AssessmentTest:Introduction

QTI Version 2.1 introduced the definition of a test (also referred to as an assessment).

The specification states that

''“A test is a group of assessmentItems with an associated set of rules that determine which of the items the candidate sees, in what order, and in what way the candidate interacts with them. The rules describe the valid paths through the test, when responses are submitted for response processing and when (if at all) feedback is to be given.”''

(Note the mention of assessmentItem in the above definition. This refers to the QTI element which specifies a single item.  For more details refer to the Assessment Item section of this training guide.)

In other words, a test is a logical aggregation of several QTI items. Moreover, a test contains instructions on how to
 * create groups of items within a test
 * shuffle the sequence of items presented to the candidate
 * specify when the candidate may submit answers for response processing
 * relay feedback to the candidate at different points within a test

Physical Representation of a QTI Test
A QTI test comprises
 * one assessmentTest element - which is described in this chapter
 * the set of assessmentItem elements which are referenced in the above assessmentTest. Each of these will reside in a separate external file.

“Logical” - in that a test, as we shall see, does not physically contain entire items – rather it contains reference
 * all the resources (e.g. image files) associated with all the assessmentItems in the assessmentTest

If you wish to import or to export a test, you should create a content package containing all the above components.
