Inspiring, Retaining and Promoting Female Talent in STEM Careers


International Day of Women and Girls in Science strives to highlight the disparities facing women and girls as they seek both education and careers in STEM fields, and to both broaden participation and create full and equal access to STEM for women and girls. The National Radio Astronomy Observatory (NRAO) team in Chile launched PROVOCA—PROmote + VOCations) in 2019, and is bringing together mentors and students in STEM to bridge the gap. Paulina Bocaz, AUI Representative and NRAO Assistant Director for Chile, details the challenges faced in building strong foundations for women in STEM and the achievements of PROVOCA in Chile.

Retaining and promoting female talent in science, technology, engineering, and mathematics (STEM) is a goal that must be embraced by large scientific facilities, civil society, academia, and the private sector. A STEM career can be long and full of obstacles for underrepresented minorities, including women, who are strongly influenced by family expectations, teacher bias, and work environments plagued by stereotypes. More female role models in STEM are needed to inspire and increase women’s participation, and they are currently insufficient to retain female employees and stimulate their professional growth into leadership positions.

Let’s take the Chilean case. The exceptional conditions of the Atacama Desert sky have attracted some of the largest and most advanced astronomical projects, including NSF-funded big facilities such as the Atacama Large Millimeter/submillimeter Array (ALMA), managed by AUI/NRAO in representation of North America. In the next decade, Chile will concentrate up to 70% of the world’s capabilities to observe the heavens.

This natural competitive advantage has surely inspired girls to choose astronomy and other STEM careers in Chile? Paradoxically the answer is no. According to a 2020 study by UN Women, among 18 countries in Latin America and the Caribbean, Chile has the lowest percentage of women with an academic degree in information and communication technologies (12.7%); ranks third lowest in engineering, manufacturing, and construction (17.7%); and fourth lowest in natural sciences, mathematics and statistics (46.5%). This discouraging reality is counterintuitive when one considers Chile’s high levels of economic and human development in Latin America and is compounded by a leaky pipeline of talent. As R&D careers advance, moving from assistant positions to full professorship to the leadership of departments and universities, there are fewer and fewer women, a situation that has come under scrutiny but changes slowly.

As part of AUI/NRAO’s mission to broaden participation and have a positive societal impact, we leverage big facilities as a unique platform to do this. In 2019 we launched PROVOCA, a communications campaign to raise the visibility of female STEM professionals and girls who aspire to follow one of these careers. PROVOCA is an acronym (PROmote + VOCAtions) and wordplay to foster STEM careers, but also to provoke cultural changes. The PROVOCA campaign was recognized by the National Science Foundation STEM for All Video Showcase with a Public Choice Award in 2021.

The communications campaign was successful and far-reaching, but we soon realized that inspiration is not enough to retain and stimulate professional growth. To accomplish this, it is necessary to guide and support girls and young women throughout their STEM journeys. The PROVOCA mentorship program and network take on this challenge, involving female STEM professionals and students in a long-term commitment. Training spanned ten months (May to December 2021) and comprised 350 hours of lectures, coaching sessions, networking meetings, roundtable discussions, and final projects that each participant presented in front of their peers. Theoretical and practical lessons helped develop skills that are key to mentoring, including active listening, interpersonal relations, communications, and leadership. Although the primary focus was on preparing mentors to guide students, the experience had a profound impact on the mentors themselves. As research into the most effective ways to retain underrepresented minorities in STEM attests, and as feedback from PROVOCA mentors confirmed, a network of professional peers is crucial to the affirmation of their own STEM identity, as well as the support of the next generation of STEM professionals. A total of 28 women completed their training and were certified as PROVOCA mentors in December 2021.

Now that the PROVOCA mentors’ network is a reality, the next goal is to introduce them to the community, so that high school girls and college women from all over the country can get to know them and find the support they need to pursue a STEM career. In April 2022, AUI/NRAO will open an application process for students who are interested in a PROVOCA mentorship ( We expect the power of this network to be exponential, recruiting and training new mentors among students in years to come, and encouraging other organizations to replicate the experience.
