Despite tremendous progress in education and workforce participation, many talented women in science, technology, engineering, and mathematics (STEM) remain stuck—unable to break through to leadership, recognition, and influence. If you are a woman in STEM or you care about gender equity, you have likely noticed this phenomenon. The question is: what is holding women back, and how can we change the story?
This blog post looks at three major reasons why women in STEM do not advance as much as they should. These reasons have been identified in global research and in the lived experience of women across continents, including Africa. You will also find practical steps that organizations and individuals can take to address these barriers, along with answers to common questions.
The Paradox of Progress
More girls and young women than ever before are enrolling in science and technology courses. They are excelling in classrooms and entering the workforce in greater numbers. Yet, a closer look at the statistics reveals a troubling reality: women are present at entry level, but their numbers drop off dramatically in senior positions, leadership roles, and boardrooms.
You might see women leading their labs, teaching classes, or contributing to breakthrough projects. However, when it comes to being promoted, recognized, and given the power to shape the future, women remain underrepresented.
Today’s challenge goes beyond “getting into STEM” and includes getting promoted, being visible, and making real impacts. Understanding why this happens is the first step toward building a more equitable and innovative STEM community.
A Brief History: Women in STEM
For centuries, women made vital contributions to science and technology, often without credit or recognition. From Ada Lovelace’s pioneering work in computer science to Katherine Johnson’s mathematical genius at NASA, women have always been present, but their names and achievements were often hidden or attributed to men.
In the 20th century, legal changes and social movements opened more doors. Women began to earn degrees in chemistry, engineering, mathematics, and related fields. By the 21st century, women were present in most university classrooms and STEM workplaces.
Despite this progress, the journey from “getting in” to “rising up” remains difficult for many women. The historical exclusion of women from decision-making roles has created a culture and structure that still affects advancement today.
The Pipeline Myth and Where Women Stall
Many companies and institutions claim that the reason for few women in leadership is a “pipeline problem”: the belief that there are not enough qualified women entering STEM. This explanation is misleading and incomplete.
Research shows that the pipeline is not empty. According to a 2023 McKinsey & Company report, women make up nearly 50% of entry-level roles in some STEM fields, but less than 20% of senior leadership. In engineering and computer science, the numbers are even lower.
The challenge is not just about getting women into STEM, but helping them advance, lead, and be visible at every level.
1. Leadership Barriers and the Glass Ceiling
One of the most significant reasons women in STEM do not advance is the existence of leadership barriers, often described as the “glass ceiling”. This is an invisible, yet powerful, set of obstacles that prevents women from reaching the highest levels of leadership.
What Does the Glass Ceiling Look Like?
- Stalled Promotions: Women find themselves stuck in the same roles for years, even when their performance is outstanding. They are often passed over for leadership opportunities in favor of men with similar or even less experience.
- Limited Access to Key Projects: In many organizations, the most visible and high-impact projects become stepping stones to the next level. Women are less likely to be assigned to these projects, which makes it harder for them to prove their readiness for advancement.
- Unconscious Bias: Decision-makers, often unintentionally, may see men as natural leaders. Stereotypes about what a leader “should” look like can influence who gets promoted and who gets overlooked.
- Lack of Sponsorship: Research shows that women often have mentors but lack sponsors. A sponsor is a senior leader who actively advocates for your promotion, recommends you for important assignments, and uses their influence to move your career forward. Without sponsors, women’s progress can stall.
The “Sticky Floor” Effect
While the glass ceiling stops women from rising, the “sticky floor” keeps them in roles that are less likely to lead to advancement, such as support functions or lower-paid positions. This means fewer opportunities to gain the experience and visibility needed to climb higher.
Why Leadership Barriers Matter
Leadership is where decisions are made about products, policies, and people. When women are not in these rooms, their ideas, perspectives, and priorities are missing from decisions that affect everyone.
Women in STEM deserve equal access to leadership, not just for fairness, but for better science, technology, and innovation.
2. Lack of Visibility and Recognition
Another major barrier to advancement is the lack of visibility and recognition for women’s contributions. In STEM, being recognized for your work is crucial for promotions, funding, and invitations to participate in influential projects.
