Her father gave her and her sisters a traditional education and home tutoring provided by a family friend, the Sheikh Manachou.

After hearing a discussion between nationalist leaders on the dire situation of the country, attended notably by Mahmoud El Materi, Bchira Ben Mrad had the idea of creating a framework for women to be active in the national movement.

In 1936, Ali Belhouane and other activists unsuccessfully organized a fair to raise money for North African students settled in France. Ben Mrad then decided to organize with women. She obtained the agreement of nationalist leaders Belhouane and Mongi Slim, initially skeptical, and created an organizing committee of Naima Ben Salah, Tewhida Ben Sheikh (the first woman physician in Tunisia), the Hajjaji girls (whose father is a minister), Hassiba Ghileb (granddaughter of Cheikh El Medina Sadok Ghileb) and Ben Miled Nebiha (wife of Ahmed Ben Miled): they managed to gather 9000 people in Dar El Fourati, remained a bourgeois family traders, and collected a significant amount of money given to nationalist leaders.
A week later, in May 1936, she founded the UMFT, constituting the first Tunisian women"s organization.
The UMFT worked with the Neo Destour. Other women joined the UMFT as activists like Moufida Bourguiba, Wassila Ben Ammar, Radhia Haddad, and Fethia Mzali.
