Since the 1960s, concerns for beginning teachers have attracted extensive attention. High attrition rates among beginning teachers have been an international challenge, which is costly for a nation's budget. To improve the retention of new teachers, it is imperative to understand what beginning teachers have experienced in their professional practice. This qualitative research examined the career development trajectories of beginning kindergarten teachers in China. The experiences of 23 kindergarten teachers from Nanjing were investigated through semi-structured interviews. Using grounded theory, this research identified four main themes and four career development trajectories. Themes include orientation, mastery, re-examination and self-validation, while career development trajectories reveal that teacher career development is not unilinear, but diverse. These findings are crucial in raising the awareness of researchers and practitioners about the diversities and possibilities of teacher career development trajectories. Further implications for researchers, teacher educators and kindergarten teachers are discussed.
