The cost of recruiting poorly assessed workers goes well beyond the recruitment costs themselves. Subsequent training and integration costs need to be taken into account, as does the impact of reduced productivity. Assessment centres can improve the predictability of selection processes by allowing a broader range of selection methods to be used. Employer and candidate both benefit, the latter from being able to better assess the organisation. The Managing Assessment Centres Pocketbook provides a practical insight into the complete process of planning, designing and managing an assessment centre. It includes advice on: job descriptions and person specifications; working with competencies; exercise design; observation, evaluation and rating scales; timetable and venue planning; assessor and candidate management; reviewing assessment results; and, validating the overall investment.
