Most studies that discuss labour market information (LMI) as it relates to career decision-making report on the positive impact of computer-assisted programs were carried out before the Internet became a part of our information environment. These studies show that LMI has an impact on career development, but that it is virtually non significant unless transmitted through a counsellor. Indeed, the use of LMI with the assistance of a counsellor appears to be more effective than a computer-assisted program. An evaluation of the level of complexity indicates the effort required to process a large amount of information and its impact on people's ability to discriminate among occupations. It is also frequently noted that the desired information is linked to the interests expressed by people, even though other information could be used to make a well-informed decision. Lastly, the quantity and quality of information are important factors to take into account when one wants to disseminate LMI.
