[Age on starting school and school achievement].

According to a medical check-up on the whole group of school beginners for one year in the town of Görlitz and considering the results of their first school year, the authors observed that the age on starting school has a very important influence on school achievement. While girls are better able to compensate for developmental retardation, it is advisable to postpone the admission of very young boys for one year in doubtful cases or to provide individual coaching.
