IRTlib is a software for the delivery of computer-based tests. The software consists of two components:
- IRTLib Editor: A software for test authors, which is used to configure Studies.
- IRTlib Player: A software for data collections, with which target persons work on tasks that are configured in the form of a Study.
Instructions for installing and setting up both programmes for initial use can be found under Download & Installation.
Before using the IRTlib Software to configure and create deliveries, the assessment content (tasks, instructions, intermediate screens, etc.) must be created in the form of individual Tasks using the CBA ItemBuilder.
The CBA ItemBuilder can be downloaded here: www.itembuilder.de/software
An interactive documentation of the CBA ItemBuilder is available here: cba.itembuilder.de

For the use of the IRTlib software, a context-sensitive program help is stored directly in the application. The documentation with the embedded help is available online on this page and is also available as PDF.
