No generalized approach can be taken to this iisue, apart from saying "It depends..." Your son can certainly proceed to first grade and see how much progress he can make in learning to read. Now, in saying this, I'm assuming he is in possession of 'readiness skills' for first grade. Is he? If so, go ahead with his promotion. He can always repeat first grade (where the major academic task is learning to read) if he is struggling with reading as first grade nears an end. Unless achild is very, very immature and not in possession of readiness skills, repeatingkindergarten is not necessary.
