Vulnerability of LLMs in Educational Assessmenthttps://doi.org/10.7910/DVN/OV2WAMMilani, AlfredoHarvard Dataverse2025-09-122025-09-12T10:47:47ZThe dataset contains the output of experiments on a research project on Vulnerability of LLMs in Educational Assessment. The Dataset contains: -the students assignments data in normal form and the injected form -the output produced by the experimented LLMs: ChatGPT, Gemini, DeepSeek, Grok, Perplexity and Copilot for the experiments evaluation the assignments, as a single document and collectively as a group of documents, denominated: -User Legitimate LLMs Prompts -Normal (no injection) providing the reference base evaluation -Prompt Injection Pass, one type of injection experiments, called Fail-To-Top, to move an assignment evailuated FAIL by reference base evaluation to PASS, i.e. above 35% of total points. -Prompt Injection to Top25 , a type of injection experiments to move to top 25% an assignment with lowe reference base evaluation . This latter type of experiment come in 3 versions, Fail-To-Top, Sat-To-Top, Good-To-Top where assignment with reference base evaluation respectively: Fail (below 35%), Satisfactory (greater than 25% and belo 50%) and Good (above 50% and below 75%) are considered for injection. The name of the folders and output results files are accordingly self-explanatory .Computer and Information ScienceSocial SciencesLarge Language ModelsPrompt InjectionEducation SciencesEducation EvaluationTrustworthy AIHuman-in-the-Loop AI"When AI is Fooled: Hidden Risks in LLM-assisted Grading" Authors: Alfredo Milani, Valentina Franzoni, Emanuele Florindi, Assel Omarbekova, Gulmira Bekmanova, Banu Yergesh in Education Sciences, ISSN 2227-7102, issn, 2227-71022025-09-12Milani, Alfredo2025-09-12CC0 1.0
