Evaluating the training effectiveness is a critical process. However, it is very important for the improvement process of a training. Training effectiveness can be measured based on the trainee's learning performance throughout the training. High learning performance is an important factor that encourages the transfer of training. A study was conducted to evaluate the learning performance of military officers who attended the G2 and G3 Staff and Tactics Courses at the Officers' College, Port Dickson. This study aims to examine the influence of individual factors such as extraversion and agreeableness personality factors and learning motivation on trainees' learning performance. The data was analysed using SEM-AMOS (Structural-Equation Modeling-Analysis of Moment Structures). The findings of the study found that the three individual factors have a significant influence on learning performance. This shows that individual factors also affect the training effectiveness. Therefore, the responsible parties need to take individual factors into account when planning and designing a training.
