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." - Question and Test Interoperability standard, published by IMS Global.
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.
