We chose to homeschool when we realised that the 1 grade skip offered would not be enough for long enough.
Our son would have been in a rage if he had gone through the process of learning to sit for longer, write more and for longer and do extra work (that he already mastered) and then figured out that it was nothing really new in terms of learning. I don't think I could have coped with the fallout.
In your situation if you cannot homeschool then approach the school and ask for appropriate placement testing, or start searching for a more understanding school.
