Use at least two different types of assessment, preferably measuring the same criteria using the same scoring methodology, such as using both the Case Study and the Role-play CPG
. Using only one exercise isn’t advised because it provides a narrow snapshot of performance using a single format, which may not be where some candidates’ skills lie. It puts a great deal of pressure on the candidate, and feedback is less robust (with two exercises you can explore themes and tendencies apparent across two scenarios and formats). Using the average of two assessments improves the likelihood of an accurate representation of candidate performance, reducing the risk of uncharacteristically poor performance in candidates, and thus reducing the likelihood of challenge.