How Invisibility Happens
- Ideas Ignored: Women often report that their ideas are dismissed in meetings, only to be accepted when repeated by a male colleague. This not only discourages women, but also makes it harder for them to build a reputation as innovators or problem-solvers.
- Credit Stealing: Research has shown that women’s achievements are more likely to be credited to others, and men’s contributions are often more visible in team settings. This is sometimes called the “Matilda effect”.
- Few Awards or Public Recognition: When it comes to awards, speaking opportunities, or media coverage, men are still far more likely to be highlighted. This reinforces the perception that men are the leaders and innovators in STEM.
- “Office Housework”: Women are more likely to be asked to take on tasks that are necessary but undervalued, such as organizing events, mentoring new hires, or taking notes in meetings. While these tasks are important, they are rarely rewarded with promotions or public recognition.
The Cost of Invisibility
In STEM fields, visibility is often the currency for advancement. If your work is not seen, it is less likely to be rewarded. This can mean missing out on funding, leadership roles, or invitations to participate in key projects.
When women’s contributions are overlooked, entire organizations miss out on valuable ideas and innovations. The lack of recognition also discourages women from staying in the field.
3. Ineffective Reviews and Biased Advancement
Performance reviews and promotion processes are intended to be fair and objective, but in reality, they are often influenced by personal judgments and unconscious bias.
Common Patterns of Bias
- Subjective Criteria: Women are often judged on how “likable” or “collaborative” they are, while men are judged on measurable results and leadership potential. This means men are more likely to be recognized for ambition, while women are penalized for being “too assertive” or “not assertive enough”.
- Vague Feedback: Research shows that women are less likely to receive specific, actionable feedback. Instead, they are told to “keep up the good work” or “work on your confidence”, while men are given clear guidance on how to reach the next level.
- Promotion Readiness: Women are frequently told they need more experience before being promoted, while men are encouraged to take risks and “grow into the role”. This slows women’s progress and erodes their confidence.
- Overlooked Achievements: Sometimes, the impact of women’s work is downplayed or attributed to the team rather than the individual, making it harder to demonstrate readiness for a higher role.
The Impact of Biased Reviews
Over time, these patterns add up to significant gaps in advancement. Talented women watch as less qualified men move ahead. Some women become frustrated and leave the field entirely, while others stay but feel stuck under a glass ceiling.
Intersectionality and Added Hurdles
It is important to recognize that not all women face the same barriers. Women’s experiences in STEM are shaped by many factors, including race, ethnicity, nationality, sexuality, disability, and more. For example, African women in STEM often face unique hurdles:
- Cultural Expectations: In some societies, women are expected to prioritize family or community roles over careers, making it more difficult to pursue demanding STEM paths.
- Lack of Role Models and Networks: Access to mentors, sponsors, and professional communities can be limited for women of color or those from underrepresented backgrounds.
- Double Bias: Women who are also part of racial or ethnic minorities may experience both gender and racial bias, sometimes called “double jeopardy”.
- Geographical Barriers: Women in some regions face additional challenges such as lack of resources, limited access to technology, or societal stigma about women in technical fields.
Intersectionality means that solutions must be tailored. What works for some women may not work for all. Recognizing and addressing these layered barriers is essential for real progress.
The Cost of Inaction
When women are held back in STEM, everyone pays the price.
- Missed Innovation: Diverse teams are more creative and solve problems more effectively. Excluding women limits the range of ideas and solutions.
- Loss of Talent: When women leave STEM, organizations lose skilled professionals who could contribute to growth and progress. This is especially costly in fields facing skills shortages.
- Reinforcing Inequality: When women are not seen and heard in STEM, stereotypes persist and a new generation is discouraged from pursuing these careers.
Inaction is not neutral, it perpetuates inequality and limits everyone’s potential.
What Works: Solutions for Real Change
The good news is that change is possible. Many organizations and advocacy groups are making progress by taking concrete actions. Here are strategies backed by research and real-world results:
1. Transparent and Fair Promotion Processes
- Define clear criteria for advancement and make them publicly available.
- Use diverse panels for hiring and promotion decisions.
- Regularly audit promotion data for gender and racial disparities.
