Section 2. — Directions for scoring examination a. 



[Sent out as supplement to the Examiner's Guide first revision.) 

 Test 1. 



Item, 3. — The line may begin or end either on the circumference or within the circle and may just touch either of 

 the inner circles but should not cut through either one. 



Item 4. — In this and item 5 the figures or cross should not be made to extend across any black line unless slightly 

 as though by accident. 



Item 6. — Here the proper numbers may be crossed out in any manner, but underlining is counted wrong. 



Item 8. — In the circle marked "not 12" (on stencil) there may be any number which is not 12, such as 5, 0, 27. 



Item 10. — -Underlining in place of crossing out counts wrong and vice versa. 



Test 2. 



If all the digits in any set are given and in the right order, the set may count as right, even though written in the 

 wrong line of squares. No set is correct unless the digits are all given and in the right order. 



Scorers should take notice when the same error occurs throughout the blanks of a given group and consider the 

 possibility of an error having been made by the examiner in giving the test. 



Test 3. 



If in each item the proper word "true'' or "false" is clearly indicated in any manner, such as by a check, the 

 item may count as right. If only the word " true" is underlined all the way down the page, or similarly only the word 

 "false," a score of zero may be given immediately with no further notice. 



'Test 4. • 



Items 9 and 13 may count as right, even though the decimal point is left out, providing, of course, the figures are 

 right. The fraction in item 15 may be expressed either as a decimal or as a common fraction. 



Test S. 



If in any item the proper word is clearly indicated in any manner, such as by check or by crossing out the other 

 three, the item may count as right. However, if two or more of the last four words in each line are underlined or other- 

 wise indicated, the item shall count as wrong. Underlining words other than the last four may be overlooked. 



Test 6. 



If in each item the proper word "same" or "opposite" is clearly indicated, as by a check, the item may count as 

 right. If only the word "same" is underlined all the way down the page, or similarly only the word "opposite," a 

 score of zero should be given immediately. 



Test 7. 



If in any item the proper answer is clearly indicated in any manner, as by a check in the square or by underlining, 

 the item may count as right. If, however, in any item two or more answers are indicated, the item shall count as 

 wrong. 



Test S. 



Here the proper number should be put in each blank place.
