Meetings 2004 CCSSO Brain Trust on Use of Growth Models Based on Student-Level Data in School Accountability
Selected Resources This memo is designed to answer many of the current questions about what growth models for accountability are, and what they are not. It discusses growth models in relation to status and improvement models and summarizes the following: 1) types of growth models and their purpose(s); 2) the advantages and disadvantages of growth models; 3) challenges to implementation and resource requirement; 4) use of growth models under NCLB; and 5) policy questions that may shape a state decision regarding the use of growth. Explicitly Valuing Growth, Center for Assessment This presentation emphasizes the need for designers to explicitly state how they value changes in student performance, or growth, for use in school accountability systems. The presentation also provides a practical way to measure and value student growth using vertically articulated standards, and provides suggestions and examples of some key analyses to check whether the student growth system fits the expressed values.. Using data from the National Assessment of Educational Progress (NAEP), this report tracks the performance of groups of individuals from varying demographic groups and states to examine the achievement gap as well as the academic attainment of these groups over time. It explores the problematic nature of examining growth via assessment scores attained at given times.. In this study the authors examine how a handful of innovative schools are using a variety of student performance data to improve the instruction of teachers and the school organization’s support for instructional improvement.. In this report, the authors consider issues surrounding school- and teacher-level use of student data and data-based decision making, describe the state of the field and possible future directions, and present a range of software for data analysis along with software reviews.. Monitoring school performance increasingly uses sophisticated analytical techniques and the authors investigate whether one such method, hierarchical growth modeling, yields consistent school performance results when different metrics are used as the outcome variable. In this paper, Robert H. Meyer discusses mathematics achievement data from Milwaukee middle school students to illustrate the value-added approach to estimating school performance. It examines the growth demonstrated by groups of students, and the challenges associated with value-added indicators such as test scores. |
