and self-structured questioner, and statistically a descriptive and inferential
statistical analyses was used, the relative variation,Pearson's correlation test, and
"ICC" i.e. Interclass Correlation Coefficient respectively…i.e. quantitative,
descriptive correlation study, Result: the inferential statistical analyses yielded a“coefficient of variation”

value for R1U and R2U and for R1S and R2S as (28.455,34.930) and (10.870, 16.028) respectively. Cronbach's alpha reliability was found
(0.455) for R1U and R2U raters and (0.951) and was (0.463)R1U and R2U, and for R1S and R2S was significant (P0.001) with value of (0.951 which rated excellent).
Bivariate correlation was significant and with value of (0.906test for Structured oral
exam, and was not significant with value of (0.054) for unstructured oral.
Conclusion: We concluded that the Structured oral exams is more reliable than unstructuredoral exam.
