Xcalibre: A Smarter Approach to Item Response Theory Software

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

More 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 is a game-changer for IRT software: 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.

Diagnose items with easy-to-read output

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.

How is IRT better than Classical Test Theory?

Stronger Science

Designed specifically to address important psychometric issues

Better Equating

Superior at equating multiple forms/years

Sample-Independent

Classical test theory results are notoriously sample-specific

Better Measurement

More precise scores, for more examinees, makes adaptive testing feasible
