The third group had met only twelve times, which meant only three days of actual work. Consequently, although the correlations between the opinion of the instructors and the rank of the pupils in the tests are already significant, their true significance cannot be stated until more time has elapsed. It may or may not be significant that the trend of the correlations varies directly with the length of time which has expired. In order to obtain a true estimate of the ability of a group of apprentices and trained workers, it is necessary to give to the entire group a thoroughgoing practical examination in the work which they are supposed to have learned. Very few apprentice schools make a practice of this precaution. They assume that when a boy has passed through their various grades and classes of work, he is qualified to serve as a full-fledged journeyman. This assumption is patently unjustified.
