In 1931, the school was placed under the control of the University of Buenos Aires (UBA), and in 1953 women were given the right to study in the institution.

This relationship between the school and the University also gives graduated students the possibility of attending an extra 6th year for a degree in Ciencias Comerciales (Bachelor in Commercial Science); the subjects for this academic year are equivalent to the UBA's Ciclo Básico Común (CBC - Common Basic Cycle; a year of basic subjects study, mainly aimed to level students from different high school backgrounds) plus four other assignments.

This extra curricular year entitles the students to enter the UBA in many majors, specially including economy-related ones, without the need of attending the CBC.

These students are subject to 12 exams divided into four major areas: Mathematics, History, Geography and Spanish.

The Student Center, usually referred to as CECaP, holds annual elections and, until the year 2005, was subdivided in different areas, such as Sports, Charity Action, Press and Culture; since 2006, though, it's divided in Comisiones (commissions) created by the students, under the supervision of the Comisión de delegados (Delegates commission) This system is more democratic than the old system, since the commissions now are created by and their membership determined by students, whereas previously they were managed by the political parties.
