In the Archives of the Archbishopric of Durango (Mexico) there are a number of documents about concursos de curatos, or priestly concourses, which were used for hiring into vacant parishes and cathedral positions. I read a blog post about another concurso that required two days of analyzing Church documents in Latin, translating and commenting on them in Spanish. It looks like a formalized, competititive hiring process.
When did these competitions run? Who chose the winners?
