Current Research

The tests on this web site are part of an on-going program to automate all phases of testing, including item development, calibration, norming and validity. Specifically, this program includes 1) generating items automatically to fulfill cognitive design principles, 2) establishing construct validity at the item level, with calibrations of the level and sources of cognitive complexity, 3) estimating item psychometric properties from cognitive design principles, 4) linking scores to processes involved in item solving, 5) improving norms continuously by incorporating new data, 6) checking the item generation calibration of cognitive design principles for impact on item psychometric properties, prediction of item properties and the source of cognitive complexity the level and source of predicted.
