Is there any format for describing tests?

Question

Standardization

In the field of education automation, there are SCORM and Tin Can API specifications. Is there something similar or some standard or format for describing and storing tests (in particular, psychological ones). On the Internet, you can find many tests implemented in the form of applications, as well as programs and services that allow you to create your own tests. But I could not find such an application in which you can download ready-made tests in any format.
Question: is there any format for describing tests and, if so, where can I download such tests (for example, Amthauer)
