In the Netherlands, school entrance is possible at the age of 4. Approximately 99% of all children start school when they turn four years old. Entrance is possible at any day of the year, except of course for weekends and school holidays. However, children in the Netherlands are obliged, from the moment they reach the age of 5 until the end of the school year they turn 16, to participate in full-time (five days a week) education. After the age of 16 there is the qualification requirement. The qualification requirement is for all young people until the age of 18 without a starting qualification. The aim is that all young people have at least a certain level of secondary education.
