The French teacher training system was originated from the "Guizot Proposal" proposed in 1833. In 1989, Lionel Jospin, the former Minister of Education, announced the "Education Guiding Proposal" and then, in 1990 he presented the "Teacher's Training Institution" (Institut universitaire de Formation des Maitres (IUFM). It was formally accepted and took over the role of the Normal Schools system. Such institution is quite effective in cultivating French future elementary and secondary teachers. Despite this fact, there were still callings for education reform due to the too abstract and less practical characters of the Teacher's Training Institution which were incapable to meet the future needs for managing all classes. As consequence, motivated by the current Principle Gilles de Robien, a movement of implementing the system, the so-called Future School guiding planning Proposal (loi d'orientation et de programme pour I'avenir de l'ecole) is coming into being. The regulations (89 rules in all), formally announced on the 23th April, 2005, were the most important and the largest educational reforming plans so far. Its contents included all aspects of the cultivation of elementary, secondary teachers. Among the rules, the 85th rules specifically stated that IUFM has to be merged and become one of its regional universities. That was a great change to French Teacher's Training System. This article studies all available articles relating to the teacher's training reform, and analyzes the effects of its implementation.
