Seems to be a spectrum of options, from one full time teacher, 2 half-time teachers, and/or several specialists. The latter seem more flexible, but require more management. Still, I seem to be spending 5 hours a week driving my children around, and this approach would probably still need 5 hours but with less of it driving and more of it acting as an administrator of the team of tutors.

Valuable feedback that in fact a child does not really get or need 8 or 6 hours a day of instruction, probably more like 3. This could probably increase as they get older though.

I think the next step for me would be to follow aquinas lead and think about the curriculum and weekly and annual schedule. One more aspect, I would want to build in one or two or three tests a year to measure progress. Not sure which test though.

Bay Area has an excellent gifted home school group. I am sure if I connect with them they work towards solutions on peer group. They probably also have some co-ops and some thoughts on home tutoring.

Portia, Ivy, would your child return to the mainstream at college? FWIW my DS7 and DD9 are probably at the low end of PG and may try for the Young Scholars program some time.
