The success of a training programme is largely contingent on the beneficiar
y's training motivation. With a focus on instrumentality and self-efficacy,
we have sought to explain motivation and to measure its effects on variati
on of knowledge acquisition and satisfaction with training. An empirical st
udy of 335 workers sheds light on the importance of age, the role of the hi
erarchical supervisor and the manner in which training is portrayed. Volunt
ary participation, expressed by participation in decision making or conside
ration of requests, plays only a minor role in explaining the success of a
programme.
