Subclaims¶

q2 i? Education-specific defenses outperform general-purpose defenses, with taxonomy-augmented classifiers SG+T (-30.1 pp), GOS+T (-25.6 pp), and LG3+T (-22.2 pp) achieving the largest ASR reductions. → Park 2026

Park, J., Han, J., Yoo, H., Ahn, S.-Y., Yoon, J., & Oh, A. (2026). EduZone: A Framework for Evaluating LLM Safety for K-12 Students and Teachers. arXiv preprint. https://arxiv.org/abs/2608.02024 doi:10.48550/arxiv.2608.02024

q2 · i? · design · r2

Defense experiment on a stratified 10% sample of 260 educational scenarios balanced across six risk categories, comparing six general defenses against education-specific variants, in which "taxonomy-augmented classi- fiers achieve the largest ASR reductions". SG+T showed the most balanced performance; GOS+T excelled on privacy, misinformation, and academic misconduct.

"Among them, taxonomy-augmented classi- fiers achieve the largest ASR reductions: SG+T (-30.1 pp), GOS+T (-25.6 pp), and LG3+T (-22.2 pp)."

Discussion¶

Related Claims¶

• Current LLMs are more vulnerable to education-specific risks such as academic misconduct and excessive cognitive load than to conventional safety risks in K-12 educational interactions — related
• LLM attack success rates increase consistently from single-turn to static multi-turn and dynamic multi-turn interactions in educational settings — related
• No evaluated LLM tutor is reliably safe: every model exceeds 60% harm rate on at least five risk categories in single-turn and six in multi-turn evaluation — related
• Multi-layer defense significantly reduces bypass relative to regex-only filtering (69.65% to 46.34%), confirmed by exact McNemar test — related
• Head-to-head comparison exposes a security-usability-latency tension: NeMo reaches 0% bypass at 16.22% FPR and ~1.5 s latency while Prompt Guard yields 38.48% bypass at 3.60% FPR — related
• A four-layer multi-layer defense pipeline achieves 46.34% bypass and 0.00% false positive rate on the holdout benchmark — related
• Risk category explains the largest share of variation in educational attack success, far more than LLM usage context or curriculum topic — related
