This guide describes the Delaware Student Testing Program (DSTP) and includes information about the program and its results that will be useful for administrators and members of boards of education. In spring 1998, the Department of Education, in conjunction with Harcourt Educational Measurement, began its annual administration of the DSTP reading, writing, and mathematics tests for students in grades 3, 5, 8, and 10 to provide an accurate measure of how students are doing relative to Delaware's rigorous content standards. In spring 2000 the science and social studies tests were administered in grades 8 and 11, and a version of these tests designed for grades 4 and 6 were administered in fall 2000. This guide contains the following sections: (1) "Introduction to the DSTP"; (2)"Understanding the Language Arts Report"; (3) "Understanding the Mathematics Report"; and (4) "Understanding the Science and Social Studies Report." The sections on the subject matter reports contain details about individual, school summary, and district summary reports, score comparisons, performance levels, and instructional needs identified by the reports. Information is also provided for principals, superintendents, and boards of education for using the instructional needs comments. Two appendixes contain sample reports. (SLD)
