This research aims to examine the validity of originality scoring guide of TTCT figure A, the most
widely used creativity test in the world, in order to evaluate the credibility of its usage to Korean
elementary schoolers without a standardization process. With the subjects of 1,042 1st to 6th graders
from 4 elementary schools around the capital area, TTCT figure A test section 2 was tested, and using
the same method used to make the original TTCT grading manual, a korean-version originality grading
manual was made. Results of two manuals were compared and analyzed. The summary of the research
result is as follows. First, statistically significant differences were reported between the originality test
scores of the two test manuals, the original one and the Korean version. American grading manual
produced higher score but lower standard deviation, suggesting the original manual relatively lacks
distinction ability. Second, conformity score of the original version, based on the Korean students' response
rate, was only 37 out of 113. The result shows what happens when a guideline created in a different era
and a place is adopted to another era and a place without consideration of cultural differences. It can
lead to compromization, even distortion of the data. The test result advocates the need to re-standardize
the orginality scoring guide of TTCT up-to-date so it properly reflects the present Korean society.
