Each exercise was marked either right or wrong, and the sum of the rights for each individual was obtained. This was then expressed as a completion test mental age based upon the me- dian accomplishments of some 700 public school children of dif- approximately equal number of boys and girls. As the girls did year should be deducted from the norms when comparison is made with the records of boys only. The scoring of all the papers was under the supervision of the writer, and the same possible. The procedure of standardization is not here given, as the more complete work of Trabue (130), now in print, makes the test per se unimportant.’ As a number of the scores were as mental ages, the median is used as the group measure. The Binet test, Constructive Ability Test, and Completion Test scores have each been expressed in terms of a mental age Occasionally more or less arbitrary assignments of mental ages had to be resorted to in averaging some of the very poor and very good records that were made upon these three tests. These are explained in detail in the succeeding section dealing with norms for the various tests.
