"The MetLife Survey of the American Teacher: Collaborating for Student Success (2009)" was conducted by Harris Interactive and is twenty-sixth in a series sponsored by MetLife since 1984 to give voice to those closest to the classroom. This "MetLife Survey" examines the views of teachers, principals and students about respective roles and responsibilities, current practice and priorities for the future. The "Survey" findings were originally released in three parts: Part 1: "Effective Teaching and Leadership" examines views about responsibility and accountability; what collaboration looks like in schools, and if and to what degree it is currently practiced; Part 2: "Student Achievement" examines views on student goals, teacher expectations, and what educators believe would increase student achievement; and Part 3: "Teaching as a Career" examines collaboration in the context of teacher professional growth, experience level and career path. A national sample of public school students in grades 3 through 12, public school teachers of grades K through 12, and public school principals in grades K through 12 participated in the 2009 "Survey". In addition, public school principals and teachers, and thought leaders in education took part in an online strategy session as part of the "Survey" development process. Appendices include: (1) Methodology; and (2) Questionnaires. (Contains 24 figures and 26 footnotes.)
