Competency is important for professionals’ effective performance and career development. However, little is known about the necessary competencies and proficiency in these for Thai safety officers. Therefore, this study aimed to identify the necessary competencies for this group and to compare proficiency in each competency between senior and junior safety officers. A descriptive, cross-sectional study was conducted among 73 safety officers using a self-administered questionnaire. Twenty-five competencies were classified as necessary. Mean proficiency scores were higher for senior safety officers than for more junior safety officers for all examined competencies; however, this difference was not statistically significant for ‘first aid’ or for ‘air sampling and analytical methods’. Regulatory compliance was assessed as the most important competency. Gaps between necessity and proficiency were observed in managing safety programs for the junior group. In both groups, proficiency was lowest in the competency of mental health. The results indicate that Thai safety officers’ training needs may be particularly high for regulatory compliance, managing safety programs, and mental health. Lifelong learning is important for enabling occupational safety and health practitioners to fulfill current requirements in Thailand and elsewhere. Multiple training approaches and a specialist qualification program may encourage competency development, especially for junior practitioners.

能力对于专业人员的有效绩效和职业发展至关重要。但是，对于泰国安全员的必要能力和熟练程度知之甚少。因此，本研究旨在确定该组的必要能力，并比较高级和初级安全官之间每种能力的熟练程度。使用自我管理的问卷调查对73名安全人员进行了描述性的横断面研究。根据需要对25个能力进行了分类。在所有检查过的能力范围内，高级安全主任的平均熟练度得分高于初级安全主任。但是，对于“急救”或“空气采样和分析方法”，这种差异在统计上并不显着。法规遵从性被认为是最重要的能力。在管理初中组的安全计划中，发现必要性和熟练程度之间存在差距。两组的心理健康能力最低。结果表明，泰国安全官员的培训需求对于合规性，安全计划管理和心理健康特别重要。终身学习对于使职业安全和卫生从业人员能够满足泰国和其他地区的当前要求非常重要。多种培训方法和专家资格计划可能会鼓励能力发展，特别是对于初级从业人员而言。精通心理健康的能力最低。结果表明，泰国安全官员的培训需求对于合规性，安全计划管理和心理健康特别重要。终身学习对于使职业安全和卫生从业人员能够满足泰国和其他地区的当前要求非常重要。多种培训方法和专家资格计划可能会鼓励能力发展，特别是对于初级从业人员而言。精通心理健康的能力最低。结果表明，泰国安全官员的培训需求对于合规，管理安全计划和心理健康可能特别高。终身学习对于使职业安全和卫生从业人员能够满足泰国和其他地区的当前要求非常重要。多种培训方法和专家资格计划可能会鼓励能力发展，特别是对于初级从业人员而言。
