I'm completely new to the idea of co-ops. I'm wondering if it's standard for parent-led co-ops to be organized into grade level classes? There are so many co-ops in my area and I'm wondering if I can expect this type of organization. I have a child who does not fit into a grade level across the board, so, on the surface, it seems problematic. What do you do if you think your child belongs in a higher grade level class? Would that, typically, be a difficult thing to negotiate? Again, I'm really new to co-ops. I'm just researching options in my area. I was surprised at how "school-like" the co-ops seem to be, at least on the surface.
