This study aimed to assess the completeness of learning outcomes related to the effectiveness of the Scavenger Hunt Game method in enhancing students' vocabulary mastery at SDN 4 Muara Beliti. A pre-experimental approach was employed, utilising a one-group pre-test and post-test design, with a sample of 20 fourth-grade students. The sampling technique adopted was purposive sampling. The analysis technique uses a normality test, while the hypothesis uses a Paired sample t-test. The pre-test showed an average score of 41.50 with a standard deviation of 17.021, where only 2 of the students reached the "Mastered" level. After four sessions of treatment using the Scavenger Hunt Game. The post-test average increased to 74.75 with a standard deviation of 10,818, and 12 students achieved the "Mastered" qualification. The results of these tests showed that the paired sample test result showed that the significant value is lower than substantial (0.001 < 0.05). It means that Ha which stated that there is considerable difference scores of students’ vocabulary mastery before and after taught by using scavenger hunt game for the fourth graders at SDN 4 Muara Beliti was accepted Whereas, H0 which stated that there is no significant difference scores of students’ vocabulary mastery before and after taught by using scavenger hunt game for the fourth graders at SDN 4 Muara Beliti was rejected.
