Defining rules for a LOFT section

IMPORTANT: Content rules are mandatory, but you can use psychometric rules if you want to control item difficulty.

You can create content and psychometric rules based on tags and IRT values in tests with LOFT sections. Each test conforms to all content and psychometric constraints, meaning that each test contains different but equivalent content.

This article explains how to define content rules for a LOFT section. For details on how to upload psychometric targets, read Uploading psychometric targets to a LOFT section.
