The Laboratory for Interdisciplinary Evaluation of Public Policies (LIEPP) is a Sciences Po research platform funded under the “Investments for the Future” program of the National Research Agency (ANR). Created in 2011, this laboratory is redeployed from 2020 in partnership with Université de Paris. 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 many public policies such as education policies, environmental policies, migration policies, health policies, social and socio-fiscal policies. They address, in a transversal approach, the dimensions of public policies of major societal issues, such as environmental risks, inequalities, discrimination, the crisis of expertise and democracy.

LIEPP is based on an innovative evaluative research approach, combining quantitative, qualitative and comparative methods, and combining a high level of scientific requirements with the concern for the dissemination and translation of research results among public actors.

Through its activities, LIEPP works to better anchor the approach of evaluation in academic research in the social sciences. But it also works in connection with experimental sciences, particularly in the context of collaborations between University of Paris and Sciences Po, to better connect this knowledge to their consequences for public action. Finally, in the sphere of public policy, it contributes to the public debate and reflections on evaluation involving other actors (administrative, parliamentary, associations, etc.), with a view to promoting the process of evaluation and improving its quality.

All the projects carried out at LIEPP benefit from the support provided by the ANR and the French government under the “Investissements d’Avenir” program LABEX LIEPP (ANR-11-LABX-0091, ANR-11-IDEX-0005-02) and the IdEx Université Paris Cité (ANR-18-IDEX-0001).
