My DS had a mid-year skip from 1st to 2nd but it was really more like a 2 year acceleration because he skipped into a GT cluster that was working at a 3rd grade level overall with individualized reading groups. In theory, they will work at a 4th grade level in the coming year.

We will see how it goes this year because they reorganize the cluster grouping every year. He finished ALEKS 4th grade math in 10 hours this summer so redoing it again would be an okay review but if they drop back down to 3rd grade he will need additional subject acceleration.

At his pace of learning, I can see that an additional skip in the future is probably going to be necessary but we will try to avoid it if at all possible. DS is happy socially in his current grouping and seems to be a really good match.
