Example: Duolingo English Test (DET) — an online, AI-powered language proficiency exam.

How it works:

Students complete a series of adaptive tasks in reading, listening, writing, and speaking.

The test adjusts difficulty in real time based on responses.

AI evaluates pronunciation, fluency, grammar, and text quality.

Human reviewers verify recorded speaking and testing behavior for fairness.

Strengths

Highly accessible: Can be taken at home — no need to travel to testing centers.

Inclusive: Cheaper than traditional tests like TOEFL/IELTS.

Adaptive and efficient: Test lasts ~45–60 minutes; results in 2 days.

Authentic tasks: Speaking and writing integrated into real scenarios.

Weaknesses

Technology dependence: Students need a strong device and internet — a disadvantage in low-resource areas.

AI limitations: Automated scoring might misjudge accents or creative language use.

Security concerns: Remote testing raises questions about fairness and identity validation.

Humanized Insight

I love how this test makes opportunities — like studying abroad — more reachable for students who can’t afford expensive standardized exams. But I also believe we need a balance: digital tools should help students show their strengths without ignoring the cultural, emotional, and human parts of learning.

Assessments can evolve — as long as we remember there is a real learner behind every data point
