I answered the poll but there wasn't really a choice that fit our situation. We did a full grade acceleration (plus some additional acceleration for math after some time had went by), and it worked well for a couple years, then the negatives started outweighing any positives, so I checked that "it was not helpful". I am not sure at this point whether we will try to "undo" the full grade acceleration. The reason why the negatives seem to now be outweighing positives is because of the EF issues and being diagnosed 2e since the acceleration. It wasn't a "horrible" decision, and it did help for a couple years, but I don't know that it was the right thing over the long term. Of course we don't know what things would have been like if it had NOT been done...maybe worse or there would have been other problems to deal with.
