What does proficiency in a skill imply?

Proficiency in a skill indicates a higher level of skill performance. This means that an individual is not just familiar with the skill or able to perform it at a fundamental level, but instead possesses an advanced capability to execute the skill effectively and efficiently. A proficient individual can typically handle complex situations related to that skill, demonstrate consistency in performance, and make judgments that contribute to achieving desired outcomes in various contexts.

While the concept of proficiency might encompass elements of teaching others or mastering the skill to a complete extent, the key aspect is the ability to perform the skill at a level significantly beyond basic understanding. Proficiency may also imply a solid foundation, but its most notable characteristic is the finesse and adequacy in execution that can greatly enhance the success of tasks or responsibilities related to that skill.
