AS TRAINING IS NOTHING LESS THAN A BID TO CONTROL learning, the implication for trainers is inescapable: if we want to establish control over the learning process, then we need, as a basic requirement, to measure what is being learned in any training situation we care to design — we need to measure as best we can the behaviour changes brought about by the training. Only when we have collected such behavioural data are we in any sort of position to start focusing the training towards meeting defined individual and organisational needs.
