Hi ultra_nick,

>> trying to automate tutoring.

>> what's the best way to statistically guage a student's knowledge level?

As you have probably already discovered, there is quite a bit of research in this area :). If anyone else is interested, you can search Google Scholar for "deep knowledge tracing", "bayesian knowledge tracing", "performance factor analysis", "knowledge space theory", "intelligent tutoring systems", and "item response theory". Some intelligent tutoring systems include ALEKS, Squirrel Ai, and Riiid.
