Yes, we had DS tested (based on the rather common here experience of being told he wasn't gifted and just a behavioral problem in a rigid classroom where he was not learning a single new concept or fact).
DH, no, he doesn't know, but has vivid memories of being highly bored (although he was a "good student" and studied, unlike his wife) in a pretty good school system. I would think somewhere in the gifted range, certainly. Excellent memory, quick math ability, catches on to most subjects right away.
My school had no g&t programs. I don't know my IQ, but based on other tests I qualify for MENSA, for whatever that is worth. Throughout high school I rarely studied (which was a problem once I hit college and actually needed those skills) and was either a teacher's favorite or a PITA for those I deemed boring (was not afraid to challenge them). I must have been a delight.
I knew I was smart, but didn't think I was all that smart (always knew others with better grades or scores). Professionally, especially within the last few years, when I've had anonymous feedback surveys, I've been surprised by the number of comments about my intelligence. I'm not saying that to brag and hope it is a safe comment here, it's just odd to get that from coworkers ("scary smart" is one of the comments that stands out) when I've tried so hard to fit in... for so many years.
