It is also known as diagramming, webbing, looping or mapping. Therefore, the research aims at finding out empirical evidence concerning whether clustering technique is effective or not for students to write a recount text. The method used in this research was quantitative, and the research design was a quasi-experiment. The sample of this research was the tenth grade students of SMK Mahadika 1 Ciracas Jakarta. The experimental class is from X AP 1, and the control class is from and X AP 3 with 30 students from each class. Based on data analysis, the range score from experimental class is 57-86, while from control class is 50-84. Furthermore, the research findings shows that t<sub>count</sub> = 3.098 and t<sub>table</sub>= 2,002 with the significance degree of ? = 0,05 (t<sub>count </sub>> t<sub>table</sub>)<sub>. </sub>Sincet<sub>count </sub>is higher than t<sub>table</sub>, it means that H<sub>1 </sub>is accepted. It can be concluded that there is a significant effect of using clustering technique towards students’ writing skill in recount text.</p><p>Keywords: Clustering Technique, Writing Skill, Recount Text</p>
