The way this fascinating and potentially creative problem is currently approached mathematically is to create not just universal STANDARDS for the content, but universal CONTENT. This makes it easy to show that the comparison formulas and norms work. For example, in this thread people said Python is two to five times more effective for them than Java. Well, the ancient test-norming math won't have any of that, and to the best of my knowledge, people have not done any concerted theoretical development in that area for the last fifty years at the very least. Why work on that complex task, when the same content for everybody can be mandated through test monopolies, trivializing the norming problem? Standardized tests as we know them aren't suited for any pluralism within one area, by their very design. Multisubculturalism has happened too recently to be taking seriously, I guess. At the other end of the spectrum, we have extremely open-ended interviews a-la, "Why are manholes round?" http://en.wikipedia.org/wiki/Manhole_cover#Circular_shape What we seem to want is something in-between. I hope my note shows some of the conceptual and administrative challenges involved in this, much-needed, change.
