TEST ADMINISTRATION 
Preliminary details in test administration. The examiner's attitude. The 
testing room. Procedure in testing. 
NEw tests must themselves be tested. To evaluate the 
examinations he has devised, the investigator uses them to 
obtain scores made by workers of different known levels of 
vocational accomplishment. He then examines the results 
to determine which instruments most successfully differen- 
tiate one level of accomplishment from another. This chap- 
ter treats of the measuring of these selected workers as a 
step toward the validation of the examinations. 
The administration of rating scales and questionnaires 
has already been discussed in part in the chapters which 
deal with their development. Tests require far more care 
in their administration. The conditions need not be as 
rigidly standardized as those of a laboratory experiment, 
but tact and courtesy are more essential than in the labora- 
tory. 
The investigator should ordinarily leave to the executive 
most immediately concerned with the success of the in- 
vestigation the matter of arranging the time of testing and 
insuring the presence of the employees. If he is testing for 
ability in some minor occupation, he should arrange with 
the foreman or supervisor the details of time of testing, and 
this executive will notify the men when to appear. 
The investigator would do well to think how he himself 
would feel in the man’s place. He would be wondering 
what this was all about and how it was going to benefit him. 
Will a low performance in the test count against him with 
his supervisor? Will a high score be used to make him
