Although her formal education had ended by 1900, she was able to get work as a teacher thanks to her older sister, Emelina, who had likewise begun as a teacher's aide and was responsible for much of the poet's early education. The poet was able to rise from one post to another because of her publications in local and national newspapers and magazines. Her willingness to move was also a factor. Between the years 1906 and 1912 she had taught, successively, in three schools near La Serena, then in Barrancas, then Traiguén in 1910, and in Antofagasta in the desert north, in 1911. By 1912 she had moved to work in a liceo, or high school, in Los Andes, where she stayed for six years and often visited Santiago. In 1918 Pedro Aguirre Cerda, then Minister of Education and a future president of Chile, promoted her appointment to direct a liceo in Punta Arenas. She moved on to Temuco in 1920, then to Santiago, where in 1921, she defeated a candidate connected with the Radical Party, Josefina Dey del Castillo, to be named director of Santiago's Liceo #6, the country's newest and most prestigious girls' school. Controversies over the nomination of Gabriela Mistral to the highly coveted post in Santiago were among the factors that made her decide to accept an invitation to work in Mexico in 1922, with that country's Minister of Education, José Vasconcelos. He had her join in the nation's plan to reform libraries and schools, to start a national education system. That year she published Desolación in New York, which further promoted the international acclaim she had already been receiving thanks to her journalism and public speaking. A year later she published Lecturas para Mujeres (Readings for Women), a text in prose and verse that celebrates Latin America from the broad, Americanist perspective developed in the wake of the Mexican Revolution.
