Laboratory for Interdisciplinary Evaluation of Public Policies (LIEPP)

The Laboratory for Interdisciplinary Evaluation of Public Policies (LIEPP) is a Sciences Po research platform funded with the support of the France 2030 investment plan through IdEx Université Paris Cité. 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 are supported by the France 2030 investment plan through IdEx Université Paris Cité (ANR-18-IDEX-0001).

Interview with Anne Revillard, director of the Laboratory for the interdisciplinary evaluation of public policies (Laboratoire interdisciplinaire d’évaluation des politiques publiques, or LIEPP) since August 2020.

You are taking over the direction of LIEPP after having worked there for several years as a researcher : what role has LIEPP played in your research trajectory?

I am an associate professor of sociology at Sciences Po, where I have been a member of LIEPP and the Observatoire sociologique du changement (Observatory of Social Change) since 2012. My research trajectory is a good example of the impact that a place like LIEPP can have in terms of the emergence and development of new questions. My arrival at LIEPP has indeed marked a turning point in my research: whereas I had previously worked on public policies (in the areas of women's rights, institutional mediation and then disability) rather from the point of view of their definition and implementation, the questions arising from the field of evaluation have contributed to shift my focus towards the question of the consequences of policies for the people they target - a question I have explored based on the concept of policy reception.
