I'm homeschooling/unschooling DS7 - who is 2e and eg/pg. We live in a non-gifted friendly state so public schools are not an option.
DS has been in two private schools - one structured with workbooks and typical curriculum; the other more Montessori. So we come to homeschooling by default and running out of formal school options.
At the structured one gifted school, he rapidly accelerated through pre-k/k/1st grade within 2 1/2 months. The headmaster then refused to bump him to 2/3rd grade class. He also refused to accommodate him in the school. He said that eg/pg kids don't fare well there. Great. We then decided to try our luck at the Montessori-type gifted school.
At the Montessori-type gifted school, DS was initially happy because the school was a one-type schoolhouse situation with 30 kids from pre-k to 8th grade. However, he was the only eg/pg kid in the school and it was awkward at times. Ds was able to accelerate in reading from phonics to 5th grade. But the math situation was a disaster and the school basically dropped the ball there. He didn't do much beyond addition, which became a problem. Talk about a headache
Today I'm somewhat doing what HowlerKarma says. We use a general curriculum guide series, which gives DS some structure and the basics. We use the HECK out of our local library system too; love that one. DS spends a lot of days reading various books or playing with his Legos or other stuff. Downtime is important too with these kids.
Like HowlerKarma, I've also found that homeschooling DS is somewhat easier than dealing with schools. For one, you don't have to contend with school personnel or trying to get them to remotely accommodate your child. Second, you've got tons of flexibility in terms of learning content and a child's pace, but also with social interactions, which can be a bigger issue with these kids. Third, a lot of the homeschooling is actually self-directed. Fourth, you can potentially have more of a handle on your child's needs with homeschooling than I ever would have imagined.
I've heard on this forum and on other lists that eg/pg can get accommodated at public or private schools. So it's possible. But I think there's tons of variables involved for an eg/pg child to attend public school regardless. It really depends on where you live, the school district, the teacher, the curriculum, the other students, your child, and on and on. It's often Russian Roulette from year to year.
At the end of the day, you're the parent and only you can truly advocate for your child and what they need. I know this too well as a 2e parent, but it's equally true as an eg/pg child. Remember, too, that homeschooling may not necessarily be for life. Remember, too, you could always try out a school and then pull them or try out homeschooling and then put them in school. Nothing is etched in stone and other options may present themselves in the future.
Sometimes it helps to think in terms of least-worst situation.
