In this study, the authors examined the direct effects of preservice preparation quality and early career support as well as potential moderating effects of early career support on the career intentions and decisions of novice teachers. The findings confirm and extend prior research related to the effects of early career support alone and in conjunction with varying levels of satisfaction with preservice preparation. The authors show a direct association between new teachers’ perceptions of preservice preparation quality and their intentions to remain in their current school and in the profession. In conclusion, this study provides a first and important step in filling a gap in the teacher attrition literature by examining whether mentoring and induction support differentially influences beginning teachers’ career intentions and decisions depending on their level of preservice preparation.
