This summary for administrators describes the Iowa Tests of Educational Development (ITED), which are broadly based achievement tests for grades 9 through 12. The seven tests in the battery provide information about students' development in skills that are among the fundamental goals of secondary education. Emphasis is on the objectives that represent the long-term goals of instruction. The seven tests are: (1) Test E--Correctness and Appropriateness of Expression; (2) Test Q--Ability To Do Quantitative Thinking; (3) Test SS--Analysis of Social Studies Materials; (4) Test NS--Analysis of Natural Science Materials; (5) Test L--Ability To Interpret Literary Materials; (6) Test V--Vocabulary; and (7) Test SI--Use of Sources of Information. Tests are presented in two overlapping levels, Level I for grades 9 through 10, and Level II for grades 11 through 12. A description is given of each test, and some sample questions are included. Test development, scoring, and support materials for test interpretation are reviewed. The ITED battery was standardized in April and May of 1988 with more than 17,000 students. Reliability and validity are discussed, and the score reports furnished by the publisher are reviewed. (SLD)
