This paper is a study on the grade 8 students' vocabulary achievement using word games. The study was conducted at Kiwalan National High School and aimed to determine the effectiveness of word games as a learning method in improving students' vocabulary achievement. The data was collected through questionnaires and was analyzed through percentage, mean, t-test, and paired t-test. The results showed that there was no significant difference between the students' pretest scores in vocabulary when grouped to Word Games method and Traditional method with a p-value of 0.835, but there was a significant difference on the students' posttest scores in vocabulary when taught to Word Games method and Traditional method with a p-value of 0.0015. Additionally, paired t-test revealed that there was a significant difference between the students' pretest and posttest scores in vocabulary when exposed to Word Games method with a p-value of 0.00016, while the p-value of 0.257 achieved by the group of students taught to Traditional method was not statistically significant. Based on these findings, it is recommended that word games be implemented in vocabulary classes as an effective method for improving students' vocabulary achievement.
