Xcalibre 4 updates
Xcalibre 4is the most user-friendly software available for item response theory (IRT) analysis.  An update has been recently released, which includes a number of bug fixes and enhancements, including an addition of distractor (quantile) plots into the output.  These plots provide an excellent method for evaluating multiple-choice distractors by combining IRT and classical test theory.  We have also added a new fit plot with standard errors to the report document and percentiles to the scores spreadsheet.  Current license holders can download the no-cost update from https://assess.com/xcart/pages.php?pageid=10.  If you do not yet have Xcalibre 4, a free demo version is available at https://assess.com/xcart/product.php?productid=569.

Iteman 4 updates
We have also released an update for Iteman 4, the leading software for analysis with classical test theory (CTT).  This update focuses on bug fixes and maintenance.  If you have a current license, you can download the update at https://assess.com/xcart/pages.php?pageid=10.  If you do not yet have Iteman 4, a free demo version is available at https://assess.com/xcart/product.php?productid=541.

Conferences page on ASC website updated for 2012
ASC provides a number of resources to professionals in the field of testing and psychometrics, including a list of major conferences in the field.  We have updated that list for 2012 at https://assess.com/conferences.php… see where you want to go!  ASC has plans to be at the SIOP, IACAT, and ICE conferences.

Connect with ASC on LinkedIn

Free training videos released
ASC hosts one or two workshops every year (one workshop was just recently held, January 23-25 in Brazil) and presents at a number of conferences, but we realize that not everyone is able to attend.  Therefore, ASC is publishing a set of tutorial videos on our software and important issues in psychometrics, like item response theory and computerized adaptive testing.  The videos are available for free at https://assess.com/tutorials.php.  Two have been completed so far: Running Iteman 4 and Interpreting Iteman 4 Output.

ASC to present at 2012 SIOP Conference
ASC will present a mini-workshop on the development of computerized adaptive tests (CATs) at the Society for Industrial-Organizational Psychology (SIOP) conference.  The session is scheduled for 1:30 PM on Friday, April 27.  More information is available at the SIOP website.
