What type of competency is defined as developed aptitudes or abilities to effectively use one’s knowledge?

The correct answer is skills. Skills are defined as developed aptitudes or abilities that enable an individual to apply their knowledge effectively in practical situations. This encompasses both technical and interpersonal skills, which are essential for executing tasks and navigating workplace dynamics.

In the context of human resources and professional development, skills are built through education, training, and practical experience, and they are crucial for performance in any job role. An understanding of one’s skills helps organizations assess employee capabilities and align them with job requirements.

Achievements refer to successes or accomplishments, which do not specifically relate to the abilities or aptitudes needed to apply knowledge. Credentials encompass certifications or qualifications that validate a person's knowledge but do not inherently imply the ability to use that knowledge effectively. Education is the broader process of acquiring knowledge and information, but it does not necessarily equate to the practical application of that knowledge, which is where skills come into play. Therefore, skills represent the best answer as they highlight the developed abilities that facilitate effective knowledge usage.
