This publication is a resource for North Carolina teachers of grade 3 through high school in English Language Arts, Mathematics, Social Studies, and Science. It describes five different ways to use "Item Bank Testlets," the sample test questions created for teachers to match goals and objectives in the state's "Standard Course of Study." These "Testlets" are a selection of multiple-choice and open-ended questions that are available for reading, mathematics, social studies, and science for grades 3 through 8 and for English I, U.S. History, and Algebra I for high school. Suggestions are given for using the "Testlets" for: (1) instructional planning; (2) diagnosis before instruction begins; (3) after an instructional unit; (4) for ongoing review; and (5) to learn how to answer questions. A section on "Unpacking Multiple Choice Items" presents teacher notes and transparencies for the subject areas. A section on "Responding to Open-Ended Questions" gives examples for reading and mathematics. A final section, "Students Taking More Responsibility," contains two handouts for students to use for their own preparation for study and tests. (SLD)
