I understand that homesschooling can be the best option, depending on the needs of the child and the ability of the parents. Many times it works out very well.
But in my experience, JW parents are perfectly awful at it - in no sense at all are they "teachers". Their kids, in the vast majority of cases, emerge from "school" as emotionally stunted beings who simply are unable to cope with life and completely unprepared to make a living.
The website I pointed to is, as Cofty noted, astonishingly amateurish. [God of your choice] help the kids whose parents sign them up for such an "education".
I also found extremely disturbing the implied threat of disfellowshipping for kids who "misbehave". Chilling, to say the least.
