In CAT, prior information about student ability is used as a basis of item selection – meaning, as a student answers individual items or sets of items, the upcoming items are selected based on the responses of the already answered items. If the student responds correctly to an item or a group of items, a more challenging item or group of items will be presented. If the student incorrectly responds to the item or group of items, a less challenging item or group of items will be administered. Because of this, CAT provides high levels of efficiency in the assessment of student ability.
Construction of adaptive tests is automated through the Galileo Assessment Planner, which defines the item pool to be used in selecting items for the adaptive assessment. Automated construction allows a district or school to construct customized adaptive tests to meet unique local needs. For example, an educational system may construct an adaptive test to be used in determining placement in a locally designed advanced algebra course. Automated construction increases the testing options available for adaptive testing. In addition, it supports accommodations to continually changing standards which are a hallmark of contemporary education.
