Where this test comes from

This is the AI Competency Objective Scale (AICOS) and its short form AICOS-S, developed and validated by André Markus, Astrid Carolus and Carolin Wienrich at Julius-Maximilians-Universität Würzburg.

Both papers are open access under CC BY 4.0, and the questions are used with attribution. The English wording is the authors' own translation; for four questions we realigned the English with the validated German where the meaning had drifted.

The norms come from German-speaking adults recruited via Prolific (N = 2,131). For other populations, and for the English wording, results are approximate.

The self-rating questions are the short Meta AI Literacy Scale (MAILS).
