Hi Autumn! I'm new to all of this too. You might have to explain to me what an IEHP meeting is? I'm assuming that it is an Individualized Educational Plan of some kind, but the "H" has me guessing?
My state mandates that gifted kids have WEPs (written educational plans), and so everyone here has slightly different experiences. Does this mean that you have some testing results from your son? Do you know what they will offer for your son at this IEHP meeting? Do you know what
you want them to offer at this meeting?
I found this link on Hoagies Gifted web site. It discusses IEPs and points out some important information on IEP meetings. I don't know if it is too general for you, or if you have any specific questions?
