- Summary:
-
With the advent of computer-based testing (CBT) and the need to increase the number of items available in computer adaptive test pools, the idea of item variants was conceived. An item variant can be defined as an item with content based on an existing item to a greater or lesser degree. Item variants were first proposed as a way to enhance test security by increasing the size of CBT item pools. Variants are now also seen as useful rapid item-creation pools in programs that use paper-based testing exclusively because they also enhance security in that situation. This report summarizes the part played by variants in item pool expansion and item pool security, focusing on types of variants and their appropriate uses and the difficulties for item pool management created by item variants. Attachments discuss a logical reasoning item and medium variants and an analytical reasoning stimulus and medium variants. (SLD)
