I know it is premature but the reason I am ringing this up is for 2 reasons.
1. Just to give me an idea if I will end up home schooling or at least partly home school one or two kids...:-/
Although I am certainly not opposed to well done homeschooling that broadens a child's world rather than narrowing it, and did homeschool one of my girls for a while, I do want to put in the plug that all PG kids don't absolutely have
to be homeschooled.
We were essentially given that suggestion by the GT coordinator at the time @ the district where my dds were attending school when we presented them with IQ and WJ scores for dd13 (she was 7 at the time). She told me that the district was philosophically opposed to meeting her needs, she wouldn't last long in public schools, and asked if I had considered homeschooling. While your dc may well be more gifted than mine, I don't think that the IQ number alone is the prescription for specific schooling situations.
My youngest, no matter what the IQ, would not have thrived with homeschooling given her extremely extroverted nature unless I had been able to find a very active homeschooling group with daily meetings. I seriously considered homeschooling her b/c she is 2e and we had a terrible time getting her needs met in school, but we do have a situation at the moment that is working reasonably well if not perfectly. My oldest is also reasonably well situated although again, it isn't perfect. That has required a combo of grade skipping, subject acceleration, AP & honors courses, and extracurriculars.
Even with the admission that it has been a challenge and not perfect, I don't think that homeschooling permanently would have been perfect either. Sometimes it is a combo of trying different things, remaining open minded to changing course if it really isn't working, and realizing that perfect often doesn't exist.
