A comparison of population and employment projections shows the gap between teacher supply and demand growing through 2025. Alternative certification programs (ACPs) were created to increase teacher production, but research on who selects ACPs versus traditional preparation programs (TPPs) shows mixed results as does research on new teacher attrition. Analyzing employment and preparation data for over 225,000 new teachers (56% ACP), we found male and teachers of color were more likely to be ACP prepared. Using survival analysis, we found TPP teachers were significantly more likely to remain in the classroom than ACP teachers. We also found that teachers of color were more likely to stay teaching after accounting for preparation differences, and Latinx teachers from traditional preparation programs were most likely to stay teaching.
