Detention (nablijven or Strafstudie) is a thing in the Netherlands and after school plans other than the doctor or the dentist are ignored by the teacher. Most School regulations state that pupils should be available for school between 8am and 6pm.
Those who dare to ignore detention will see their detention doubled. If the detention is still ignored expulsion is an option.
Being late will lead to detention. 10 x too late will land you before the magistrates. Not the parents but the pupil
