In 1956, Sra. Poventud de Rodriguez established a small scholar building in her home to kids at her neighborhood, in Guaynabo. Instantly, more admissions for entry were received. After that, Rodriguez united forces with Sra. Acosta de Lao in 1968 and both rented a bigger building near the previous position, in Guaynabo. From there, it was established the year right before kindergarten (Pre-K) and Rosa-Bell with a start of about 230 students. Both directors decided to start a new adventure and, by kids parents' choice, begin elementary school. First grade started in 1970–1971. Because of great success, the directors decided to add a grade to the school every year, accredited by the Department of Public Instruction of Puerto Rico (DIPP). Finally, the school finished its high school in the academic year 1981–1982. The public registration increased, and they were forced to find new facilities. In 1974, they relocated to a new building, still closer to the previous spot, in the same city it is now. Since then, more facilities have been added, buildings have been remolded and improved, and better services with more classrooms have been presented.

Rosa Bell has a set of varied elective classes (dance, photography, sketchbook, theater, French, German, Italian, engineering, marketing, home economics, physical education, art, chemistry, biology, environmental sciences, and many more).
