This article analyses the factors affecting access and permanence of the governmental political elite in Chile from 1990 to 2010, utilising data from a survey of 386 members of the elite who entered the political field. Only 199 cases from the survey qualify as part of the governmental elite. It presents a description of the group, a relevant permanence index, and a logistic binary regression model together with a Qualitative Comparative Analysis (QCA). The results find a homogeneous group, and that the factors affecting access are not the same as those for permanence. It concludes that, although a technical profile facilitates access, political capital and previous participation in think tanks are more relevant for permanence in the highest political positions.
