We are in a similar position. I have some achievement scores indicating DS might be in a position to test into DYS. But we haven't done so. We have a vibrant local GT community and we're homeschooling, so I'm not seeing any pressing need to make that leap. Especially considering what we'd have to pay to test around here. DS doesn't seem to be 2E or anything like that, so I'm not worried about what we'd find. Now that I've spent a few years reading on this subject and a year and a half homeschooling, I feel like I have a pretty good idea about him and where his strengths and weaknesses lie. I actually have a 5 year old I'm more curious about right now! But we'll wait it out on her too and see what the next couple years bring (she's also homeschooling).
I personally think curiosity is sufficient reason if you have the funds and desire though!
