Classification Scheme for Items in CAAT.
Epstein, Marion G.
In planning the development of the system for computer assisted assembly of tests, it was agreed at the outset that one of the basic requirements for the successful initiation of any such system would be the development of a detailed item content classification system. The design of the system for classifying item content is a key element in systems development. Without an adequate classification system, it would be impossible to write test specifications and assemble tests that sample required content areas consistently and without undesirable redundancy. This system has a unique identification number for each item and its classification, the computerized file contains a complete history of the previous uses of the item, up to five sets of statistics including difficulty level and discrimination index, codes for the security level and present activity status of the item and up to 15 12-letter key words--which in the case of some verbal items constitute the complete item. Whether the whole items are stored in the computer or remain in a card file for manual retrieval, the selection process of surveying the pool of eligible items and selecting appropriate ones is the same.
