The Assessment Crisis in the AI Era: Why Written Assignments Have Lost Their Meaning
When ChatGPT can produce a well-structured, logically sound academic paper in 30 seconds, the assessment value of traditional written assignments has nearly vanished. Chris Schaffer, a biomedical engineering professor at Cornell University, states bluntly: “You can’t pass an oral exam with AI.” He has introduced an “oral defense” system in his classes, requiring students to answer questions face-to-face with the instructor.
The core issue of this trend is not whether students cheat, but rather: How do we confirm what students have actually learned? Emily Hammer, associate professor of Middle Eastern languages and cultures at the University of Pennsylvania, observes that students are losing cognitive ability and creativity, a long-term concern from AI use.
| Assessment Method | AI Replaceability | Real Ability Verification | Teacher Burden | Student Stress |
|---|---|---|---|---|
| Traditional Written Report | Very High | Low | Low | Low |
| Class Discussion | Medium | Medium | Medium | Medium |
| Oral Defense | Low | High | High | High |
| Practical Exam | Medium | High | Medium | Medium |
| Closed-Book Written Exam | Low | High | Low | Medium |
Is the Return of Oral Exams an Educational Reform or a Forced Compromise?
This is not an ideal choice for educators but a necessary response. Bruce Lenthall, director of the Center for Teaching and Learning at the University of Pennsylvania, notes that the university is undergoing a “massive shift to in-person assessment”—including both written and oral forms. This Ivy League institution has begun hosting oral exam workshops for faculty to help design effective questions and grading criteria.
How Do Oral Exams Solve the AI Cheating Problem?
The core advantage of oral exams is immediacy and interactivity. When students cannot prepare for all possible questions in advance, instructors can probe, challenge, and guide based on responses, deeply exploring the depth of student understanding. This dynamic assessment makes AI assistance nearly impossible.
New York University offers an inspiring example: faculty there are increasing office hour requirements, random in-class call-ons, and impromptu presentations. One professor explains: “I need to look into students’ eyes and ask: ‘Do you really understand this material?’”
Who Will Benefit or Suffer from the Oral Exam Trend?
This trend will reshape the competitive landscape of the edtech market. Here are the main stakeholders:

Huihui Qi, an engineering professor at the University of California San Diego, has launched a three-year study on scaling oral exams during the pandemic, developing scalable oral assessment systems. Such research will directly lead to commercial products, including:
- AI-Assisted Oral Exam Platforms: Combining speech recognition and natural language processing to help instructors design questions and score in real time
- Oral Exam Simulation Tools: Allowing students to practice before formal exams
- Scoring Consistency Systems: Ensuring uniform grading standards across different instructors
Challenges for Traditional Assessment Industries
Standardized testing and online exam platforms will face greater pressure. When top universities begin questioning the value of written assignments, the core product positioning of these companies will be challenged.
Technical Challenges and Solutions for Scaling Oral Exams
The biggest obstacle to oral exams is time cost. An instructor can only conduct 3-5 oral exams per hour, while written assignments can be graded in batches of dozens. Here are solutions currently under development:

Deep Impact of Oral Exams on Student Learning Behavior
This is not just a change in assessment methods; it will fundamentally reshape students’ learning motivation and behavior patterns. When students know they must explain their thought process face-to-face, they will tend to:
- Deep Understanding Rather Than Surface Memorization: Oral exams require real-time reasoning and argumentation
- Active Learning: Cannot rely on passive reading or AI summaries
- Improved Communication Skills: Oral expression becomes a required skill
Special Challenges for Gen Z
Gen Z, the “stare generation” raised in digital environments, is accustomed to anonymous interactions behind screens. Oral exams require them to face instructors directly, which is a significant psychological stress for many. But this is exactly what educators hope to achieve—breaking the protective layer of screens and returning to genuine human interaction.
How Should Taiwan’s Education System Respond?
Taiwan’s universities are significantly lagging in adopting oral exams. Currently, only top universities like National Taiwan University and National Tsing Hua University have piloted oral exams in small classes, with overall adoption far below that of the US. Given the similarly high usage of AI tools among Taiwanese students, this is a trend that must be addressed.
Recommended Priority Strategies
- Teacher Training: Offer oral exam design workshops to help instructors master effective questioning techniques
- Technology Investment: Evaluate AI-assisted oral exam platforms to lower the barrier to scaling
- Course Design: Combine oral exams with written assignments and practical assessments to form a diverse assessment system
- Student Communication: Clearly explain the purpose and grading criteria of oral exams to reduce anxiety
Business Implications of the Oral Exam Trend for the EdTech Market
This trend will spawn at least three new edtech submarkets:
1. AI Oral Exam Scoring Platforms
Estimated market size of $1.2 billion by 2027, with major players including existing edtech giants and voice AI startups.
2. Oral Exam Simulation and Training Tools
Similar to existing interview simulation tools but focused on academic oral exam scenarios.
3. Teacher Assessment Design Consulting Services
Providing customized assessment reform solutions for universities.
FAQ
Why are US universities starting to adopt oral exams on a large scale?
Because generative AI makes it difficult to discern students’ true abilities from written assignments, and oral exams directly verify whether students genuinely understand and master the material.
What impact does the return of oral exams have on the edtech industry?
It will spur AI-assisted oral exam platforms, speech recognition scoring systems, and real-time feedback tools, creating a new edtech submarket.
Which universities have already implemented oral exam systems?
Cornell University, University of Pennsylvania, New York University, and University of California San Diego have introduced or researched oral exam assessments.
Will oral exams completely replace written assignments?
No, oral exams will coexist with written assignments as complementary assessment mechanisms, especially in disciplines requiring deep thinking.
Are universities in Taiwan following the oral exam trend?
Some top universities like National Taiwan University and National Tsing Hua University have piloted oral exams in small classes, but overall adoption remains far behind the US.
