Emphasis is also placed on rigor will also be identified while raising the curriculum standards in the United States to a competitive international level. The purpose of this research is to examine the results from the Common Core Assessment completed in the States of New York and Kentucky. The Common Core Assessment resulting from these states were selected because a review of the literature determined that these were the two States in the United States that have reported test results. Specifically, this paper will review assessment results and provide an opinion on the future implementation of Common Core Standards in the United States.展开更多
