    Test specifications for traditional fixed-form tests—which are used by all but a handful of states currently—include a test blueprint, distribution of emphasis, distribution of item types, statistical characteristics (e.g., DIF, point-biserial correlations), attention to position of equating items, etc.  CAT (computer-adaptive tests) test specifications share much, but also differ in significant ways from fixed-form test specifications.  In addition, the criteria and procedures for doing quality assurance that tests meet the specifications may differ (e.g., for alignment, cuing/conflicts, security, etc.).  This session will provide an overview of CAT test specifications and best practices ways to assure that testing programs meet those specifications.
