This manual describes and explains the commands available in the ITEMBANK package (a comprehensive test item bank). True-false, multiple-choice, short-answer, and essay items, as well as the associated answers, can be accommodated. Content domains and behavior categories exist for item classification. Most menus have instant action. Items and tests are displayed on the screen in a print format. Each item file can have hundreds of items, and the number of item files is unlimited. Items can be printed for easy reference. Statistical data are stored for each item and each test, enabling performance on a test to be predicted. Stored items can be selectively incorporated into a test and a powerful editor allows for easy manipulation of tests. Materials other than items can be easily added to a test. Test questions are automatically numbered. Multiple forms of the same test can be created easily by scrambling or ordering the test questions manually or automatically. Tests and answer keys can easily be printed or displayed. Cross-references between different forms of the same test can be generated automatically. (TJH)
