Parcoursup — France's National University-Admissions Algorithm and Its Decade-Long Transparency Battle

Parcoursup is the platform France's Ministry of Higher Education has used since 2018 to allocate secondary-school leavers to university and other higher-education places nationwide, replacing the earlier Admission Post-Bac (APB) system after APB was criticised for opacity and for breaking ties among oversubscribed courses by random draw. Each higher-education programme ranks its applicants using a 'local algorithm' of weighted criteria, while a national matching algorithm allocates ranked preferences to available places through an iterative, deferred-acceptance-style procedure.

Under France's 2016 digital-republic law and the 2018 ORE law, public algorithms must in principle be disclosed to applicants who request the criteria used to evaluate them.

The student union UNEF sued the University of the Antilles in 2018 over its ranking formulas; the Conseil d'État ruled in 2019 that universities were not required to publish local algorithms' source code, but the Conseil constitutionnel ruled in 2020 that the constitutional right of access to administrative documents requires institutions to publish the criteria used, after the admissions process closes.

Despite these rulings, France's Cour des comptes reported in 2020 that 'the Parcoursup code remains 99% closed,' finding the published parts of limited use for understanding how the process actually functions.

France's Defender of Rights and Parcoursup's own Ethics and Scientific Committee have separately said local admissions committees' criteria remain largely opaque in practice, and academic studies have found the system risks reproducing existing social inequalities in access to selective courses, despite a reform reserving a minimum quota of places for scholarship-holding applicants.
