This document discusses standardized assessment and high-stakes testing. It covers the nature of standardized tests, how they are used and evaluated, issues with implementing No Child Left Behind, and research on the effects of high-stakes testing. Standardized tests are designed to provide consistent, objective measures of student achievement and are used to identify student strengths/weaknesses and for accountability purposes. However, high-stakes testing is controversial and research shows it can negatively impact teaching, curriculum, and student motivation.
