I found a federal grant put out by the Department of Education for gifted education that has, as a stipulation, services for underserved populations, including STUDENTS WITH DISABILITIES. I read that as twice exceptional students ;-)

Here is the link - I am having trouble loading it for some reason. The deadline has passed for this year, but we have plenty of time to gear up for next year's funding season!

One of the requirements is to include services to private schools, so that leaves out LAUSD or any other public school district as a sole applicant. However, I did think UC Irvine's gifted program could apply and the DAVIDSON INSTITUTE could certainly apply for twice exceptional services. :-D
