We are pleased to announce the long-awaited release of ConQuest Version 2.0.

ConQuest is a computer program for fitting item response (Rasch) and latent regression models. It provides a comprehensive and flexible range of item response models that allow you to examine the properties of performance assessments, traditional assessments, and rating scales. ConQuest also offers the most up-to-date psychometric methods of multifaceted item response models, multidimensional item response models, latent regression models, and drawing plausible values.

ConQuest is available with both a graphical user interface (GUI) and a simple command line, or console, interface. The GUI version is available for all Windows platforms. ConQuest comes with a 200+-page comprehensive manual that includes tutorials on the various types of Rasch analysis that it supports.

ConQuest version 2.0 incorporates many enhancements to the 1998 version 1.0. These include plots of item characteristic curves, user-defined fit statistics, estimation of population characteristics such as percentages above a cut-point on a scale, and a more user-friendly interface.

You can download from a 30-day trial copy of ConQuest and the Version 2.0 PDF manual.

Book: Assessing and Modeling Cognitive Development in School:

Intellectual Growth and Standard Setting

JAM Press, (click on: JAM Press Books), is pleased to announce this new book which presents a series of papers that examine the area of cognitive modeling in assessment with a particular emphasis on standard setting. These papers present the most up to date information on modeling student learning using multivariate IRT models, progress variable mapping, value-based approaches, content trajectories, on line tutoring records, and vertically articulated performance standards.

The No Child Left Behind (NCLB) legislation has encouraged a keen interest in standard setting. At the same time, there has been a steady increase in the use of cognitive models to understand student performance. These models are being used to characterize the patterns of problem solving that a student utilizes to solve the test items with which he or she is faced in an assessment. This book combines these two interests in a way that gives the reader an overview of the current literature as well as the issues that remain unresolved. This book helps one to understand the standard setting problem as one of characterizing the expert student's problem solving strategies and differentiating these strategies from those used by the inexpert student. The result is a view of standard setting and student progress that takes on a very different appearance from that traditionally used in psychometrics.

This book is based on the very well received conference of the same name held on the University of Maryland Campus on October 19 and 20, 2006.
