Training is a vital means to continuously improve service quality. Although much literature has concentrated on the relationship between on-the-job training and job outcomes, these studies are usually static and cross-sectional in research design, which fails to capture the dynamic changes of training outcomes. This study attempted to address this issue by adopting a learning and development perspective. Drawing on psychological capital theory and self-determination theory, we examined how training progress facilitates trainees’ personal growth and psychological development. Specifically, we utilized the latent growth modeling approach to examine hotel employees’ trajectory of change regarding service knowledge, self-efficacy and job satisfaction over the pre-training, mid-training, and post-training stages. By surveying full-time trainees working in three luxury hotels, we found that the mean level of employees’ service knowledge would increase over time, while this improvisation would also result in gradual enhancement of self-efficacy and job satisfaction.

培训是不断提高服务质量的重要手段。虽然很多文献都集中在在职培训与工作成果之间的关系，但这些研究在研究设计上通常是静态的和横断面的，无法捕捉到培训成果的动态变化。本研究试图通过采用学习和发展的视角来解决这个问题。借鉴心理资本理论和自我决定理论，我们研究了培训进度如何促进学员的个人成长和心理发展。具体而言，我们利用潜在增长建模方法来检查酒店员工在培训前、培训中和培训后阶段在服务知识、自我效能和工作满意度方面的变化轨迹。
