I’m talking from a US perspective, but I work in an education adjacent field that reviews a lot of homeschool student’s academic records from across the country. IMO, there are two types of homeschoolers. There’s the students who are truly brilliant living in a part of the country that doesn’t value education, and they’re practically forced into homeschooling (or a popular online program like Stanford Online High School) in order to receive an actual education that could challenge them. They do get less socialization than their traditional schooled peers, but they’d get mercilessly bullied at a traditional school so it’s hard to say how much value that socialization has. The other type are the religious fundies. I have even more hands-on experience with this style, as some of my cousins were homeschooled in this manner. IMO, this shit should be illegal. It’s accepted because someone is typically monitoring these students’ academic progress, but I can say with confidence that Republican states are letting a lot of shit slide. It’s religious indoctrination at a level beyond what you would even find at a religious private school. Typically, these students are better socialized than the other homeschool students, though with the caveat that all their socialization happens in religious settings.
