The purpose of this research was to investigate the reliability and validity of 6th grade English sub-test of the Level Determination Examination (SBS-2009). The psychometric characteristics of the test were tried to be determined for this purpose in the study. In order to determine the construct validity of the test, the exploratory and confirmatory factor analyses were conducted. KR20 and Spearman-Brown split half statistical methods were employed in order to determine the reliability of the test. According to the findings in relation with the exploratory factor analysis, it was seen that 13 items in the English sub-test worked under a single factor. Besides this, in order to confirm the structure which was detected in regard of the exploratory factor analysis the confirmatory factor analysis was conducted in the research. The findings in relation with the confirmatory factor analysis [X2/df=109.73/65; GFI= 0.92; AGFI= 0.89; RMSEA= 0.058; CFI= 0.96; NFI= 0.90; NNFI= 0.95; RMR and SRMR= 0.052] approved the structure consisting of a single factor. On the other hand, KR20 reliability coefficient of the test was found as 0.84 and Spearman-Brown split-half coefficient was found as 0.81 in the research.
