This "Lessons Learned" report finds two specific areas in which teacher training may be lacking: preparedness for the diversity of the contemporary American classroom and teaching students with special needs. Seventy-six percent of new teachers said teaching an ethnically diverse student body was covered in their training, but only 39 percent said that training helps them in the classroom. The survey covered twelve areas of teacher training ranging from direct instruction to their study of history, philosophy, and policy debates in public education. An Afterword by Sabrina Laine suggests that finding answers to several questions raised in this report is paramount for the systems that prepare and support teachers to adapt the realities of the 21st-century classroom.
