The Graduate Gap Why b-grades in English are failing Sri Lanka’s STEM elite

“The issue is not the absence of English, but the way English is taught and used in higher education. Long exposure does not automatically lead to communicative confidence.”

“Engineering, science, and business are not simply content-heavy disciplines; they are professional domains with distinct ways of reasoning. Engineers justify decisions; scientists interpret data; business graduates persuade.”

“Employers did not highlight minor grammatical errors as major problems. Instead, they pointed to difficulties in explaining tasks, reporting work clearly, and communicating effectively.” 

Sri Lanka’s universities continue to produce world-class STEM and business talent, yet a quiet crisis is brewing within the lecture halls of its most prestigious institutions. While students spend a decade mastering the mechanics of the English language, they are entering the global workforce functionally silent. The problem, experts suggest, is not a lack of vocabulary, but a systemic failure to bridge the chasm between classroom grammar and the high-stakes world of professional communication. As the “missing link” in higher education becomes a national bottleneck, the call for a radical shift toward discipline-specific instruction is no longer just an academic debate—it is an economic necessity.

Sri Lanka prides itself on its strong higher education system, particularly in Science, Technology, Engineering, Mathematics (STEM) and Business Sciences. English plays a central role in this landscape as it is: the medium of instruction in most universities, the language of research, and the bridge to global opportunities. 

Yet persistent concern continues to surface across sectors. Many graduates, though academically capable, struggle to explain ideas clearly, write professional documents, or communicate confidently in academic and workplace settings.

This concern is often dismissed as a problem of “poor English.” However, research, both local and international, suggests that this diagnosis misses the point. The issue is not the absence of English, but the way English is taught and used in higher education.

Most Sri Lankan students encounter English for more than a decade before entering university. Yet studies conducted at Sri Lankan universities show that long exposure does not automatically lead to communicative confidence. A recent survey of undergraduates revealed wide variation in speaking ability, high levels of anxiety, and difficulty using English in real communicative situations, particularly when students were required to explain ideas or engage in spontaneous discussion (Chamba & Hansson, 2025). Many students demonstrated grammatical knowledge but hesitated when required to reason aloud or present ideas clearly.

This gap becomes especially visible at university level because higher education demands a different kind of language use. Engineering, science, and business are not simply content-heavy disciplines. They are professional domains with distinct ways of reasoning and communicating. Engineers justify design decisions. Scientists report and interpret data. Business graduates argue, negotiate, and persuade. In all these contexts, language is functional, purposeful, and tied closely to thinking.

Yet Sri Lankan research suggests that university English courses have not kept pace with these demands. An analysis of ESP teaching at the tertiary level shows that while universities recognize the importance of preparing students for professional environments, most still rely on general English syllabi (Dharmawardene & Wijewardene, 2022). These courses emphasize grammar, comprehension, and correctness, with limited attention to discipline-specific communication. As a result, students are often assessed on form rather than meaning.

Industry feedback reinforces this concern. A needs analysis published in the Sri Lanka Journal of Social Sciences reported that vocational and technical graduates frequently lack the specific English skills required in the workplace (Ranasuriya & Herath, 2020). 

Employers did not highlight pronunciation or minor grammatical errors as major problems. Instead, they pointed to difficulties in explaining tasks, reporting work clearly, and communicating effectively with colleagues and supervisors. The study concluded that existing English courses were poorly aligned with workplace realities.

Academic contexts reveal similar patterns. A needs analysis conducted at the University of Kelaniya found a clear mismatch between academic literacy instruction and disciplinary expectations, particularly in science-related fields (Pravini, 2024). Students struggled with structured writing, discipline-specific reading, and explanatory tasks. Lecturers noted that generic academic English courses did not adequately prepare students for the communicative demands of their disciplines.

These Sri Lankan findings mirror long-standing international research in English for Specific Purposes. Scholars in this field have consistently argued that language cannot be treated as a neutral, general skill. Foundational research by Dudley-Evans and St John (1998) showed that academic and professional communication is shaped by purpose, audience, and disciplinary convention. Ignoring these factors leads to teaching that is disconnected from real-world use.

More recent international studies tracking graduates into the workplace highlight the same issue. Research on business and engineering professionals shows that much of their daily work involves explaining decisions, writing reports, and negotiating meaning with diverse stakeholders (Chan, 2019; Chan, 2021). These are not skills developed through isolated grammar exercises. They require practice in authentic, context-specific communication.

In Sri Lanka, the consequences of this mismatch are increasingly visible. Engineering students may excel in technical problem-solving but struggle to articulate solutions. 

Business students may understand theories but falter when presenting arguments or writing reports. Assessment practices often reinforce surface learning by rewarding format and accuracy rather than clarity and reasoning. Over time, students learn to focus on what will be tested, not on how to communicate effectively. This is where English for Specific Purposes, or ESP, becomes relevant. ESP is not a new or narrow concept. It is a research-informed approach developed specifically to address the gap between general language teaching and professional communication. ESP begins with a simple premise: language instruction should be shaped by how language is used in specific academic and professional contexts.

Sri Lankan research provides evidence that such approaches are effective. An action research study with pre-university ESP learners demonstrated that task-supported, context-based instruction significantly improved speaking fluency and learner confidence (Gunarathne, 2025). Students engaged more actively when language tasks were linked to real purposes rather than abstract exercises. This aligns with international findings that relevance improves learning outcomes.

ESP classrooms differ from traditional English classes in important ways. Vocabulary is taught through use, not memorization. Writing is framed as problem-solving. Speaking activities mirror professional exchanges rather than classroom performances. Reading is treated as disciplinary inquiry. Assessment focuses on whether ideas are communicated clearly and appropriately, not merely on grammatical accuracy (Paltridge & Starfield, 2013).

For universities that lead in STEM and business education, these distinctions matter. Where academic and technical expectations are high, the limits of general English instruction become apparent early. Students are expected to explain, justify, and reason at a sophisticated level. When language instruction fails to support these demands, the problem lies not with the students, but with curriculum design. ESP does not replace disciplinary teaching. It strengthens disciplinary teaching by integrating language with thinking. Research shows that when communication is taught as part of disciplinary practice, students perform better academically and transition more smoothly into professional roles (Rafiq et al., 2024). Confidence develops not because English becomes perfect, but because it becomes purposeful.

The missing link in Sri Lanka’s universities, therefore, is not English itself. It is the failure to move from classroom English to professional communication. Addressing this gap does not require adding more courses, but rethinking how language is taught, assessed, and valued. Language must be recognized as a core academic and professional tool.

Acknowledging this gap is only the beginning. If the challenge confronting Sri Lanka’s universities is not a shortage of English, but a mismatch between how English is taught and how it is used in STEM and business professions, then more difficult questions follow. Why do general English models continue to dominate university curricula despite clear evidence of their limitations? How do current teaching and assessment practices shape student behaviour, often encouraging examination compliance rather than communicative clarity? 

And what practical alternatives exist within our own higher education system to address these concerns? These questions have direct implications for graduate employability, research quality, and national competitiveness. In the next article, these issues will be examined more closely, focusing on how English is currently taught and assessed in Sri Lanka’s universities and why meaningful reform has proven so difficult to achieve.
