CITAS is a simple, easy-to-use spreadsheet for non-psychometricians to evaluate the reliability of their items and tests.
CITAS is available for free. Just complete this form and we will send you a link to download. Note that because it is free, we do not provide any support.
More information on the psychometric terms can be found by reading the CITAS Manual.
Simply type or paste your data into an Excel spreadsheet and the statistics populate in real time – no coding or “running” needed. But while simple to use, it still provides essential output with industry-standard Classical Test Theory for small samples.
Need a deeper analysis or have more than 100 examinees? You need Iteman, which automatically creates Word reports with comprehensive graphics and narratives, and far more statistical output. Iteman also comes with a free version for up to 100 examinees.
