I and all of my siblings were tested on the LM, back in the day, but none of our children have been, other than incidental OLSATs at school, mainly because the numbers matter very little. If we spend enough time with them, children will tell us by their presentation what they need, and meeting their needs is what matters.
Of course, as a side note, I've administered enough tests to have a reasonable idea of where the kids fall on the curve. Not that I could name a number by eyeball. There is a famous anecdote (well, famous in assessment circles!) about David Wechsler being able to pin the FSIQ of pretty much any kid in less than ten minutes, with a couple of choice questions and his clinical observation. It appears to be legit, as it concerns Alan Kaufman's (KBIT, KTEA, WISC-IV guy) young daughter.
They have had some achievement testing, but that was mostly because I was trying out my new test kit!
