6 This level of evaluation assesses the impact the event has had on the individual's performance. The best time for this evaluation is 4 to 6 months after conclusion of the learning activity so that individuals have had time to put what they have learnt into practice. Methods of evaluation could include:
■ structured interviews with participants and their line managers;
■ questionnaires to participants and their line managers;
■ estimates of the benefits of learning;
■ 180° and 360° feedback; and
■ the contents of the organisation's appraisal/ performance management systems.
