In France, children start school at three years old (although it is not compulsory until six years old). A comparison between my daughter (educated in France) and her cousin (in the UK) at exactly 4 yrs 9 1/2 months old showed that a British education gives kids the tools they need to read and write much more quickly.

In August 2013, the age at which children are required to begin school in Illinois was lowered from age 7 to age 6.The new age requirement will take effect beginning with the 2014â2015 school year. (Public Act 098-0544).ccording to the Illinois School Code, children who will be 5 years old on or before September 1 may begin school. Based upon an assessment of a child's school readiness, a school district may choose to permit a child to attend school prior to that date, or it may choose not to do so.
