A child that is a fairly advanced reader in Y1 - ORT 8 or 9 for example - is probably reading at this level because they've had more practice at home than others.
I know there is more to it than decoding but a child will usually become familiar with all the other aspects (comprehension, expression etc) if they've had lots of time to figure it all out and an adult's support.
So apparent 'talent' at this stage is really only hidden practice? Someone said that their child taught themselves aged three but these children are clearly unusual. This is what made me think.
They all tend to catch up and we are out of the infants now but surely, generally speaking the more practice a child has the better they get? Or am I missing something? Am not sure it's widely seen this way.
