Researchers have developed a novel method for estimating the difficulty of multiple-choice questions without needing prior response data. This approach fine-tunes transformer models directly on the item wording, bypassing traditional feature engineering. The study introduces component-wise encoding and multi-task learning extensions to improve accuracy, particularly at smaller training set sizes, with the multi-task variant showing consistent gains across all metrics.
