APPRENTICE TOOLMAKERS AND MACHINISTS I r TJ 
opinion of this boy, after seeing his work for a month, was 
such as to raise his rank from tenth to fifth. If the indica 
tions given by the tests are reliable, this boy will rise still 
higher in the opinion of the foreman. There were several 
similar cases. In one, the foreman’s original rank was 
e 'ght, his subsequent rank four, and the rank in all the 
tests four. Another man was ranked by the foreman first 
as five, then as twelve, and by the tests as eleven. Still 
another was twelve, then eight, and six in the tests. The 
decided trend was to confirm the value of the ranks which 
had been obtained on the basis of the tests. The eleventh 
man according to the foreman was twelfth according to 
the tests; the first, first; the tenth, ninth; the second, 
third, etc. In brief, the testimony of the tests, given 
^mediately by a half hour’s examination, was a remark 
able forecast of what the opinion of the foreman-instructor 
^as to be after having known the men and trained them 
Pensively for a period of several weeks. 
No conclusive decision as to the value of these tests can 
h e based upon only twelve cases. However, it is almost 
^possible to obtain a large number of apprentices who 
have been trained under uniform conditions, for an equal 
^ en gth of time, by the same instructors. Preliminary to 
l he experiment under discussion we had given seven 
te sts to over two hundred apprentices in two of the largest 
Manufacturing companies in the country. However, the 
difficulties encountered in obtaining a uniform ranking of 
fach apprentice were so great that it was practically 
^possible to compute the significance of the tests. The 
lri tensive-training shop presented greater uniformity of 
c °nditions than had so far been met with. 
^ addition to the day shift there were two evening 
Masses. The pupils in these classes were tested and the
