- If the child returns at 17:00 from the school, returning home at 17:30 or so, there is less family-time before the child retires to sleep at ca. 19:00.
- If the child and parents are interested in development of extra-curricular skills like specific music instrument, specific sport etc., over and beyond what the school officially offers.
One compromise would be to offer the mandatory lessons (Pflichtfächer) in the morning (till 12:00 or 13:00), and the optional ones in afternoon. Parents and children can opt to go to full-day or half-day school.
