They refuse to even consider anything that doesn't have an accredited stamp on it.
I ran I into a similar mindset problem when DS13 had skipped third grade. He wanted to do fifth grade science, and it wasn't allowed because the person running the school had decided that you couldn't possibly understand fifth grade science unless you had done everything in fourth grade science. The books all basically told the same story, but each grade level gave more detail and used more technical words. He just wanted to learn more details, but it was too bad.
Unfortunately, our education system in general just don't get it on many levels.
Some have said this lock-step, one-size-fits-all approach is their primary concern with Common Core. A rigid, inflexible approach to placement and pacing lacks respect and sensitivity for intellectual diversity.
