You know, I saw when this website was posted earlier.<p>I think it's awesome you provide both faxing and scanning interfaces.<p>I had two questions:
1. Where are you based? Why don't you have a snail mail address on your website? It's not even clear you are based in the U.S.<p>2. On a more stat based note: When you analyze the data, are you merely analyzing the students, or are you providing IRT analysis for the test questions themselves? Do you provide support for A/B testing of test types, or dynamic testing in your online interface?<p>Because to me, those are things your average teacher can't do, but knowing how well each question and each test assesses students modeled as a function of student ability means that your assessments aren't just easier, but can be made better at measuring ability.<p><a href="http://en.wikipedia.org/wiki/Item_response_theory" rel="nofollow">http://en.wikipedia.org/wiki/Item_response_theory</a>
