In Denmark, the educational system adopts a national policy that prohibits the categorization of students into ability groups until they turn ten years old. This approach allows children to develop at their own pace during the formative years, emphasizing equality and inclusivity in learning environments.

By delaying selection decisions based on perceived ability, Denmark acknowledges the natural variations in maturity among children of different ages. This delay helps ensure that educational opportunities are equitable and that students are not unfairly judged or placed into tracks based on early developmental differences.
