My own daughter was at an international school that thought along these lines. When some English parents questioned the head about their child not reading at six,he replied that the school had taught the child, and all the others, to swim well by the age of five! He added that being able to swim "could save a child's life, which was far more important". Reading would come in due time.
In fact, the school was following foreign, 'international', practice in teaching reading. (The swimming, for which there were constant prize- givings to little tots, was the idiosyncratic plan of the head). The school preferred to concentrate on developing what we now, apparently, term 'social skills' in young children (together with perfect formal manners, which were very French in their nature!)
