The Wisconsin Pupil Assessment Program is a testing service which provides the State of Wisconsin with: (1) a measure of student performance in selected academic areas by developing objective-referenced tests in reading, mathematics, economic understanding, and writing; (2) a comparison of Wisconsin public school students to the rest of the nation in mathematics, reading, and language by administering a standardized norm-referenced test; and (3) a description of student scores over a period of years by reporting annually trends in performance on the above-mentioned tests. Further, the service allows public and private schools who voluntarily use its products and processes to administer the objective-referenced tests used for purposes of statewide assessment. An overview of these statewide tests is provided and the test objectives in mathematics, reading, writing, and economic understanding are listed. All tests are identified with specific grade levels, but they can be administered at other levels. A general discussion on whether to test all students or select a random sample is given. Guidelines for the setting of performance standards for test objectives are provided and five methods which might be used are described. (AL)
