This paper describes an approach that states and local districts might use to develop a coordinated assessment system so that information collected at state and local levels about programs under Title I of the Improving America's Schools Act (IASA) would be complementary and not redundant. The reauthorization of Title I provides a unique opportunity for states and districts to work together to develop the assessments mandated for Title I accountability. A coordinated set of assessments must be designed so that assessments used at different levels of the educational system fit together to provide a more complete picture of student achievement than one assessment could provide alone. It will be essential to consider the purposes of the assessment and the achievement information different users of the assessment will need. An example of a coordinated assessment system is presented, emphasizing what the state must develop and what the local district must do. An approach that is both top-down and bottom-up must be developed to reflect the various audiences for assessments. Steps are presented to result in a cross-level coordinated assessment system. These include: (1) state and local standards coordination; (2) development of the assessment blueprint; and (3) developing performance standards. Two attachments describe the purposes of assessment and its formats. (Contains two figures.) (SLD)
