Go back and read post #194.
I did. I don't think the situation applies here. In Massachusetts, home schooling is actually pretty common, with plans and testing schedules approved by the local school committees. Some might be better about leniency than others, but the administrators, I'm sure, would just as soon get someone's kids out if the parents are going to be a constant irritant.
Students with IEP's (individual education plans) are often given home study or paid-for alternative school programs if that's deemed appropriate. I'm not even sure the school loses the per-pupil expenditure, since the home-study students can take some courses in school and be involved in activities.
I know you all assume because it's Massachusetts that thought-Nazis don't want these two children to escape group-think. But, the reality is that alternatives are pretty much respected, unless education isn't happening.
