<p style="text-align: justify;">The introduction of English language teaching (ELT) at the preschool level has been widely discussed by researchers. While most agree with ELT at preschool level, considerable issues are faced in learning a second, third, or foreign language. Therefore, this systematic review discusses the issues preschool teachers face in implementing ELT and their beliefs on how ELT should be applied to young children. Using three renowned databases, namely Scopus, Web of Science (WoS), and Educational Resources Information Centre (ERIC), 34 articles were extracted out of 85 articles, from 2012 to 2022, with exclusion and inclusion criteria taken into consideration. The findings of this study showcased eight main issues faced by preschool teachers in implementing ELT: English language proficiency, pedagogical skills, teacher perception, curriculum, teaching resources, training, socio-cultural, and classroom environment. In terms of preschool teachers' beliefs about ELT, there are four main issues: Bilingual education, children's characteristics, curriculum alteration, and teachers’ experience. Generally, these findings will guide teachers, responsible authorities, and researchers to acquire an overview of the actual issues that occur in the implementation of ELT in preschools as well as the appropriate measures to overcome them, starting from the preschool teachers' beliefs.</p>
