DIMPACK - Nonparametric Dimensionality Analysis Package
This new Windows package includes DIMTEST, DETECT, and HCA/CCPROX for dichotomously scored data. DIMTEST 2 is a hypothesis testing procedure that assesses lack of latent unidimensionality for an educational or psychological test, operating in a confirmatory mode or in an exploratory mode. DETECT nonparametrically provides a detailed dimensional description of a test in which the items are grouped around several distinct reading passages or underlying psychological or cognitive constructs; DETECT also operates in either a confirmatory or an exploratory mode. HCA/CCPROX performs a latent multidimensionality-sensitive hierarchical cluster analysis on dichotomously scored items, allowing the user to examine the test’s dimensionality at a variety of agglomeration levels.
The new Windows interface in DimPack facilitates selection of program options and provides ready access to help documentation.

LERTAP 5
Lertap 5 is a classical item, test, and survey analysis system which has continually been refined and updated for the last decade. 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 new version for use with Excel 2007 (Windows XP or Vista required) is ready for users to try.

Statistical Theories of Mental Test Scores
One of the most important books in the history of psychometrics has been virtually unavailable to scholars and students for decades. 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.

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.
