Mathematics is a fundamental subject to science, technology and engineering. Therefore, a good mathematics achievement is required for students to face the future challenges. However, the problem of low mathematics achievement still persists and one of the factors have been found to contribute to this problem that include teacher factors. Previous researchers have linked teacher factors with various elements such as teacher quality, teacher effectiveness, teaching practices, teacher characteristics, Teacher Pedagogical Content Knowledge (TPCK), teacher satisfaction and professional development. However, knowledge of the dominating teacher factors has been very limited in recent five years of research especially in mathematics achievement. Therefore, a systematic review will be conducted to identify the issue. The articles used in this review were accessed from January 2019 to June 2019 using the Scopus database and Clarivate Analytic Journal for Web of Science (WOS). To ensure that this review was done systematically, guidelines by Preferred Reporting Items for Systematic review and Meta-Analyzes (PRISMA) were used. It is found that the dominant of teacher factors that significant relation with student's mathematics achievement is teacher characteristics from dimension of teacher quality. Therefore, the stakeholder needs to emphasize on the teacher characteristics dimension of teacher quality to improve student's mathematics achievement.
