The main purpose of this study is to explore the relationship among family economy, life-style and school performance of ECEC(early childhood education and care) department student. A questionnaire is conducted with 978 ECEC department students for collecting data. The obtained data is analyzed by confirmatory factor analysis (CFA), analysis of variance (ANOVA), and structural equation modeling (SEM). The result of CFA shows that there are three life style factors among ECEC students, including romance and caring style, self-decided and ambition style, social and fashion style. Based on ANOVA, it is found that high economic status students tend to be self-decided and ambition style, while low economic status students tend to be social and fashion style. However, structural equation modeling analysis shows that ECEC students' school performance is significantly influenced by their life-styles.
