Part of George W. Bush's new No Child Left Behind Act requires that a "highly qualified teacher" must be present in all classrooms. Teacher quality has long been an area of interest for scholars in the field of education, and this most recent paper from the Educational Policy Analysis Archives looks at various techniques utilized by different states and school districts designed to strengthen their respective teaching forces. Authored by Linda Darling-Hammond of Stanford University and Gary Sykes of Michigan State University, the paper argues that teacher supply policy should attract well-prepared teachers to districts that sorely need them, while relieving shortages in fields like special education, math and the physical sciences. The paper begins by examining three common misunderstandings about teacher issues, then proceeds to discuss issues affecting teachers such as job satisfaction, retention rates, and the increasing shortages in certain subject areas.
