Concerto, IRT and CAT

Concerto, Item Response Theory and Computer Adaptive Testing

We run a series of three-day events. These workshop will enable you to produce your own state-of-the-art psychometric tests online, as well as introducing you to the power of Item Response Theory (IRT) Computer Adaptive Testing (CAT) and the open source online adaptive test development platform, Concerto. We will teach you the necessary methods and show you how to develop an online adaptive test. The schedule is flexible and can be adjusted to your requirements and to the progress of participants.

Note: Workshop participants should be equipped with computers that can run Google Chrome Internet browser. Internet connection is desirable but not necessary.
