I don't think dreamchaser meant ill will with the title. But a better title probably would've been: "Are some of the classes in separated public school classes with deaf students not of the same standards as hearing students" or something to that effect.
But to answer the question, I never felt that my education was lacking when I was in my IEP classes - it was no different than a study hall hour and I probably accomplished more. Other than my IEP classes I was in regular classes with all hearing peers.
