A Study on the Effect of Rater’s Language Background in Korean Writing Test: Centered on Raters’ Familiarity with L2 Learner’s Native Language

The study explored the influence of raters’ language background on their rating. The raters in the research were divided into 4 groups: Chinese Han group (CC), China Korean group (CK), Korean raters who are familiar with Chinese (KC) and who are not (KK). First, by Multi-facet Rasch Measurement, the result showed that raters show greater difference in severity when rating organization compared with grammar. Then, the comparison of ratings within groups was made. The results were as follows. In rating grammatical items, no significant difference among groups was found. However the interview after the research showed that some raters were actually influenced by their language background. In rating organization part, different results appeared. When examining all the items, there was no difference. But when the item “the overall organization” was examined, there was significant difference between Chinese raters (CC+CK) and Korean raters (KK+KC). And the difference exited between CC and KK as well. It can be seen that raters’ L1 does bring influence on the item rating. Besides, the ratings between KK and KC were compared. The results showed no significant difference. Further improved by the subjective statements and interview, it can be seen that for Korean raters their native language still plays a decisive role in rating.
