Summary

The task-based model presented here with its four task types is not set in stone, but may help you to decide which interactions to use in which of your test items.

In parts 2-5 of this course, each of the four task types (and any sub-types there may be) will be considered in turn in much more depth. The interactions that can be used to create test questions for that particular task type or sub-type will be discussed, as well as the differences between them. These differences include those represented by the two differentiators guidance level and language level, but there may also be other differences specific to a particular task type, or set of interactions. Potential reasons will be highlighted which may motivate you to opt for one above the others in a given test scenario.
