The use by interviewers of a deliberate, prearranged, and consistent overall structure, comprising warm-up, level check, probes, and wind-up, can strengthen the content validity of interview tests. Moreover, the flexibility necessary for elicitation is increased if an established battery of well-structured tasks exists for candidates to perform. However, consistent use of the same topic in several interviews could lead to test compromise. Therefore, it is recommended that underlying types of tasks and questions be used repeatedly, but with different topics in different interviews, thus maintaining content validity and flexibility but avoiding test compromise. It has been found that certain question types are useful at specific levels for eliciting specific types of response. Samples of these question types are presented for Levels 0+, 1, 2, 3, and 4. A checklist, called a testing protocol, is included. It shows various tasks and questions drawn together by level. A description of the FSI oral interview rating scale for five levels is appended.
