I used to be a troubled teen as well. In Jr. High, I could not concentrate, got poor grades, wasn't too motivated to get good grades. My parents were so wrapped up in their own lives that they didn't work with me in any classes. It took many years for me to care about education on my own. However, I also had a grandmother that bought me everything and I really didn't have any reason to worry about anything else because she did so much for me. I guess what I am trying to say is with your daughter, it might be best for her to face the consequences of her actions and maybe repeat the grade. I think that if my parents had held me accountable for my actions (not caring about school, hanging out with the wrong people, and so on) I would have developed good habits of accountability. If you pull her out of school and home school her, she might think that you will always rescue her and therefore not try as hard. If she has struggled with grades, but puts for a great effort, then that is a different story. I am just speaking from my experience and now being 34 with a child of my own, I see how important it is to make your child responsible for all their actions so that they develop positive independence. It might seem trite now, but if she continues her attendance behavior, among other things, she won't be able to hold down a job in the future because she has developed poor habits (this one being attendance) that will follow her for the rest of her life. You seem like a very concerned, loving parent and I know that you probably tried everything. If you are truly at your wits end, I would highly recommend seeing a family therapist. Good Luck.
