A scale of Test Anxiety based on the aspects by Cassady and Johnson (2002) was used to measure anxiety levels with a reliability value of 0.944. The analytical method used is the Friedman and Kruskal-Wallis test. This study found that aromatherapy was effective in reducing calculations in the test using the Kruskal-Wallis test with the Asymp value.Sig p <0.05, the test scores for participants between group KK, KE1, and KE2 based on the pre-test results with p = 0.450 , post-test 1 with p = 0.025, post-test 2 with p = 0.019, and post-test 3 with p = 0.011. Aromatherapy can be used to reduce test anxiety as an effective independent therapy.
