Statewide exit examinations play an important role in discussions on school effectiveness. Referring to educational governance concepts, this paper presumes a relation between varying organizational structures of statewide examinations across states, and heterogeneous effects on school actors. It is assumed that their ability to affect work in schools depends on how standardized their procedures are. Therefore, their structural elements must be juxtaposed, and their standardization level must be identified. This paper describes the results of a comparative review of statewide exit examinations using the example of 16 OECD-states alongside the categories Historical Context, Organizational Framework, Marking, and Handling of Results, and discusses the examinations regarding their overall standardization. The study is a basis for further research into how differently structured exit examinations affect school work. (Contains 2 tables.)
