I remember the principal commenting more than once that she forgot that he had already skipped a grade. Once the school sees how successful a grade skip has been, things get better. They must see for themselves that their long-held beliefs (skips are not a good idea) are not true for everyone.
I think that this is the hallmark of a successful skip. Dd14's teachers often said the same to me in middle school (she skipped the last year of elementary) and it came up once with a high school teacher who had assumed that she was one of the oldest in grade not younger. We find a lot of educators with the belief that being older is invariably better and who are rather surprised when that doesn't hold true. In fact, I recall when we were ready to register dd14 for kindergarten (her bd had her starting just before her 5th bd), the principal telling me that the "younger kids invariably fail" and that her age would become more and more problematic as she got further into school and she fell further and further behind due to being too young. Redshirting is not uncommon with kids whose bds are in the summer and early fall here.
That attitude tends to lead toward educators making assumptions that kids who are succeeding socially and academically must be older not younger and certainly not grade skipped. It is good, IMHO, for them to realize that their assumptions may not always be true.
