Oh, as you would imagine, there are lots of reasons. And these students are, I think, as a group, a group of students who are taking a state's alternate assessment, which is designed, as you said, for about that 1% of students who have the most significant cognitive disabilities. And I think the percentage is somewhere around 16% of students with the label of intellectual disability, spend 80% or more of their time in general education. And that's kind of an average across all the states in the United States. Some states do better Vermont, Iowa, Alabama, but some states do much worse. And, I mean, some of the reasons that that I've been thinking about, and these are in no particular order, but the first one is really prejudice. And prejudice defined as kind of a preconceived opinion about a group of people that's really not based on reason, or actual experience. And just a couple of examples about how that that plays out in schools, I don't know if you ever heard someone say, Well, this child with Down syndrome really should be with others of her same kind. As if there's a, you know, some broad definition of people with Down syndrome than every single person, it's yours, too. And that's really a kind of prejudice, it's like, you know, you've had maybe one experience with a child or an adult with a disability, and then you generalize that experience to all people in who happened to have that same, that same attribute. And I mean, you know, it's, it's similar to racial prejudice, you know, you meet one person of Asian descent, who is really good at math. And therefore, you say, oh, all these students of Asian descent are really good at math, I mean, that's kind of one side of the coin has kind of a positive prejudice, but it can also really be negative, or you meet one person with a disability who has really difficult time reading, and therefore you assume all people with a label of whatever, are going to have difficulty. And I think, maybe even a little bit more underlying that prejudice, is looking at people with disabilities as less than lesser humanity, and people with without disabilities. And so those kinds of prejudices, really get infiltrated into our educational system into our decisions about placement, or decisions about how we envision the future for for the children that we have now. And certainly, you can jump in with any any comments that you have about that.
