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!
What is Xcalibre?
User-Friendly
All options are displayed in a clean, simple interface. No coding skills required!
Automated Reports
Save hours of time – Xcalibre copies and pastes all the tables/graphs into a narrative report for you
IRT Models
Supports all major IRT models out of the box – dichotomous or polytomous
Flexible & Powerful
Analyze large data sets, perform equating studies, improve items with classical distractor analysis
Designed to help more practitioners implement Item Response Theory
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.
Output that is easy to read
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.

Enables CAT
IRT enables computerized adaptive testing (CAT)
Sample-Independent
Classical test theory results are notoriously sample-specific
Better Measurement
More precise scores, for more examinees
