Automatic Prompt Engineering for Generative AI–Based Essay Scoring

Yue Huang


Abstract
This study evaluated automatic prompt engineering (APE) using one assignment in the PERSUADE 2.0 dataset. The APE approach achieved higher QWK (.812) than the research-informed, zero-shot baseline prompting approach (.646). Descriptive comparisons examined gender and English language learner subgroups. Findings support the benefits of APE for automated essay scoring (AES).
