The case study of the Excellence Project under the main supervision and co-operation of the German-Thai Chamber of Commerce and German International Cooperation under the project title German-Thai Dual Excellence Education (GTDEE) will be selected. It is generally acknowledged that Thailand is trying to adopt the dual system of education, which is a highly-international accepted vocational education management system and has a prototype from Germany. Such efforts have been genuinely used in practice, but in the form of modification, not the entire system used due to legal restrictions, supporting regulations, including there is no any legal obligation for Thai vocational education sector, Industry Federation, the Chamber of Commerce, and industrial sector or establishments to completely commit to the entire dual system of education similar to Germany. But the above reasons, in the matters of incompletion of the regulation, Laws, or legal ties between related sectors, also make the researcher suspicious, as in fact, the dual education system has been officially started for more than 60 years. In 1959, there was an establishment of the “Thai-German Technical School”, with the assistance of the Federal Government of Germany in both economic and academic matters. It is regarded as the beginning the dual system of education was used to train Thai mechanic students for the first time. But, why the readiness is unavailable till these days? Therefore, the comparative study of “Thai-German Technical School” and GTDEE” project should be a challenging topic which is a good comparative and responds to the objectives of this research most.
