Ds6 has been stalled at the same level since the beginning of follterm 3 (NZ has 4 10 week terms). He is about 18 months ahead. They will not let him go further now because they insist that having missed the cut off by 5 weeks that he does 7 terms in year 1 followed by year 2 and he is 2 levels of the maximum he is allowed by the end of next year.
In your case since they are allowing a skip i would leave it for now. Let her read lots at home and next year she will surge ahead in the higher class. The last 5 weeks of the year seem to be less academics anyway and everyone will pat your head and ignore you because they are too busy.
