It took a bit of work to convince them how advanced my daughter is, but once they were, it wasn't hard to get them to agree (at least in theory) to use enrichment materials from a couple of grade levels ahead, and also to progress with core skills.
I can't remember exactly how I worded it, but I emphasised that enrichment was excellent, but the opportunities for enrichment widened so dramatically over those first few grades, and she was so far beyond the grade level work that the enrichment around her grade level didn't count as enrichment. So she's getting enrichment that is normally given to the kids a couple of year levels up, and some core skills (not at the right level at the moment, we're still negotiating testing).
