This introductory article offers not only a synthesis of methodological approaches, methods, conceptual considerations and theoretical frameworks that are introduced in the various articles in this special issue, it also reaches beyond this collection in referring to interdisciplinary approaches to the study of vocational education and training (VET) governance. The latter are specifically intended to assist in analysing the role of the individual, political groups or networks in governing VET and potentially determining a VET policy transfer process. The author explains how the study of governance is directly connected to the study of policy transfer and specifically introduces categories derived from the behavioural science in order to substantiate the thesis that existing governance studies have not paid attention to the essential category of the human or social factor. Introduction Experience hath shown, that even under the best forms (of government) those entrusted with power have, in time, and by slow operations, perverted it into tyranny. (Thomas Jefferson) No free government, or the blessings of liberty, can be preserved to any people but by a firm adherence to justice, moderation, temperance, frugality, and virtue; and by a frequent recurrence to fundamental principles. (Patrick Henry) These provocative theses of Jefferson and Henry are intended to underline the significant role that politicians, or, more generally, stakeholders in power positions play in determining and enforcing policies and shaping governance in a country as much as in a system, such as a vocational education and training (VET) system. The success of established governance structures and processes can be measured in terms of the outcomes of a VET system, and in this sense conclusions about the functionality of a VET system would be possible. Nevertheless, it is challenging to entangle which aspects of governance ultimately play a crucial role for the success of a system and which do not. In the end, according to Henry, the balance of various factors determines the democratic functionality of a governance system and allows, in the best case, for its self-renewal. This article is concerned with methodological approaches, methods, conceptual considerations and theoretical frameworks in the study of VET governance. The relationship between governance
