OBERD CAT

OBERD’s methods, based on machine learning with predictive modeling, differ from those employed by the MCAT test or most other adaptive systems in their ability to produce CAT versions of existing forms. OBERD’s CAT measures produce scores that are fully interchangeable with standard instruments used today, with a 40%-60% saving in patient effort.
