This article discusses the different ways by which competences of Citizen Scientists acquired by participation in practical archaeological fieldwork can and are being recorded. It illustrates how these different - some more informal, other more formal - means of recording allow to assure professional archaeologists that volunteers who have applied for joining their fieldwork projects possess the necessary skills and competences required; or alternatively assess the amount of supervision and training that will be required to accommodate participation by volunteers who have achieved different levels of competence in different fieldwork skills. It is discussed whether the best practice examples from British archaeology could be adopted within the currently existing legislative framework for archaeological heritage protection in Austria.
