[QUOTE="IEEEWreck, post: 881752, member: 617"] In short? Pretty well. I'm not the right person to pull out statistics, but the reason for them is both fairly basic and also illustrative of why it works. The short answer is the difference between accuracy and precision. That's a highschool STEM topic when the true value is trivial to identify if not measure. True values are moles per liter or newtons or amperes and there is no confusion around what is being measured or, in our world of extremely well tested models, how to calculate them. So that's great for the work done in a system, but things like mastery of educational material fundamentally aren't like that. How to define that is very much in contention and good definitions are almost always impossible to directly measure, so you have to substitute something you can measure as a stand in. You make your test as precise as possible, but the correlation between what you test for and what you're actually trying to measure aren't really knowable and in fact may not even be stable over time. The real world may not have extra time accommodations, but it also doesn't have a particular use for the ability to correctly calculate a useful frequency domain form of an equation or surface integral by yourself within a time limit and with severely limited tools. In fact, in industry a lot of engineers right out of school struggle to contribute in a team environment where which tools to select to solve a problem are far more significant than how quickly those tools are used. People whose minds have a different affinity and process for using tools, on the other hand, frequently contribute immediately because they bring a new perspective that can add to the total information awareness of team decision making. Often times, you might say, those folks that needed extra time to get through that physics test might just have used that extra time and effort that they understand that precision and accuracy are important and useful concepts, not just an answer to a test.
