This paper analyses the involvement of academic political scientists in Spain in political and policy advisory tasks and the factors that account for such engagement. This is done by using data from the ProSEPS COST Action survey collected among political scientists working in Spanish academic institutions during 2018. After describing both the contextual opportunities and limitations affecting the demand and supply of policy and political advice in Spain, the paper investigates the factors that could explain the frequency and causes of the engagement of political scientists in policy advice activities. Results show that the structure of the state as well as professional norms, the stage in professional career (seniority and tenure), and the level of specialisation influence the participation in advisory tasks. The paper ends with a reflection about the possibilities to further expand the advisory influence of Spanish political scientists.
