Why understanding your language proficiency may be one of the smartest investments you make in your career
Growing up, my heritage language was simply part of everyday life. As a first-generation Puerto Rican, Spanish was the language of family gatherings, traditions, stories, and connection. Like many heritage speakers, I never questioned whether speaking another language had value; it simply existed as part of who I was.
What I didn’t fully appreciate at the time was that my heritage language wasn’t just shaping my cultural identity; it was becoming one of my most valuable professional assets.
Throughout my career, Spanish has been interwoven in my work, whether that involved interpreting medical documents for the physicians I worked with or translating for patients in the healthcare setting. Today, it continues to serve me as I work with colleagues and vendors across Spanish-speaking continents.
Organizations in various industries operate across both visible and invisible borders, serving increasingly diverse communities in a competitive global economy where communication extends beyond simply speaking another language. Employers need professionals who can build trust across cultures, navigate multicultural environments, and strengthen relationships with clients, partners, and colleagues around the world.
However, many heritage speakers continue to underestimate the value of the language they’ve carried with them since childhood.
Why? It could be for a variety of reasons.
Maybe because it feels ordinary and they don’t feel their workplace needs a bilingual speaker.
Maybe it’s because they compare themselves to native speakers from another country.
Or perhaps they simply haven’t considered that the language spoken around the dinner table could become a competitive advantage in the workplace.
What if one of your greatest professional assets has been hiding in plain sight?
Heritage Language Is More Than Cultural Identity
For many bilingual speakers, heritage language represents family history, community, and belonging. Research consistently shows that maintaining a heritage language strengthens cultural identity, reinforces family connections, and enhances intercultural competence. Studies by Diskin (2020), Liang (2021), Stavans (2020), and others demonstrate that heritage language maintenance contributes to both personal identity and social belonging.
Increasingly, however, researchers are recognizing another dimension of heritage language:
It is also human capital.
Rather than viewing bilingualism solely through a cultural lens, researchers now describe heritage language as a valuable resource that contributes to economic mobility, workforce readiness, entrepreneurship, and international engagement. Heritage language provides individuals with the ability to bridge cultures, communicate authentically with diverse populations, and navigate environments where cultural understanding is just as important as technical expertise.
In other words, your heritage language tells the story of where you come from, but it can also help shape where you’re going.
The Marketplace Has Changed
Not long ago, bilingualism was often associated primarily with translation, interpretation, or customer service positions.
Today’s employees tell a different story.
Organizations increasingly recognize that language proficiency supports functions across nearly every department, including sales, marketing, healthcare, human resources, education, government, compliance, international business, vendor management, consulting, workforce development, and executive leadership.
Research suggests that language skills become especially valuable when paired with customer-facing, commercial, and relationship-building competencies (Damari, 2017; Pietrzyk-Kowalec, 2023). Language is no longer simply just communication; it has become a strategic business capability.
Professionals who can communicate across cultures often strengthen client relationships, improve collaboration, reduce misunderstandings, and help organizations expand into new markets.
For entrepreneurs, bilingualism can create opportunities to serve broader audiences, build stronger community relationships, and differentiate themselves in increasingly competitive industries.
My question to you is, are you leveraging your heritage language?
If so, how?
Your Language Is Not Static
One of the biggest misconceptions about bilingualism is that once you become bilingual, your proficiency remains unchanged throughout your life.
The reality is much more dynamic.
Like any professional skill, language evolves through use.
Some heritage speakers develop exceptional conversational fluency but rarely practice professional writing.
Others maintain excellent listening comprehension while speaking less frequently over time.
Some expand their vocabulary through higher education or professional experience, while others notice that certain words become harder to recall after years of using English almost exclusively.
Researchers describe this natural process as language attrition—the gradual change in language proficiency that occurs when a language is used less frequently. Fortunately, language development works in both directions. Skills can decline through disuse, but they can also be strengthened through intentional practice, continued learning, professional application, reading, travel, and immersion.
Language proficiency isn’t fixed; it’s lifelong.
Encouraging, isn’t it?
Every conversation, every book, every professional interaction, and every opportunity to use your heritage language becomes an investment in your future capability.
You Can’t Leverage What You Haven’t Measured
As professionals, we routinely assess our skills throughout our careers. We pursue certifications, complete continuing education, and earn licenses. To advance in our careers, we measure progress in countless ways.
Yet many heritage speakers have never formally assessed one of their most valuable professional skills.
A language assessment isn’t about proving your worth.
It’s about understanding your proficiencies and building from there.
Understanding your current proficiency can help you identify strengths, recognize opportunities for continued growth, communicate your abilities more confidently, and make informed decisions about career advancement.
It also provides an objective benchmark that employers, educational institutions, and professional organizations can recognize.
Just as financial planning begins by understanding your current financial position, career planning begins by understanding the skills you already possess.
An Investment That Appreciates Over Time
Degrees prepare us for careers, certifications validate specialized knowledge, and leadership development strengthens management skills.
Heritage language deserves to be viewed through the same lens.
Unlike many professional skills that require periodic renewal, language has the potential to appreciate over a lifetime when intentionally maintained and continuously developed.
Every new professional experience expands vocabulary.
Every meaningful conversation strengthens fluency.
Every opportunity to read, write, teach, mentor, or collaborate deepens communication skills.
Maintaining your heritage language isn’t simply preserving your past.
It’s investing in your future.
Looking Back
Looking back on my own career, I can clearly see how bilingualism opened doors I never anticipated.
As a heritage Spanish speaker, I initially viewed my language as something deeply personal, a connection to family, culture, and identity. Over time, however, I realized it had become much more than that. It helped me to build stronger professional relationships, communicate more effectively with diverse audiences, and recognize opportunities that may have otherwise gone unnoticed.
The language I inherited became part of the professional I was becoming.
I am grateful to my parents for helping me shape my views. I was encouraged early on that being bilingual was a gift and that it should never be taken for granted.
Your Heritage Language Is an Investment Worth Understanding
Around the world, organizations of all sizes and industries are recognizing the value of multilingual professionals. At the same time, research continues to demonstrate that heritage language contributes to economic opportunity, intercultural competence, workforce mobility, and entrepreneurial success. The challenge is no longer convincing employers that language matters. Increasingly, it’s helping heritage speakers recognize the value of the skills they already possess.
Your heritage language is part of your cultural identity. Let it become your professional identity as well.
Like every valuable professional skill, it deserves to be understood, maintained, and intentionally developed.
A professional language assessment is just the beginning. When you’re provided a clear understanding of your current proficiency, you’ll identify opportunities for continued growth.
Confidently communicate one of your greatest strengths in an increasingly interconnected world. After all, you can’t fully leverage an asset until you understand its true value.
