This book assesses the impact and implementation of national qualifications frameworks in sixteen different countries. It presents two major lessons for policy makers thinking of introducing a National Qualifications Framework (NQF). First, that an NQF is only a way of framing existing provision; it cannot on its own, lead to the acquisition of skills or knowledge. Second, as an attempt to standardize learning- something that is only to a limited extent standardizable, NQFs have disadvantages as well as advantages. The research was funded by the International Labour Organization (ILO) and the European Training Foundation (ETF) and, partly as a result of the ILO/ETF Report, the Editors were asked by the World Bank to help them in advising the government of India on introducing a NQF for vocational qualifications. Building on the findings of the report, the editors of this book presented an NQF implementation strategy to the Government of India on behalf of the World Bank. It laid out the steps and stages that would be involved and took account of the earlier experiences of introducing an NQF. Although this strategy was prepared specifically for the Government of India, others who have read it felt it deserved wider circulation. The report has therefore been included in this volume. Since this research was undertaken, the number countries, especially developing countries, implementing or introducing a NQF has continued to increase. This book will be of interest to policy makers and researchers. This book was originally published as a special issue of the Journal of Education and Work.
