Perhaps the greatest intuition of Calasanz was to declare that education should be compulsory and tuition free for everyone, that it should atart from infancy, that individual attention could be given in group instruction, that students could move up from one level to another, and taht parents could also receive help from the school through children.

Calasanz made many significant contributions to the field of education. He founded, organized and systematized a method of educationg primary schools pupils through progressive levels, a system of vocational training, and a system of public secondary education. There could be as many as 1,500 students in one of his schools, making them very different from the other local schools which usually had only one teacher. Here are some quatitions from Calasanz,

"Be outspoken so that the deputy might command the constables not to allow students to be idle around the city but that they should either go to schools or to work. I speak, naturally, about the poor. Rich people will not allow their children to roam around. Encourage Fr. Juan Bautista to be deligent and to adapt himself to the capability of the students, not only in teaching the vernacular language texts, but also in expaining the lessons.

After the initial exam, put the new students in the most suitable grade and with the most suitable teacher. They should pass an examination at least twice a year, and the most capable should got o the next higher grade."
