The Lasallians had settled in Brazil in 1907 in response to requests from the bishop of Rio Grande do Sul, Dom Claudio Ponce de Leão, and the Belgian priest Joseph Martin Moreau.
According to Vanessa Lazzaron the Brothers had conflicts with the parish, especially during the administration of Canon João Meneguzzi, due to disagreements about educational philosophy and issues related to the rent and financing of the construction of the new school, perpetuating a climate of animosity between the institutions for many years.
Land was bought in front of the previous premises, and construction was organized by the Brother Mauricio and a special commission that had Canon Meneguzzi and the municipal intendant Celeste Gobbato as honorary presidents.
[5] At this time, the school offered an education in three sections: According to Lazzaron, Canon Meneguzzi only came to support the brothers after being convinced of the project, leading to an end to the disputes.
In addition to classrooms and administration rooms, the building included a chapel, living quarters for the brothers, a kitchen, dining hall, infirmary, laboratories, a large patio, and sports facilities.
[2] In the pediment, a statue of Our Lady of Mount Carmel was installed, and in the balcony, a sculptural group depicted Saint Jean-Baptiste de La Salle pointing to the sky, surrounded by five boys who symbolize the youth of the five continents.
In 1932 the first class of baccalaureates graduated, and the institution was officially converted into the Ginásio Municipal Nossa Senhora do Carmo, with a complete five-year secondary course and a boarding school; Brother Fidel was the director.
In 1966, the vocal group Os Canarinhos do Carmo appeared, making its presence felt on stages of festivals and shows in several states of Brazil for more than 20 years.
Notable former pupils include governors Euclides Triches and Pedro Simon, ministers Mário Andreazza and Higino Corsetti, and Senator José Paulo Bisol, and many technicians.
[9][2] In the opinion of writer Nilson Luiz May, in Caxias "the Lasallian brothers formed generations of students with extremely solid cultural bases".
[14] Extra-curricular activities include the Reader's Club, poetry, architecture, painting and art workshops, ballet, English, taekwondo, robotics, theater, futsal, music and swimming schools.
There are partnerships with other institutions for technical and vocational courses such as Accounting, Job Security, Real Estate Services, Logistics, Information Technology, Management, Financial Sector, Sales and Human Resources.
