Tests are not perfect measures of student achievement, and it is important for educators, parents, and community members to understand some of the measurement issues involved in interpreting test score results. The information that follows should help you understand some of the complexities involved in interpreting state tests and understanding how schools are labeled based on their test score results. Our goal is to help educators and the general public make sense of testing and accountability results.
