France replaced the university place lottery with a matching algorithm.
Parcoursup (2018) swapped a random draw for preference-based matching, with quotas to lift scholarship students into courses.
French Ministry of Higher Education
the move
France's prior system, APB, allocated places at oversubscribed public universities partly by lottery, which ministers saw as unjust and wasteful given high dropout. The government wanted to match students to courses they actually chose.
Parcoursup, launched for the 2018 admissions round, replaced the draw with a matching algorithm. Applicants rank their wishes; each institution ranks applicants; the platform runs a deferred-acceptance-style procedure in rounds, with universities holding their preferred candidates and releasing the rest, so offers cascade until the system settles.
To keep access fair, the platform also builds each course's calling order from the academic ranking while promoting a minimum proportion of scholarship-holder (boursier) applicants. It was meant to make admissions honest and efficient instead of random.
why it works
- A lottery ignores how much a student wants or fits a course
- Ranked choices let students state true preferences without gaming
- The deferred-acceptance process settles to a stable match of offers
- Scholarship quotas inject fairness into a merit ranking
what transfers
A mechanism that reveals preferences beats a lottery, but only if it is legible; Parcoursup's opaque 2018 rollout eroded trust in an otherwise sound algorithm.
what came after
The 2018 rollout was messy: not enough applicants accepted offers promptly, so universities could not count enrollments as term began, and critics called the algorithm opaque. The platform kept the mechanism, published more about its rules, and became the standing route into French higher education.
