I have one introvert and one extrovert. Both made friends at Montessori school. There was way more time for socializing there because there weren't many teacher lead activities and not very many transitions. My girls transferred great to public school. My dd9 has made many friends but none close. I believe this is due to her giftedness. I think that if it is adult interaction you are looking for for your child and not adult guidance then Montessori would be a bad choice. But I can't think of a school environment that provides a lot of adult interaction other than some special education programs.
