Comment Boat schooling (Score 1) 700
I cruised a large sailboat for a few years in the Paciifc and the Atlantic. We met a lot of kids who were being "sea schooled" using one of the fine correspondence schools that caters to cruisers. These were happy, well adjusted, kids whose basic education included multiple cultures and languages, a deep sense of responsibility as crew, and plenty of socialization experiences.
Many of these cruisers "swallowed the anchor" eventually and put their kids in public schools to meet the various state qualifications for university entry. According to the teachers in the San Diego public school system that I spoke to, these kids were usually a grade or two ahead and far more mature that their peers in age.
This is different from some parents that are sheltering their kids from protective or religious reasons, but it points to the fact that the quality of home schooling depends on the parents, the kids, and the actual curriculum. Generalities will be misleading.
