A news story with an unusually detailed account of school choice algorithms discusses some of the issues in Latin America, in Spanish, in BBC News Mundo. (Google translate does an adequate job...). One of the issues discussed is that geographic priorities for schools give wealthier families an advantage, and perpetuate geographic segregation.
Qué es el Mecanismo de Boston y por qué expertos denuncian que hay segregación en las asignaciones de escuelas en América Latina Analía Llorente BBC News Mundo
[G translate: What is the Boston Mechanism and why experts denounce that there is segregation in school assignments in Latin America]
Some snippets:
"The Boston mechanism allows for a lot of parenting strategy and that means that it generates a lot of inequalities " [says] Paula Jaramillo, Associate Professor in Economics at the Universidad de los Andes in Colombia
...
"The criticism is against the Boston Mechanism because it continues to be applied, but it is also against the deferred acceptance method because it is generating segregation at the neighborhood level," says Caterina Calsamiglia, a leader in the investigation of these methods.
"The specialist refers to the fact that a student obtains more points for his proximity to the preferred school, therefore he has a greater chance of being admitted to it.
"This creates one of the main strategies is the moving neighborhood, decision can only carry out families with middle income to high, creating inequality."
...
"In many places in Latin America the selection method is not even regulated, and where it is, they are not very transparent with parents in communicating the methods.
"We know a lot about what is done by cities in the United States, in Europe, in Asia, we don't know so much about Latin America," says Paula Jaramillo.
...
"In conclusion, the experts believe that there is no magic method that can be applied uniformly in the countries of the region to avoid segregation and inequality in school selection.
"They agree that the deferred acceptance method is the "fairest" but not perfect. There are many factors to take into account from the quality of the schools to their location."
