The Wisconsin Department of Public Instruction has contracted with the Wisconsin Center for Education Research to develop and field test performance assessments in mathematics, language arts, and science. Together with a Wisconsin-developed knowledge and concepts test, the new performance assessments will provide important information about the state's students. These samples of prototype performance assessments describe the assessment's content and present examples of proficient student responses. While they are not polished activities, they do provide a working description of the content and academic expectations in the performance assessment instruments. All of the instruments use the same score categories, ranging from advanced response to not scorable. Samples are included for the mathematics, science, and language arts performance assessments. Questions and answers about their construction and use follow the examples. (Contains 8 figures and 10 references.) (SLD)
