Given the significant cost of Jewish day-school tuition (at least in the US) and the negative experience that some students have in those day schools (I'm speaking from my own experience as well as those of friends, my children, and their friends). I would like to know why more orthodox Jews do not home-school? Are there halachic reasons? Has any research been done to see if there are social taboos that are in play? Other reasons?
In general, it is very hard for a Jewish family to home-school their sons in particular because the mothers do not normally have the background to teach them Torah, and the fathers normally work / are in kollel and are therefore unable to spend their time teaching them.
