Each participant was assessed against 10 competencies drawn from the organisation's own framework, using a battery of 6 exercises and two psychometric instruments: a 45-minute behavioural event interview, a written case study, an in-basket simulation, individual role plays with an assessor playing the counterpart, and a group activity set in a board-meeting scenario.
Psychometric instruments were administered ahead of the centre. The five assessors worked from five parallel assessment rooms against a scheduling matrix that mapped every assessor to every assessee and protected the preparation time each exercise required.
60 minutes before the case study and the in-basket, 30 minutes before each role play. On the second morning, each batch of 15 split into groups of eight and seven for two simultaneous group activities, observed by three assessors and two respectively.
