We were in the same boat around age 4 as well. We knew something was going on, but I was really floored when the psychologist we consulted about what we were perceived were real issues (he had zero fear, was a total escape artist and at that point we had alarms on all windows and doors including his bedroom door!). She suggested we test him, but wait until 4 for the WPPSI but she thought he would hit the ceiling and need to be retested after 6 anyway. We thought about it, contacted the GDC in CO, and then after realizing homeschooling was our only option we hooked up with a gifted homeschooling group.
We finally decided to wait until he turned 6 because the pressure of school was off at that point since we were homeschooling. The public school had already admitted they couldn't accomodate him, and we had someone with GDC suggest that there wasn't a school in our area that could likely accomodate his needs at any time so we became quite comfortable with our situation rather quickly. My little man turns 6 next week, and we have a local tester chosen who was recommended by a couple of PG families and he will be tested this summer. We're having him WISC and SBLM tested for good measure.
Thanks for sharing your situation. How did you determine that homeschooling was your only option (was no gifted program, etc)? I have a lot of concerns about the need to potentially homeschool our son. I have a career that I really don't want to walk away from, so I am hoping that my planning ahead will help us to find some options.
I also stuggle with the fact that my husband, who I believe to be PG, made it through the public school system ok. I will say, the first time I ever saw him work for anything (in terms of school) was when he showed up at a top university to start his PhD. It was a very rough first quarter for him. For the first time he had intellectual peers and had to work for his A! So it makes me wonder if I am just over reacting and that our son will be just fine in the public school system too...
