Ministerial advisors have become an essential aspect of executive branches worldwide, thus making the ministerial advisor office a potential route for young politicians aspiring to an expanding political class. The article studies which professions ministerial advisors migrate to following their ministerial careers, how ministerial advisors’ post-ministerial careers compare to their pre-ministerial careers, and if the variance in careers can be explained by the resources that ministerial advisors obtain while in government. Empirically, the article draws on a cohort of 139 ministerial advisors in Norwegian governments between 2001 and 2009; it covers positions in the political sphere and the public, private and voluntary occupational sectors over a period from each ministerial advisor’s youth to the end of 2017. The bibliographic data are combined with surveys and elite interviews. The results show that more than expanding the political class as a recruitment ground for future Members of the Parliament and ministers, ministerial advisor appointments serve as stepping-stones to careers outside of politics. Most ministerial advisors experience shifts between occupational sectors and upwards to higher positions. However, ministerial advisors’ attractiveness in the labour market is surprisingly unaffected by what they actually did in office; rather, it rests on resources such as insider knowledge and networks.
