There are many methods and forms of curriculums. Some all the parent has to do is oversee that their children are doing their work, but the instruction comes from some other teacher (video, online, correspondence). Also, who is a child's first teacher? A parent is more qualified than you think. There are many teachers who know very little and all they do is open up the curriculum book and dictate from that (same as some, not all, homeschooling parents). Those that abuse homeschooling are actually in the minority. Or you may be THINKING that they aren't really schooling if their schedule isn't the same. If you see them at the store during the day they could be either done early, schooling on a four day schedule, a 2wk on 1wk off, or school in the evening. We used to school our oldest in the evening after our younger children went to bed. Dh worked 2nd shift and so the morning was spent with dad, at the park, running errands, etc. I know other 2nd shift families that do this.
Also, where does negligence equate cultishness?
