Abstract
In this article I will try to clarify discussions about the analytic instruments for system development and the contribution of comparative vocational education theory to international vocational education and training (VET) aid in the Federal Republic of Germany. I will first try to establish foundation for of comparative theory VET. My analysis will especially focus on German aid in the field of Dual Vocational Education and its transfer.The reason why the transfer issue of the dual system is considered is related to necessities which have to be verified in a discussion of the German dual system, a discussion which tends to fall in a period after the 1990's. Also, I would like to analyze this topic because Germany is the most energetic of all developed countries in the field of vocational education aid.
