To improve skills match in the labour market, the Estonian government has developed a skills forecasting system called OSKA. This new system uses a combination of quantitative and qualitative methods - interviews with experts in different sectors, surveys of employers, data on salaries, the ages of current workers in different jobs - to identify occupations where labour shortages are likely in coming years. So far, studies of five sectors of the economy have been published, with 15 more to follow in the coming years.
