What is an Item?
“An item is a set of interactions (possibly empty) collected together with any supporting material and an optional set of rules for converting the candidate’s response(s) into assessment outcomes.”
Items are the basic building blocks for Tests. They may contain a single Interaction (a simple item), or several closely-related interactions, all the same type or of a mixture of types (a composite item). Note that items contain interactions, but are not interactions themselves. (See the Interactions section for a definition of interactions.)
Beyond the interactions contained within them, items may include titles, images, and text, which help the Test-taker understand the expectations and context of the assessment material presented within. Item complexity ranges from simple items with a single interaction to composite items with multiple interactions.
