A. FOREWORD
In order to ensure that the LAO PDR grows competitively over the coming years, we need to establish a culture of excellence in everything that we do. This includes, particularly the Education & Employment sectors, as symbolized by Technical Vocational Education & Training (TVET).
Research has shown that countries without a functioning and effective TVET system will lose out in the competitiveness ratings, with a consequence negative impact on growth etc.
