This guide contains materials to help Delaware educators understand and use reports from the Delaware Student Testing Program (DSTP). The DSTP tests are tied to the Delaware content standards that define the knowledge and skills required for students to progress beyond high school. In spring 2003, the DSTP reading, writing, and mathematics tests were administered, with the science and social studies tests given in grades 8 and 11 in the spring and in grades 4 and 6 in October. Section 1 of this guide is an introduction to the DSTP, and it also discusses the various types of report generated by the testing program. Sections 2, 3, and 4 discuss the English Language Arts, mathematics, and science and social studies tests respectively. Section 5 describes the Diploma Index, which determines the type of diploma a Delaware high school graduate will receive. An appendix contains 10 sample reports. (SLD)
