It was conducted by using experimental research design. The Population of this research was the tenth (X) grade students of SMAN 1 Tanjung Balai Asahan which consists of 4 parallel classes with the total number of students is 128. The samples of this research were taken by random sampling through lottery technique.

The experimental group was taught by using Think Talk Write (TTW) Strategy while the control group was taught by using Conventional Strategy. The instrument for collecting the data was writing test. The data were analyzed by using t-test formula. The result shows that the value of t¬-observed (4.362) is higher than the value of t-table (2.000) (α = 0.05) with the degree of freedom (df) = 58. It means that there is a significant effect of applying Think Talk Write Strategy on students’ writing achievement in descriptive text. So, the alternative hypothesis (Ha) is accepted.
