Automatically create item response theory tech reports in MS Word, complete with hundreds of easy-to-understand embedded tables, graphs, and narratives. Navigate a straightforward UI with no 1980s command code. Save psychometrician time and costs!
All options are displayed in a clean, simple interface. No coding skills required!
Save hours of time – Xcalibre copies and pastes all the tables/graphs into a narrative report for you
Supports all major IRT models out of the box – dichotomous or polytomous
Analyze large data sets, perform equating studies, improve items with classical distractor analysis
The point-and click interface means that you spend more time on evaluating and improving your assessment, not fighting with code errors. Simply select your files, IRT models, and other options, then click Run. Supports both dichotomous and polytomous items, including both at the same time.
Clear, concise tables, embedded graphics, and explanatory narratives allow you to easily understand results. Includes comprehensive item response theory analysis at both the item and test level (TIF, TRF, etc.). Classical statistics are added where useful.
Moreover, it is all in Word so you can easily annotate results! Save hours of copy-and-paste from ASCII tables and manually created graphs from other software.
Designed specifically to address important psychometric issues
Superior at equating multiple forms/years
IRT enables computerized adaptive testing (CAT)
Classical test theory results are notoriously sample-specific
More precise scores, for more examinees
Xcalibre 4 is available as a free version limited to 50 items and 50 examinees. This allows you to get familiar with the program immediately, and start learning the advanced methods of item response theory.
