K-12 schools in the United States are suffering from an epidemic of teacher attrition: nearly half of all new teachers leave the field within their first five years, and thousands of teaching positions across the country are going unfilled. What can school leaders do about this persistent turnover and the resulting loss of human potential?

In this timely book, Bryan Harris describes the four broad supports that he says are crucial to helping early-career teachers succeed and stay in the profession: comprehensive induction programs, supportive administrators, skilled mentors, and helpful colleagues. He offers practical, research-based strategies to help leaders provide these supports and create a culture of collaboration across the school. The result is a school in which beginning teachers truly thrive as effective practitioners who see themselves successfully helping students learn more every day.
