There is an urgent need not only to attract more people into the teaching profession but also to build a more diverse, highly qualified, and culturally sensitive teaching force that can meet the needs of a rapidly changing school-age population. This Toolkit takes best practices from high school teacher academies around the United States and organizes them into the steps needed to design and implement programs. The purpose of the Toolkit is to help school districts plan and institutionalize high school teaching academies in order to nurture and "grow" prospective teachers committed to serving their schools and communities. Research done by the Urban Teacher Academy Project suggests that there are approximately 50 teacher academy programs in the country. These high school teacher academies are teaching-focused, comprehensive academic programs within larger schools, most of which offer electives related to teaching, learning, and children, with precollege internships in schools and partnerships with colleges and universities that provide a pathway into college and teacher education. The guide's first chapter gives strategies for putting the elements of a successful teaching career academy into place. The second chapter explains the important elements of effective programs and gives a look at how these elements have been implemented in other teaching academies. The third chapter provides advice on how to document and assess a program. An appendix provides useful information about other national precollegiate teacher recruitment programs to supplement or support teaching career academy activities. A planner's checklist is included to outline steps in designing a teaching career academy. An appendix contains descriptions of three teaching career academy programs, and a list of useful resources for establishing a teaching career academy is included. (SLD)
