This report is the sixth of a series of reports having to do with item studies of the Sequential Tests of Educational Progress (STEP) regularly administered to students in grades four, six, eight, ten, and twelve enrolled in the public school system in Hawaii. The item study summaries prepared for achievement tests administered at the various grade levels involved fifteen separate tests, 900 test items, and 65 thousand individual students. Since each student took three achievement tests, an item count was made for approximately 196 thousand students. This report is in two sections: Part I presents the item study summaries by grades and subject areas for the state; Part II presents the item study summaries by grades and subject areas for each of the seven districts.
