The team is made up of researchers with a wealth of competences related to research practices, research project conception and design, and the profession of researcher. Because their competences are complementary, the team can work on the essence of research activity, i.e from formulation of research questions to publication. The team's assets are in linguistics, critical analysis, research project design, interdisciplinary dialogue, diversity of scientific disciplines, especially disciplines at the borders with other disciplines like biometry.

Team members are not professionals: they receive initial training during a founding seminar (30 hours), followed at regular intervals by pedagogical seminars ("supervision seminars", two per year).
They are not supposed either to stay within the project for ever: some of them leave to pursue their own objectives and activities or take the leadership of other projects, thus disseminating good practices in project building and scientific communication. New researchers regularly join the team who need to be trained as facilitators.
At supervision meetings, the team discusses the project's objectives, issues, institutional strategy as well as matters related to the team's functioning, ethics, values and mission. The environment based on collective learning and reflective practice thus creates the right conditions for ensuring that the LPR project develops and makes good progress and that all actions taken within and outside the project are coherent and relevant to the issues addressed.

Team members become legitimate through their practice and the trust bestowed on them by the participants. Their legitimacy is also based upon a collective competence known as "professional legitimacy", and expressed in a charter of good practice elaborated by the group.
