How is school starting age calculated?
Most countries require a child to reach a minimum age (often 4, 5 or 6) by a fixed cut-off date. If a child reaches that age before the cut-off, they start school that year. If their birthday falls after the cut-off, they must wait until the following year's intake.
What is the school starting age in the UK?
In England and Wales, children usually start Reception in the September following their 4th birthday, meaning they turn 5 during their first school year. The standard cut-off date is 1 September.
Does the cut-off date vary in the USA?
Yes. Kindergarten cut-off dates differ significantly by state, ranging from as early as 1 August to as late as 1 December. Always check your specific state or school district's enrollment policy for the exact date.
What about Canada's provinces?
Rules vary by province. Ontario commonly uses a 31 December cut-off for Junior Kindergarten, while other provinces may use different ages and dates. Use the custom fields to match your specific province.
