Though it may not help us as adults, there are some protections for children who stutter in the US. Section 504 of the Rehabilitation Act of 1973, requires that all federally funded institutions make reasonable accommodations for people with disabilities. Almost all public schools in the country receive some kind of federal money so they qualify. Note that this does not apply to private schools, although I'm not sure if it could with a state that uses the "voucher" system for education. I personally used this when I was growing up, or I should say my parents made sure my school was aware of this. Because of it, I was never graded on class participation, and I was given alternatives to oral presentations. All this being said I went to a fairly liberal public school outside of NYC, so I did not experience much push back to this. I'm sure there are places where people would get a lot of pushback by invoking this. I completely agree that stuttering should be classified as a disability for adults as well, and should qualify a person for disability benefits.
