'AI should assist teachers, not replace them': Union warns of AI marking risks
3 hours ago
- Secondary teachers are advised to retain control over marking student work, even when using AI tools.
- NZQA uses AI for marking NCEA co-requisite tests, achieving 80%+ agreement with human markers, reducing human check markers from 100 in 2024 to 34 in 2025.
- Automated marking is expected to expand by 2028–2030 under a new qualification, but critics argue it undermines teachers' professional learning and judgement.
- AI-human agreement on complex work is weaker than human-to-human, potentially inflating or compressing grades, making AI unsuitable for high-stakes summative assessments without human oversight.
- Some teachers support AI for saving time but insist humans must remain responsible for accuracy and accountability.
- The report recommends a hybrid model where AI assists but teachers retain control to maintain assessment credibility.
