“…While multiple definitions of teacher professionalization and professionalism exist and include a variety of factors such as teacher training and education, teacher pay, and teacher collegiality, this study limits the definition of teacher professionalization to autonomy over the technical core of their primary work in curriculum and instruction. The reason for this limitation is that NCLB focused on teachers' practices in curriculum and instruction as the primary lever for achieving the desired policy outcomes (Superfine, 2005;Superfine, Gottlieb, & Smylie, 2012). NCLB placed an emphasis on standardized test scores in mathematics and reading as the primary measure of school quality, and this emphasis led to a narrowing of curriculum to focus on these subjects, frequently at the expense of time spent on non-tested subjects such as science, social studies, and elective courses (Calwelti, 2006;Hursh, 2007;Jacob, 2005;Koretz, 2008;Nichols & Berliner, 2007;Rothstein, Jacobsen, & Wilder, 2008).…”
