We have only recently come across a problem that we hadn't anticipated in advance of the grade skip. In math competitions, like Math Olympiad or elementary Math League, DS is competing with other gifted kids. Last year, he would have won an award at the state level for scores as a 5th grader, but because of the skip, he is a 6th grader. So he missed out by two points. As a gifted 5th grader, he still knocked the socks off of the competition. Because some families locally are huge in red shirting, he was competing against kids that were two, sometimes three years older and also gifted.
