This book explores the experiences of men and women who train to teach ESL as a second career. Drawing from in-depth interviews and observations of 30 students (aged 45 to 73) in a TESOL graduate program, this book provides portraits of these individuals as they develop as teachers. It describes the processes they go through to launch their teaching careers, the successes and challenges they face, and the evolving significance of their work in their overall life goals and achievements. A welcome addition to the growing literature on teacher development, this book will be an important resource for teacher trainers and anyone working in TESOL.
