The assessment needs to be engaging for Study members and well-balanced across the day to avoid fatigue or boredom. The assessment staff must be well-trained and professional at all times. If one grumpy staff member deals poorly with a Study member, this risks alienating that Study member, and potentially their friends who are also in the study, forever. To ensure staff members remain fresh, week-long breaks are programmed into the assessment phase, and social events occur regularly to keep staff morale high.
