Mike Fortune-Wood wrote a book called "Can't Go, Won't Go" about school refusal, a subject with which he has been involved for some years. He claims there is no evidence to support the very widespread popular perception that young people who do not want to attend school will become recluses if they are taken out of school. He says that the opposite appears to be true. In the cases he studied, several children later returned to school; however, IIRC every single family said the experience of home education had been helpful to their child socially. I don't know whether your dd is (yet) actually distressed enough to be a school refuser, but you may nevertheless find the book to be a good read.
LastSummer, why do you feel that "suck it and see" is not an appropriate course of action? If a child is unhappy then surely it is worth trying something different which may represent a big improvement. It is possible she will not be isolated, or that she will be isolated but will not mind or will find it a price worth paying for being free of the things she disliked at school. Of course she might find she dislikes home ed even more than she dislikes school, but that could also be a valuable lesson and help her appreciate the positives of school more. What's the harm in trying it? The worst that will happen is that she won't like it and will go back to school after a while. Such an experiment is hardly going to destroy her life.
aries, I'm not sure what you mean about depriving a child of the normal teenage things. If you are referring to things like parties, gossiping, doing sports, playing in a band, putting on plays, watching films or going shopping with friends then I don't see why home education would prevent a young person from doing those things if she wants to. In fact I think my home educated 12yo probably does those things much more than the average child of her age, because of having far more time on her hands. Of course, not all young people want to do those things. Not everybody likes the same things. And if they don't want to do it, how is it a "deprivation" if they aren't doing it?
I was rather a loner at school. Going to school didn't make me more sociable or normal, it only made me more conscious of being different, and taught me that different was not OK. What made me more sociable and happy was leaving school at 16 and finding people whose interests I shared, who respected me for who I was. Interestingly, after I left school I found that some of the people I had known at school were much nicer people than I had realised. They had just found it very difficult to behave that way in the complex and sometimes claustrophobic social world of school.
