Hi Ange,
Welcome! And congratulations on getting into DI!
I share your pain of having to pay testing out of pocket. We separated the testing dates to "spread" the cost over time. We decided to test both of them partly to be "fair" (what is fair anyways, right?), but mainly because we hope to use these scores to advocate for their educational needs. (And honestly, I really wish we had test DD6 earlier.)
Sounds like your children are both very bright. Any chance that you might be able to use the testing info for other purposes? (such as applying to DYS and/or for school placement, etc.)
How old are your children? For us, DD6 and DS4 both think of the testing as playing games and puzzles with Mommy and Daddy's "friend." They took the tests, went to McDonald's for lunch, then off to school. They never asked, not even once, of the result. So, depending on your children, you may not need to do much explanation at this time.
And, as far as comparison, what are your concerns?
Also, you might be interest in this recent discussion on families with both DYS and non-DYS children and how they handle the situation:
