A research project examined ways in which labor market signals and indicators were being used and might be used to identify needs that could be met through national Technical and Vocational Education and Training (TVET) systems. Three case studies were undertaken in Bangladesh, Zimbabwe, and Costa Rica. The studies used a matrix that identified on one axis a number of key user groups of Labor Market Information (LMI) and on the other axis a series of questions or issues. A fourth case study was undertaken in Cambodia, and investigated ways in which an LMI system might be established there. Findings indicated no clear patterns of reasons for collection of LMI. Most data were quantitative. Formal, quantitative labor market data were collected mainly by research units within government departments. In each country, several ministries collected their own LMI, without reference to each other and with much duplication of effort. The most common investigative technique was the postal questionnaire survey, supplemented by census information. Only limited examples were found of LMI being used to enhance the short- and medium-term responsiveness of TVET. The benefit most commonly cited of LMI at national and regional levels was in deciding whether and where to site new training institutions. International agencies were the main sources of intervention for improvement of the LMI system. Findings were used to develop a framework for an LMI system. (Appendixes include 87 references, an interview framework, and an example of a LMI schedule. (YLB)
