Okay, I have a meeting with DS's GT teacher this afternoon. My DH and I are going in with the results and a bit of information. What if the GT specialist looks at the results and says they don't indicate anything different be done with his curriculum?
I for sure would see this as a first step on a long road of advocacy, and be prepared that the Explore results may not be impressive to them (even when they should be!). The principal and gifted teachers at my daughter's school, a school with a huge % of students with gifted ID, did not even seem to be familiar with Explore at all. We decided to ask for a grade skip, and they used the Iowa Acceleration Scale and did their own achievement testing.
I would think about what you want to get out of the mtg. Like, specific ideas for subject acceleration, if that is what you want, cluster grouping for next year, etc. Do you have WISC results? You may need those to get more results. So, I don't really have experience with getting better in-class differentiation, only with asking for and getting a full skip that went smoothly because the district has a policy in place. Good luck!
