In this article, the variety of interpretations of the concept of professional competence with reference to vocational teachers is reviewed and discussed. Previous vocational teacher research has been found to focus on which professional competencies vocational teacher possess or should demonstrate, with little focus placed on how competence is defined, leaving a gap related to how the professional competence concept is perceived and constructed. Through a conceptual analysis method (CAM), which follows the data collection process of a systematic literature review, the researcher identifies the concept attributes that are commonly shared as well as neighboring concepts associated with professional competence. Findings indicate that only few studies detail solid concept definitions. Furthermore, there is an agreement amongst the researchers on the main attributes of professional competence, including the situated and developmental character of professional competence as well as its relationship with action. In regard to concept use, there are distinct interrelationships between professional competence, professionalism, performance and qualification. Most definitions regard the individual as the reference point and little to no discussion takes place regarding professional competence at a collective level. Because complex concepts like the one under study can lead to confusion, it is suggested that their use should be accompanied by a discussion of their various meanings.

在本文中，参考职业教师对专业能力概念的各种解释进行了回顾和讨论。以往的职业教师研究被发现侧重于职业教师拥有或应该展示哪些专业能力，很少关注如何定义能力，在如何理解和构建专业能力概念方面留下了空白。通过遵循系统文献综述的数据收集过程的概念分析方法 (CAM)，研究人员确定了共同共享的概念属性以及与专业能力相关的相邻概念。结果表明，只有少数研究详细说明了可靠的概念定义。此外，研究人员就专业能力的主要属性达成了共识，包括专业能力的情境和发展特征以及它与行动的关系。在概念使用方面，专业能力、专业精神、绩效和资格之间存在明显的相互关系。大多数定义都将个人视为参考点，在集体层面上几乎没有讨论过关于专业能力的问题。因为像所研究的那样复杂的概念会导致混淆，所以建议在使用它们的同时讨论它们的各种含义。在概念使用方面，专业能力、专业精神、绩效和资格之间存在明显的相互关系。大多数定义都将个人视为参考点，在集体层面上几乎没有讨论过关于专业能力的问题。因为像所研究的那样复杂的概念会导致混淆，所以建议在使用它们的同时讨论它们的各种含义。在概念使用方面，专业能力、专业精神、绩效和资格之间存在明显的相互关系。大多数定义都将个人视为参考点，在集体层面上几乎没有讨论过关于专业能力的问题。因为像所研究的那样复杂的概念会导致混淆，所以建议在使用它们的同时讨论它们的各种含义。
