This study uses data from surveys of U.S. employees to determine whether any trends are apparent in the proportion who say they receive some form of training at work. Discussions of economic change in the U.S. and elsewhere have frequently asserted that work has become more intellectually demanding. This implies that training in workplaces should have become more prevalent. However, the survey data do not reveal any overall trend in the prevalence of workplace training between 1970 and 2000. There did appear to be a rising trend for women, evidently reflecting women's increased representation in professional and managerial occupations. Throughout this period, more highly educated workers are more likely to say they receive training at work.
