Iowa Tests of Educational Development

The Iowa Tests of Educational Development (ITED) are a set of standardized tests given annually to high school students in many schools in the United States, covering Grades 9 to 12. The tests were created by the University of Iowa's College of Education in 1942, as part of a program to develop a series of nationally accepted standardized achievement tests. The primary goal of the ITED is to provide information to assist educators in improving teaching. Goals of the ITED Rather than testing a student's content knowledge, the ITED endeavors to evaluate students' skills in a variety of areas, especially based on problem solving and critical analysis of texts. These are considered by the authors of the ITED to be skills acquired across multiple curricular areas and skills that are important for academic success. Within the skill areas evaluated by the ITED, the test is designed to elicit information about a student's current skill level, growth and abilities within each area tested. The ITED is designed to examine and compare a student's ability in several educational fields, including vocabulary, reading comprehension, language, spelling, mathematical concepts and problem solving, computation, analysis of social studies materials, analysis of science materials, and use of sources. Although the test is broken up into these fields, the goal of the ITED is to track the development of the skills and analysis needed in each of these areas rather than the content. ITED Sections Vocabulary The vocabulary section of the ITED focuses on testing the development of students' vocabulary for everyday communication.
