Argentina has a complete network of more than 700 institutions that train teachers for all levels of the school system. Given the decentralized structure of Argentine education, public and private teachers' training institutions depend on provincial educational administrations.2 According to a 1994 study by Diker and Terigi, this system is characterized by its "heterogeneity, diversity and lack of specificity." In principle, heterogeneity is not necessarily bad, and may be necessary to meet the diverse demands of the system. There are training schools oriented toward the various levels of the educational system and to specialties within it; there are public and private institutes, higher education teacher training, national higher teaching institutes, and also national higher schools of business and national higher schools that among other things offer some kind of teacher training. In addition, training is offered by the universities.
