The integration of Large Language Models (LLMs) in K--12 education offers both transformative opportunities and emerging risks. This study explores how students may Trojanize prompts to elicit unsafe or unintended outputs from LLMs, bypassing established content moderation systems with safety guardrils. Through a systematic experiment involving simulated K--12 queries and multi-turn dialogues, we expose key vulnerabilities in GPT-3.5 and GPT-4. This paper presents our experimental design, detailed findings, and a prototype tool, TrojanPromptGuard (TPG), to automatically detect and mitigate Trojanized educational prompts. These insights aim to inform both AI safety researchers and educational technologists on the safe deployment of LLMs for educators.
Study at a glance
  • Question: How can schools prevent students from tricking educational AI tools into producing unsafe or unintended outputs?
  • Setting and data: Simulated K–12 queries and multi-turn dialogues with GPT-3.5 and GPT-4.
  • Method: Systematic experiment testing AI models and development of a prototype detection tool (TrojanPromptGuard).
Why it matters

Integrating Large Language Models in K-12 education brings emerging risks. Students may Trojanize prompts to bypass established content moderation systems and safety guardrails, eliciting unsafe or unintended outputs.

Key findings
  • In simulated K-12 queries and multi-turn dialogues, GPT-3.5 and GPT-4 revealed key vulnerabilities to manipulated prompt chains.
  • Students may elicit unsafe or unintended outputs by using chained prompts that bypass established AI content moderation systems.
  • A prototype tool can automatically detect and mitigate manipulated educational prompts that bypass safety guardrails.
