This study investigates the impacts of junior high school student's test anxiety on mathematics academic achievement, and academic resilience as a moderator. The participants were 830 seventh graders. The analysis method includes descriptive statistics, t test, and hierarchical regression analysis. The major results were as follows: (1) Junior high school seventh graders' math test anxiety is moderate; (2) The gender has a significant influence on efficacy of math academic resilience that the male is more significant than female; however, no significant influence from gender was found on emotion and interpersonal relationship of math academic resilience; (3) The students' math test anxiety has a significantly negative association with math academic achievement; (4) The students' math academic resilience moderates effects on the relationship between math test anxiety and mathematics academic achievement. Finally, discussions and suggestions for instructional implementation and future study were proposed.
