This paper presents a novel approach to develop an automatic scoring system for Situational Judgement Tests (SJTs) using large-scale language models (LLMs). As the importance of measuring personal and professional skills increases, the need for developing an automated system to overcome the limitations of existing human-based scoring methods and conduct SJTs on a large scale is increasing. This study presents a method to extract features related to components from SJT responses using LLMs to solve the validity issue of existing NLP-based systems, and demonstrates its effectiveness using Casper SJT. This study lays the foundation for developing an automatic scoring system for personal and professional skills.
