Kot

Kot is a basic toolkit for getting started with computerised adaptive testing (CAT) in Ruby.

It includes:

a module to calculate item response theory (IRT) statistics for dichotomous items with 1-4PL characteristic curves (ICCs),
a Hill Climbing ability (theta) estimator,
a Randomesque selector and
a Test class to make tying all this together easier.

Thanks to

douglasrizzo's catsim and its excellent documentation, without which I wouldn't have been able to cobble this together.
