Faire jour, are you aware of the Deaf charter school movement? There ARE quite a few Deaf charter schools opening up! Not to mention there's the question of whether or not the kids who would ordinarly go to State Deaf Schools are actually enrolled in formal Dhh programs or magnet schools. I'm not surprised that some State Deaf Schools are struggling.
But, a lot of that is political. It's the same reason why an inner city school would be struggling compared to a high class prep school. Not to mention , we are struggling with a very severe recession , and there are cuts ALL along the line for even wealthy school districts!
Oh, and you seem to be extrapolarating your experiance with your state's Deaf School, to all Deaf Schools. There are ones that are struggling with being underfunded and underutilized and are hanging on by a thread yes. But there is the Deaf Charter School movement, and there are some Deaf schools that are doing awesome, and are actually thriving. I also have to note that I've looked at most Deaf Schools' sites, and most of them (except for Beverly School for the Deaf) still have res programs.
