When in 1931 football became professional in Argentina, Estudiantil Porteño joined the "Asociación Amateurs Argentina de Football", a rival league that remained amateur. The club won the 1931 (defeating Almagro 3-1 at the final) and 1934 (played in a round-robin format) titles, just before the AAF merged with professional Liga Argentina de Football and all the AAF teams were therefore relegated to the second division.
Estudiantil Porteño played at the second division (current Primera B Metropolitana) only 4 seasons, disaffiliating from the Association at the end of the 1938 tournament. Since then, the club has not played any official football championship again.
Today many sports can be practised at the club, which has competitive teams in basketball, roller hockey and handball.
