The other two commonest types of test are Work Samples and Job Simulations, although at first glance they do not look as we imagine tests to be.

A Work Sample test is exactly what its name implies – a sample of the work the candidate is required to do. These tend to be used widely in mechanical or practical areas of work. A common example is a typing test where the candidate has to type out some hand-written notes without making any errors within a given period of time. Another example is a fork-lift truck driver moving a set number of pallets from one place to another to within a certain degree of accuracy. If you are invited for a Work Sample test, the chances are you already have some skill in the area to begin with.

Job Simulations look similar to Work Samples and the two are often confused. However, whereas a Work Sample actually involves doing a sample of the activities carried out in the target job, a Job Simulation only simulates those activities involved in the target job.

If our fork-lift truck driver was inexperienced, it would clearly not be wise to put him or her into a fork-lift truck and see how little damage is done! It would be better to measure those abilities we know are involved in driving a fork-lift truck, such as hand to eye co-ordination, spatial awareness and so on, and then use the information obtained to infer how the person might perform in the job once they had been trained. Because of this, Job Simulations are often used when selecting people for training or when they have no direct experience in or specific knowledge of the job in question.

Another common type of Job Simulation is the so-called ‘In-basket’, or ‘In-tray’, which is used for many management-based selection activities. The In-tray simply involves taking the contents of a manager’s typical in-tray and working through them, making decisions as to what to do with each item as you go. These simulations are often used to assess organizational and decision-making ability, and are quite commonly used in management selection. However, you do need the contents of a real in-tray to base the exercise on and these contents can be both numerous and diverse – an entire in-basket could easily fill this book!

In addition, tests like In-trays are very difficult to score correctly because there is often no single correct way to deal with the items. Consequently, they tend to be followed up by a presentation from, or interview with, the candidate during which they explain how they worked their way through the in-tray, what criteria they used for decision making and how they justified their actions.
