🌐 Adoption of AI Grading Across Singapore's Leading Universities
Singapore's higher education landscape is rapidly evolving with the integration of artificial intelligence (AI) tools for grading student assessments. The National University of Singapore (NUS), Nanyang Technological University (NTU), Singapore University of Technology and Design (SUTD), and Singapore Institute of Technology (SIT) have pioneered this approach, allowing lecturers to leverage AI for preliminary grading while mandating human review for final decisions. This hybrid model addresses longstanding challenges in assessment scalability amid growing class sizes and diverse student needs. Launched primarily between 2024 and 2025, these practices reflect Singapore's forward-thinking education policies, emphasizing technology to enhance efficiency without compromising quality.
AI grading, also known as automated assessment, involves machine learning algorithms analyzing student submissions—such as essays, exams, or code—for content accuracy, structure, and language proficiency. In Singapore universities, these tools process handwritten or digital responses, grouping similar answers and suggesting scores aligned with predefined rubrics. The step-by-step process typically includes: uploading submissions, AI pattern recognition, preliminary scoring, and lecturer verification. This not only speeds up workflows but also promotes consistency, as human graders can vary due to fatigue or subjectivity.
For those exploring careers in higher education, platforms like higher-ed-jobs offer opportunities in edtech integration and lecturing roles at these institutions.
Pioneering at NUS: Validated Tools for English Proficiency
At NUS, AI grading debuted in July 2025 for two post-admission English tests targeting students needing language enhancement. The unnamed tool, rigorously validated against expert human graders, evaluates argumentative essays on content, organization, and language use. It runs dual assessments per submission, with human auditors reviewing all results and borderline cases to ensure reliability. Associate Provost Melvin Yap highlighted how this hybrid method boosts consistency over pure human grading, mitigating fatigue-related variances.
This implementation aligns with NUS's broader AI strategy, including ScholAIstic for law role-playing simulations. Lecturers must secure department head or dean approval, underscoring a cautious rollout. Students are notified upfront, fostering transparency. Early observations indicate enhanced grading equity, particularly for large cohorts where manual review is resource-intensive.
NTU's STEM Focus: Streamlining Physics and Math Exams
NTU led the charge in August 2024, permitting AI for midterm and final exams in select physics and mathematics modules. Tools like Gradescope scan handwritten answers, cluster similars, and enable batch human adjustments. Deputy President Christian Wolfrum noted improvements in consistency and efficiency, with instructors retaining ultimate authority.
The process involves AI initial scoring followed by lecturer overrides, ideal for technical subjects with objective rubrics. NTU's chatbots, such as Prof Leodar, complement this by aiding preparation, though studies reveal better surface-level outputs but potential gaps in deep comprehension. Aspiring lecturers can find relevant positions via lecturer-jobs.
SUTD: Gradescope Revolutionizes CS and Design Assessments
SUTD adopted Gradescope in April 2025 for computer science and design school tests featuring short-answer and explanation questions. Associate Provost Ashraf Kassim described AI as a 'supporting partner,' grouping responses for efficient human review. This suits SUTD's project-based learning, where quick feedback accelerates iteration.
In first-year Design Thinking courses, students access AI for rubric feedback on posters, with faculty finalizing grades. Dr Jason Lim emphasized reciprocity—AI aids but doesn't replace human effort. This model scales personalized insights in multidisciplinary environments.
SIT's AI-Orate: Chatbot-Driven Adaptive Quizzing
SIT trialed AI-Orate in October 2025 with 50 food technology students, using chatbots to quiz on industrial machine programming and probe reasoning. Associate Professor Wong Shin Yee reported slashing assessment time from a week to two days, enabling customizable large-class evaluations. Deputy Director Karin Avnit praised adaptive follow-ups for true competence demonstration.
Transcripts and recommended grades feed into human review, offering 'second chances' via prompts—unlike rigid tests. Student Lief Chng appreciated nuance capture. SIT's radiography studies further blend AI-human co-marking for video role-plays.SIT AI co-marking research
Human Oversight: The Safeguard in AI Grading Practices
Across NUS, NTU, SUTD, and SIT, policies mandate teacher review of AI outputs and student notification for graded assessments. This mitigates risks like algorithmic bias or misinterpretation. NUS's double-AI plus audit exemplifies rigor; NTU/SUTD batch reviews streamline without abdicating responsibility. Students can appeal, ensuring accountability.

Key Benefits: Efficiency, Consistency, and Innovation
- Time Savings: SIT's chatbot halves assessment duration; Gradescope accelerates batch processing.
- Consistency: Reduces human variability, as per NUS observations.
- Scalability: Handles large/group submissions adaptively.
- Enhanced Feedback: Adaptive probing reveals deeper understanding.
Assoc Prof Ben Leong (NUS) predicts AI surpassing human accuracy in five years, freeing educators for mentorship.
CNA on AI in teachingChallenges: Addressing Accuracy, Bias, and Equity Concerns
Critics highlight AI's limitations in nuance, especially subjective essays. SMU's Venky Shankararaman stresses human judgment for high-stakes tasks. Students like Leslie De Souza (NUS) worry about improvement guidance; Ryanna Lee (NTU) calls for oversight. No Singapore-specific accuracy stats exist, but global studies note 80-90% alignment in STEM, lower in humanities. Bias risks from training data persist, prompting validation protocols.
Voices from the Ground: Lecturers and Students Speak
Lecturers value bandwidth for meaningful interactions (Dr Rebecca Tan, NUS). Students mixed: acceptance for prep, skepticism for grading (Ms Sophia, NUS: 'slap in the face'). CNA survey of 10 profs: near-universal use, but ethical transparency key.
