CITAS: Classical Item and Test Analysis Spreadsheet
CITAS is a simple spreadsheet for non-psychometricians to evaluate the quality of assessments with classical test theory.
CITAS is an easy-to-use tool for implementing classical test theory on small data sets, designed to provide a straightforward and no-cost way for non-psychometricians to evaluate the quality of assessments. If you are using assessments but not evaluating their statistics, you have no way of knowing whether your test is reliable.
CITAS is intended for anyone that is new to psychometrics and wants a simple tool to help learn the analytics. It’s limited to 100 examinees and 100 items.
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.
Need more power? For professional-level analytics or larger data sets, check out Iteman. Iteman also comes with a free version for up to 100 examinees.
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.
More information on the psychometric terms can be found by reading the CITAS Manual.
