This work-in-progress study compares the accuracy of machine learning and large language models to predict student responses to field-test items on a social-emotional learning assessment. We evaluate how well each method replicates actual responses and examine the item parameters generated by synthetic data to those derived from actual student data.

This study explores the use of large language models to simulate human responses to Likert-scale items. A DeBERTa-base model fine-tuned with item text and examinee ability emulates a graded response model (GRM). High alignment with GRM probabilities and reasonable threshold recovery support LLMs as scalable tools for early-stage item evaluation.
