Abstract: An automated method of assembling computerized adaptive test (CAT) pools of test items is provided. A plurality of item bins is created. Each item bin is associated with a different content domain, and each item bin includes only items associated with its respective content domain. The items in each item bin are grouped into a plurality of individual cells, wherein each item is placed in only one of the individual cells, and each cell includes a plurality of items which span a range of difficulty levels. The grouping is performed by linear programming at the individual cell level. One or more pools of items are assembled from a random selection of cells across the item bins, wherein there is only one cell for each item bin. The CAT is administered by randomly assigning each test taker to one of the pools of items.

Abstract: Automated systems and methods are provided for administering a test to a test taker using multistage testing. The test includes a plurality of different test sections, each test section measuring a different quantifiable trait or skill. At least some of the test sections include a plurality of stages, each stage having a test module. Each test module includes a plurality of test items. A first test section is administered that measures a quantifiable trait or skill which is known to correlate with a quantifiable trait or skill that is measured in a second test section. A score is then calculated for the first test section. The second test section is then administered. The second test section measures a different quantifiable trait or skill than the first test section. The second test section has a plurality of stages, wherein the first stage of the second test section is not a routing stage.
