This paper outlines the rationale and basic design for the development of a state-based network for improving indicators of precollege science and mathematics education. The historical background for improving the indicators of the federal and state levels are described. Five elements of a conceptual framework for the network are discussed. These include: (1) "Defining and Identifying Indicators"; (2) "Current Goals for Improving Science and Mathematics Education"; (3) "Using Existing Frameworks and Model Indicators"; (4) "Building on the CCSSO Model of Educational Indicators"; and (5) "Responding to Needs of States." Three phases of this project are discussed. Six categories of the indicators of science and mathematics are listed and described, including student outcomes, instructional time, curriculum content, school conditions, teacher quality, and resources. A total of 15 references are listed. (YP)
