The instrument for collecting the data was a writing test. Pearson Product Moment formula was applied to obtain the reliability of the test. Based on the calculation, it shows that the reliability of the test was 0.86 categorized as high reliability. Then, after analyzing the data, it was found that the value of tobserved was 5.57 with the degree of freedom (df)=70 at the level of significance (α = 0.05).
