure and what children do during the extra year.

A Danish study compared children around the school-entry cutoff. Starting a year later reduced mothers’ reports of inattention and hyperactivity at 7, with effects lasting to 11. The estimate came mainly from girls because boys were less likely to follow the cutoff. The sample was wealthier than average. In Denmark, most children attended play-based public care before school, so delaying meant more time in that setting. The study cannot answer whether delaying helped grades or test scores, or predict the effect of a family choosing to delay elsewhere.

A Norwegian study found a small IQ advantage from starting younger, measured in men at military conscription around age 18. Starting age barely changed completed schooling, and an early earnings difference had largely faded by 30. Among women, starting younger raised the chance of teenage childbearing.

Across 55 countries, 2006 PISA reading results at age 15 had no significant link to school starting age after accounting for wealth. That comparison cannot isolate the effect of one country’s age rule.

In a New Zealand study of 287 children, children taught reading at 5 initially led Waldorf children taught from about 6½. The gap had closed by 11. A separate comparison in the same paper involved 83 older children. The groups were not randomly assigned. The researchers warned against applying their findings beyond these advantaged samples or treating them as proof that reading should wait until 7.

For a parent, “later is better” leaves too much out. Ask what the extra year would contain and what support the receiving classroom offers.

For a teacher or school leader welcoming a child from another country, the starting age alone leaves out their experience. A 6-year-old may arrive from a primary class, a required preschool year or an optional room. Ask which class they attended and what was taught before assuming their age tells you their reading level.

What California does with the same three clocks

California offers free, optional TK to children who turn 4 by September 1. Kindergarten is also optional. School attendance becomes mandatory at age 6 under Education Code 48200.

The California preschool and TK guide covers costs and eligibility. The compulsory-age guide explains attendance and first-grade placement.
