WAI assesses attitudes and behaviours that are difficult to elicit using other methods. Its innovative format ensures its validity when used in a selection or screening context. WAI is available for supervised or unsupervised administration, and can be used on its own or as part of a battery of work relevant assessments.

The WAI avoids the risk of circularity, having been subject to a number of field trials and experimental simulations which have been shown to demonstrate an ability to predict meaningful criteria.
