The experiment was designed to test the validity of the three device evaluation procedures which had been constructed and revised on the basis of field trials. The experiment involved several purposes 1 To establish the criterion scores reflecting the over-all training effectiveness of a number of training devices, as bases or standards by which the evaluation procedures could be judged or validated. 2 To measure the effectiveness of the three evaluation procedures, each as a whole and item by item. 3 To furnish a valid basis for the revision of the three experimental procedures. The criterion consisted of independent estimates of the over-all merit of each device for its training purposes. These were in terms of comparative ratings of instructors and training officers who were well acquainted with the devices rated. Author
