Directions for Scoring the Test.
The score in this test is the total number of pairs the identity of which has been correctly checked, minus the total number of pairs in which an error has been made in checking the identity. For example, if the last line checked was the twenty-fifth line while two lines had been omitted and errors had been made in checking three other lines, then only twenty lines had been checked correctly, and three lines had been checked incorrectly; so the resulting score would be seventeen points. The maximum score obtainable is of course thirty points and will be obtained only in case every pair has been checked without error. It is possible with this method of scoring to obtain a score less than zero; for example, if a person had checked correctly ten of the identities and had made errors in checking fifteen others, the number of “rights” minus the number of “wrongs” would be minus five. In such cases the score to be entered on the lower right-hand corner of the candidate’s title page is zero.
The stencil furnished with the test leaflets makes it possible to mark this test with great rapidity and without mental fatigue. The point at which care needs to be taken is in making certain that the total score, computed by subtracting the number wrong from the number right, is correct. For this reason the reader is advised to cross out the “line number” of any pair incorrectly checked and to draw a circle around the “line number” of any pair not attempted by the candidate. If this is done consecutively down the page, there will be little difficulty in calculating the total score.
Scores from 0 to 8 indicate Inferior Ability
Scores from 9 to 12 indicate Low Average Ability
Scores from 13 to 22 indicate Average Ability
Scores from 23 to 26 indicate High Average Ability
Scores from 27 to 30 indicate Superior Ability
