Abstract
Centralized school admission mechanisms are an attractive way of improving
social welfare and fairness in large educational systems. In this talk, we will discuss the design and implementation of the recently established school choice system in Chile, which handles the applications of over 500'000 students to around 10'000 schools every year. The Chilean system presents unprecedented design challenges that make it unique. First, it is a simultaneous nationwide system, making it one of the largest school choice problems worldwide. Second, the system is used for all school grade levels, from prekindergarten to 12th grade. One of our primary goals is to favor the assignment of siblings to the same school. By adapting the standard notions of stability, we show that a stable assignment may not exist. Hence, we propose a heuristic approach that elicits preferences and breaks ties between students in the same priority group at the family level. In terms of implementation, we adapt the deferred acceptance algorithm as in other systems around the world.
