Twenty words were selected at random from column Q of the Ayres Spelling Scale. These words were given as a dictated spelling test to 29 pupils in the 5th grade of the I. S. T. C. Training School. The papers were scored and it was also determined how many times each word was missed. The ten easiest words were then considered as one test and the ten most difficult words as a second test.
