What term is used to describe behavior that is efficient, accurate, and showcases proficiency over time?

Fluency refers to the ability to perform a behavior smoothly and accurately, with a level of efficiency that reflects both speed and precision. It encompasses not just the performance of a behavior but the ability to demonstrate it consistently over time. This makes fluency an important concept in the context of behavioral practices, as it signifies mastery that can be relied upon in various situations.

While competence, expertise, and proficiency are related concepts, they do not fully capture the nuances that fluency provides. Competence indicates basic capability, but does not necessarily imply the efficiency or accuracy of performance. Expertise suggests a higher level of knowledge and skill, often acquired through extensive experience, yet it is not specifically measured in terms of performance speed and accuracy over time. Proficiency implies a degree of skill or competence but still may not emphasize the same blend of speed and accuracy that fluency entails. Thus, fluency is the most appropriate term to describe behavior that is both effective and efficient in terms of demonstration and application.
