OP here.

Yes, sorry, I should have mentioned that DS has had an IEP since Kindergarten, which provides speech therapy and in-class accommodations for inattention and organization issues.

I spoke some years ago with Marisa Stemple during a GT/LD presentation, She was kind but non-committal and told me the decision was up to the IEP team, and her role, if called in, would be to inform the team. ?

Have you spoken to Marisa Stemple?

Maybe worth a call:

Does your child have an IEP at his present school?

My 3rd grade son was just rejected for entrance to a Highly Gifted Center in MoCo.
His test scores were all slightly below the median of accepted students, and he has ADHD and Asperger's, so we were on the fence anyway about sending him to such a classroom.
His grades are mostly Ps.

While his learning disabilities are well taken care of at his homeschool, he is not interested in any grade-level subject, complains of being bored and reads things like Jurassic Park, loves science and history of warfare (talks about genetics, WWII, etc).

For parents who considered the GT/LD program or who have children there, do you think he would be a good fit? Would there be leeway in that class for special-interest projects? What are the criteria for acceptance?

Thanks for your help!
