School districts may not seem interested in helping students. This can be for many reasons. When I suggested an independent study option to the principal of my son’s middle school because my son is a figure skater, she told me that the law did not allow it. When I actually showed her the law, I had it printed out, she was shocked because she was told year after year by the district that independent study was not allowed. Once she read the law she stood up and walked over to her computer, with me in the room, and shot off an email showing her support. I was one step closer to getting what I needed. I just kept on plugging away until I had support and got a final OK, which came from the assist superintendent, and was solicited by a councillor at my son’s school who wanted to see it work. Why did she help? Her son was a hockey player. Our children had something in common and she found value in our ideas.
If the OP can find someone at school who agrees with her ideas for social justice and finds value in her project she might be able to pull it off without having to leave and with support.
@ayyyyy - Don’t know if you are still reading all this but what I have learned this past semester, as I pull my son out of school for homeschooling, is that there are a lot of options. Ideas that I never even considered suddenly presented themselves. People who I never thought would be supportive voiced their support. Look around for options. You might be surprized. BUt like @isaelijohjac stated, time is of the essence.
