On the Enquette Setup page, at the Tab Evaluation Schemata, you can check, create, edit and delete evaluation schemata used by Evaluation Controls.
An Evaluation Schema is basically a set of associations between verbal terms (Marks) and their numeric equivalents as used e.g. by Dropdown control. In a multilingual environment, verbal terms vary depending on language selected, whereas their numeric values remain the same.
The Schema may be a global one usable in all Enquettes, or an Enquette specific one.
A Schema may contain Options. They display along with a brief description and controls they affect. A Schema may contain just Options without term-value associations (like min and max for Numeric control).
