Just flipped back through the thread and was reminded that you homeschool...that gives a slightly different flavor to your advocacy. What is your objective in the IEP meeting? Are you seeking appropriate (GT or disabilities) services for your DC as a fully-enrolled public school student? Ancillary services as an in-district homeschool student? Instructional guidance for you as the homeschool parent and primary direct provider of instruction? The advocacy approaches of most utility will depend on your purpose.
