By 2012, all of the states in this study had started implementing new or revised teacher and leader evaluation systems. There are many and varying updates to these systems, and some of them have been made to meet conditions for a state's federal "Race to the Top" (RTT) grant. Other updates have been made to meet conditions for a state's waiver for certain provisions of the Elementary and Secondary Education Act (ESEA, currently known as "No Child Left Behind"). The following profiles examine one particular aspect of states' new teacher and leader evaluation systems: how states integrate the higher expectations for student learning inherent in the Common Core within the systems' requirements for continuous improvement of teachers and principals. Essentially, these profiles ask, what measures within state teacher and leader evaluation systems generate information that sharpens understanding of teacher and principal performance in terms of their implementation of, support for, and effect on student learning of the Common Core?
