I asked the principal (with some gifted experience) if she would test my DD6 first grader. She said, "that sort of request needs to come from the teacher and NO the school can't test everybody. I'm thinking she needs more challenge and her brother was tested with 140 IQ so that would be reasoning enough. The school tested DS becuase of behavior.
Just ask the teacher to refer you DD for testing. You can say that you are worried about DD's 'self esteem' if DS gets all this special accomidations and she doesn't - you don't have to mean it! 'Self esteem' is a hot button issues with most schools.
Do you have any stories that support the 'she needs more challenge' statement? If so, I would share those because I think that this is the 'better' argument, even if the schools won't get it.
Just ask!
