“The term “Ratio Studiorum” is commonly used to designate the educational system of the Jesuits; it is an abbreviation of the official title, “Ratio atque Institutio Studiorum Societatis Jesu”, i.e. “Method and System of the Studies of the Society of Jesus”. The Constitutions of the Society from the beginning enumerated among the primary objects of the Society: teaching catechism to children and the ignorant, instructing youth in schools and colleges, and lecturing on philosophy and theology in the universities. Education occupied so prominent a place that the Society could rightly be styled a teaching order. Even during the lifetime of the founder, St. Ignatius, colleges were opened in various countries, at Messina, Palermo, Naples, Gandia, Salamanca, Alcalà, Valladolid, Lisbon, Billom, and Vienna; many more were added soon after his death, foremost among them being Ingolstadt, Cologne, Munich, Prague, Innsbruck, Douai, Bruges, Antwerp, Liège, and others. In the fourth part of the Constitutions general directions had been laid down concerning studies, but there was as yet no defininte, detailed, and universal system of education, the plans of study drawn up by Fathers Nadal, Ledesma, and others being only private works. With the increase of the number of colleges the want of a uniform system was felt more and more. During the generalate of Claudius Acquaviva (1581-1614), the educational methods of the Society were finally formulated. In 1584 six experienced schoolmen, selected from different nationalities and provinces, were called to Rome, where for a year they studied pedagogical works, examined regulations of colleges and universities, and weighed the observations and suggestions made by prominent Jesuit educators. The report drawn up by this committee was sent to the various provinces in 1586 to be examined by at least five experienced men in every province. The remarks, censures, and suggestions of these men were utilized in the drawing up of a second plan, which, after careful revision, was printed in 1591 as the “Ratio atque Institutio Studiorum”. Reports on the practical working of this plan were again sent to Rome, and in 1599 the final plan appeared, the “Ratio atque Institutio Studiorum Societatis Jesu”, usually quoted as “Ratio Studiorum”. Every possible effort had been made to produce a practical system of education; theory and practice alike had been consulted, suggestions solicited from every part of the Catholic world, and all advisable modifications adopted. The Ratio Studiorum must be looked upon as the work not of individuals, but of the whole Society.” (https://www.newadvent.org/cathen/12654a.htm) Catholic Encyclopedia article on the Ratio Studiorum.
