Employee competency measures what aspect of forensic analysts?

The chosen answer accurately reflects that employee competency encompasses the skill and proficiency of forensic analysts. Competency measures how well an analyst can perform their duties, which includes their ability to apply techniques effectively, analyze evidence accurately, and produce reliable results. This concept is critical in forensic science, where precision and accuracy are paramount in investigations.

While the other options touch on related aspects of an analyst's capabilities, they do not capture the full scope of what competency entails. For instance, knowledge and skill focus primarily on theoretical understanding and practiced abilities, but competency extends beyond them to include how these elements are integrated into actual performance in forensic scenarios. Similarly, the amount of training relates to qualifications rather than competency itself. Lastly, while stating "the competency of an analyst" is somewhat vague, it does not convey the specific skills and proficiency needed to assert effective performance in forensic analysis. Thus, the chosen option comprehensively addresses the definition of employee competency within this context.
