The federal School and Staffing Survey (SASS) and Teacher Follow-up Survey (TFS) were used to examine the impacts of induction activities on beginning teacher turnover. This study excluded those teachers who moved or left schools for unavoidable and involuntary reasons, a confounding factor in previous research. This analysis revealed that three induction activities are beneficial in significantly reducing turnover rates for beginning teachers: seminars, common planning time, and extra classroom assistance.
