Key: This shows the mark for each number
Make under each number the mark which should be there
The individual to be tested should be shown the page on which he is to work, for not more than twenty seconds, and should then be shown the two examples appearing on the title page under the printed instructions, “Make under each number the mark which should be there.” The examiner should then compare his key and the digits appearing in the sample series and should write in the proper spaces the appropriate symbols. The idea of getting the symbol from a key will be emphasized and made clear if the examiner at each point moves his finger or pencil from the digit in the example to the digit in the key, then to the symbol in the key and back to the empty space beneath the digit in the example. When all the spaces of the example have been filled (this should be done very slowly at first and then more rapidly toward the end of the example), the examiner should open the booklet, supply a pencil, and say, “Now! Go ahead! Put them in! Hurry up!”
Exactly two and one half minutes (150 seconds) should be allowed from the time the examiner says, “Go ahead,” to the time he calls, “Stop!” All papers should be closed immediately and handed to the examiner.
Directions for Scoring the Test.
The score in this test is the number of symbols correctly supplied. Marking the errors is very much simplified by the use of the stencils furnished with each package of test booklets. The number of symbols correctly written should be recorded at the end of each line in the test and the total for all lines should be entered in the lower right-hand corner of the title page of the booklet.
Scores from 0 to 20 indicate Inferior Ability
