index - Laboratoire interdisciplinaire d’évaluation des politiques publiques (LIEPP) Access content directly

The Laboratory for Interdisciplinary Evaluation of Public Policies (LIEPP) is a research platform at Sciences Po funded under the "Investissements d'avenir" programme of the French National Research Agency. Created in 2011, this laboratory is being redeployed since 2020 in partnership with the University of Paris (UP). Its aim is to develop the evaluation of public policies through an interdisciplinary scientific approach. The research carried out at LIEPP analyses the functioning and effects of numerous public policies such as educational policies, environmental policies, migration policies, health policies, and social and socio-fiscal policies. They address, in a transversal way, the public policy dimensions of major societal issues, such as environmental risks, inequalities, discrimination, the crisis of expertise and democracy.
