Reimagining what we measure: How Al is challenging the tradition of language assessment
For decades, technology has reshaped "how" we measure language proficiency, from computer-based testing to Al systems that simulate human written or speech interaction. Yet the widespread use of generative Al does more than impact assessment methods; it exposes a mismatch between "what" traditional language assessments measure and "what" matters in real-world communication. Today, language users increasingly develop, edit and refine writing and speaking outputs with the help of Al, blurring the traditional boundaries of language proficiency.
In this talk, I argue that Al is not merely changing "how" we assess, but fundamentally challenging "what" we value as communicative competence. I will explore new, emerging dimensions of communicative competence that reflect how communication occurs in an Al-mediated world. I will also discuss key conceptual and practical challenges associated with giving language users access to generative Al tools during assessment and a potential path forward.
