This guide contains information to help teachers understand and use reports from the Delaware Student Testing Program (DSTP). The DSTP is designed to be a measure of progress toward Delaware's content standards that helps ensure that students can apply their academic skills to realistic, everyday problems. The DSTP aims to promote better instruction and curriculum and to identify student weaknesses. In spring 2001, the DSTP tests were given in reading, writing, and mathematics at all tested grades, and the science and social studies tests were administered in grades 8 and 11, with the grades 4 and 6 science and social studies tests scheduled for October 2001. The first section of this report introduces the DSTP and its reports and answers some commonly asked questions. The second section focuses on the English Language Arts report, discussing the grades tested, testing dates, test form used, and norms. Score comparisons, percentile ranks, instructional needs, and performance levels are discussed. Section 3 contains similar information for the mathematics report, and section 4 describes the science and social studies report. Section 5 contains a discussion of understanding reading and mathematics in grades 2, 4, 6, 7, 9, 11, and 12. An appendix contains sample reports. (SLD)
