ABSTRACT This study focused on trainers’ professional knowledge and skills. Forty-one aspects of trainer knowledge were identified from the empirical research literature and presented in an online questionnaire to 200 trainers, 253 trainees and 93 human resource development practitioners. The respondents rated the importance of each knowledge aspect for the professional activities of a trainer on a six-point Likert scale. The results indicate that subject-matter knowledge and communication techniques are considered vital for trainers, along with content-specific instructional knowledge such as specific training methods. Additionally, trainers are expected to provide clarity and structure, build relationships with trainees and create a constructive learning environment. Implications for future research and training practice are discussed.

从培训师，受训者和人力资源开发从业者的角度讲培训师的知识和技能

摘要本研究侧重于培训师的专业知识和技能。从经验研究文献中确定了培训员知识的41个方面，并以在线问卷的形式向200名培训员，253名受训者和93名人力资源开发从业人员进行了介绍。受访者用六点李克特量表对每个知识方面对培训师的专业活动的重要性进行了评估。结果表明，主题知识和传播技术以及特定于内容的教学知识（例如特定的培训方法）对于培训者至关重要。此外，培训师应提供清晰和结构化的信息，与受训者建立关系并创建一个建设性的学习环境。讨论了对未来研究和培训实践的影响。
