It is intended for those with little or no background in either IRT or CAT/CCT and will focus on the basic IRT and CAT concepts necessary. The workshop will provide a foundation from which attendees can perform IRT analyses and begin to implement their own CATs. Note: Registration is now open. Price Depends on Options CAT/IRT Workshop - 1 June, 2009 - Minneapolis, Minnesota Introduction to Computerized Adaptive Testing Monday June 1, 2009 On the Minneapolis Campus of the University of Minnesota Held prior to the: 2009 GMAC Invitational Conference on Computerized Adaptive Testing Tuesday, June 2 and Wednesday June 3, 2009 This pre-conference workshop is designed for individuals who desire an introduction to computerized adaptive testing (CAT) and the item response theory (IRT) that supports its implementation. It is intended for those with little or no background in either IRT or CAT and will (1) focus on the basic concepts necessary to understand the conference presentations, and (2) provide a foundation from which attendees can begin to implement their own CATs. Note: Registration is now open. Price Depends on Options Arpeggio Suite - Software for Cognitive Skills Diagnostic Assessment Diagnostic appraisals of examinee ability on multiple skills or multiple facets of understanding are often required in educational assessment, especially in formative assessment settings, and represent one of the most important lines of research in measurement today. The Arpeggio Suite is a statistical analysis package that runs in Windows, and is the first assessment package specifically designed for this cutting-edge type of analysis. Using the Fusion Model, a sophisticated and flexible IRT model developed for such analyses, Arpeggio classifies examinees as masters or nonmasters of the user-specified skills and provides information regarding the discrimination of items and the test as a whole with respect to those skills. Arpeggio is ideal for educational measurement research concerning skills diagnostics as well as for applied educational assessments where skills diagnostics are required to provide greater examinee feedback. Price Depends on License Options LERTAP 5 Lertap 5 is a classical item, test, and survey analysis system which has continually been refined and updated for the last decade. Now updated for Excel/Office 2007. And now with new functionality to import ITAP-formatted input files. An Excel-based application, Lertap 5 produces a variety of tabular reports and related graphics. Lertap extends the features commonly found in classical item and test analysis programs by providing support for users of mastery, licensing, and certification tests. It also has comprehensive routines for detecting test cheating. A particular strength of Lertap is its incorporation of graphical portrayals of results, including quintile plots of distractor functioning, boxplots of group test scores, eigenvalue scree plot displays, score histograms, and scatterplots. Lertap also computes conditional standard errors of measurement and indices of classification consistency. Backed by extensive documentation, Lertap runs on both Windows and Macintosh systems.

A gap in the archives of modern test theory is now being filled by the release in paperback for the first time of the classic text, Statistical Theories of Mental Test Scores, by the late and honored statisticians and psychometricians, Frederic M. Lord and Melvin R. Novick. No single book since 1968 when Lord & Novick first appeared has had a comparable impact on the practice of testing and assessment. Our price: $59.99 Psychometrics: An Introduction In Psychometrics: An Introduction, authors R. Michael Furr and Verne R. Bacharach center their presentation of material around a conceptual understanding of psychometric issues, such as validity and reliability, and on purpose rather than procedure, the “why” rather than the “how to.” Their goal is to introduce psychometric principles at a level that is deeper and more focused than found in introductory undergraduate testing and measurement texts but that is more intuitive than traditionally found in the more technical publications intended for graduate courses. By emphasizing concepts over mathematical proofs and by focusing on practical significance, this book assists students in appreciating not just how measurement problems can be addressed and why it is important to address them. Our price: $89.95 Improving Testing: Applying Process Tools and Techniques to Assure Quality Improving Testing demonstrates how proven quality assurance tools and methods that have been applied successfully in the manufacturing and service industries for the past 20 years can be applied in the testing industry. It defines what is meant by the term "quality" in testing and reviews how three business process concepts-standards, process planning and design, and continuous improvement-can be used to improve the way in which tests are designed, administered, scored and reported so that errors can be eliminated. Our price: $49.95 Technology and Assessment: The Tale of Two Interpretations Technology and Assessment examines technology and assessment from both perspectives by examining past, current and promising methodologies and applications in both fields. The influences instructional uses of technology and the increasing reliance on testing to gauge student and school performance have on one another are also explored.
